Male Infertility

Lipid-soluble antioxidants such as vitamin E have been studied for their effects in male reproductive physiology because the membranes of germ cells and spermatozoa are very sensitive to oxidation (Bhardwaj et al 2000, Bolle et al 2002). According to three of four studies, oral vitamin E supplementation can effectively treat some forms of male infertility (Geva et al 1996, Kessopoulou et al 1995, Rolf et al 1999, Suleiman et al 1996). Doses used varied from 200 mg day to 800 mg day. As with...

Prophylaxis Of Migraine Headache

The first double-blind study investigating feverfew in migraine prophylaxis was published in 1985 and involved 17 patients who had been chewing fresh feverfew leaves on a daily basis (Johnson et al 1985). Therapeutic effect was maintained when capsules containing freeze-dried feverfew powder were continued, whereas those allocated placebo capsules experienced a significant increase in the frequency and severity of headache, nausea, and vomiting during the early months of withdrawal. Since then,...

Migraine

An open-labelled trial investigated the effects of oral CoQ10 supplementation (1 50 mg day) over 3 months in 32 volunteers with a history of episodic migraine with or without aura. CoQ10 significantly reduced both the frequency of attacks and the number of days with migraine after 3 months' treatment (Rozen et al 2002). In 2005, Sandor et al investigated the effects of CoQ10 (300 mg day) taken over 3 months in 42 migraine subjects in a double-blind, randomised, placebo controlled study. 47.6 of...

Herpes Simplex Virus Type

One study using a combination of acyclovir and cloves administered orally found this to be superior to acyclovir alone in the treatment of herpes simplex virus type 1 infection (Kurokawa et al 1995). The combination significantly reduced the development of skin lesion and or prolonged survival times of infected mice and reduced viral loads. Tiger balm is a popular OTC preparation that contains clove oil, menthol, cassia oil, camphor, cajuput oil and sometimes peppermint oil. It is generally...

Inflammatory Diseases

Numerous clinical trials have investigated the effects of fish oil supplementation in several inflammatory and autoimmune diseases, such as rheumatoid arthritis, Crohn's disease, ulcerative colitis, lupus erythematosus and migraine headaches (Belluzzi 2002, Belluzzi et al 1996, Miura et al 1998, Simopoulos 2002). Although not all trials have produced positive results, many of the placebo-controlled trials reveal significant benefit in chronic disease, including decreased disease activity and...

Enhanced Cognitive Function And Alertness

Two recent double-blind studies have confirmed that guarana has significant effects on cognitive function and provide evidence that these effects are not just mediated by the herb's caffeine content (Haskell et al 2005, Kennedy et al 2004). One double-blind, placebo-controlled study assessed the effects of four different doses of guarana (37.5, 75, 1 50 and 300 mg) in 22 subjects (Haskell et al 2005). Cognitive performance and mood were assessed at baseline and again 1, 3 and 6 hours after each...

Hypertension And Cholesterol Lowering

CoQ10 has been studied both as stand-alone and adjunctive treatment in hypertension. According to a review of 8 studies, supplemental CoQ10 results in a mean decrease in systolic blood pressure of 16 mmHg and in diastolic blood pressure of 10 mmHg (Rosenfeldt et al 2003). The effect on blood pressure has been reported within 10 weeks of treatment at doses usually starting at 100 mg daily. One small 10-week open study of 26 subjects with essential hypertension study found that an oral dose of 50...

Reduces Serum Cholesterol Levels

A 2000 meta-analysis of 13 clinical trials concluded that garlic is superior to placebo in reducing total cholesterol levels, exerting a modest effect (Stevinson et al 2001). The mechanism of action involves inhibition of cholesterol synthesis by deactivating HMG-CoA reductase via enhanced phosphorylation, but not changing theamount of the enzyme, according to in vitro research (Liu & Yeh 2002). The compounds containing an allyl-d sulfide or a I lyl-su If hyd ryl group are most likely...

Hypercholesterolaemia And Hypertriglyceridaemia

Niacin has been used for the treatment of hypercholesterolemia and hypertriglyceridaemia since the 1950s. Large doses of niacin reduce total cholesterol, LDL-cholesterol, triglycerides and lipoprotein (a) levels and also markedly raise HDL-cholesterol C levels (lllingworth et al 1994). Considering these factors are also predictive of cardiovascular events, niacin is used to reduce overall risk of cardiovascular disease (Canner et al 1986). According to a recent meta-analysis effects on LDL-...

High Cholesterol

Probiotics modestly reduce cholesterol levels in healthy subjects and may have stronger effects in people with hyperlipidaemia. A meta-analysis of six studies of a probiotic dairy product containing Enterococcus faecium found that the fermented yoghurt product produced a 4 decrease in total cholesterol and a 5 decrease in LDL-cholesterol (Agerholm-Larsen et al 2000). In another study, 32 subjects with serum total cholesterol ranging from 5.7 to 7.25 mg dL were randomly assigned to two...

Answers To Patients Frequently Asked Questions

Astragalus appears to have numerous biological effects, such as digestive and immune system stimulation and heart muscle stimulation. Early research suggests that it may have a role in the treatment of asthma, memory deficits, elevated cholesterol levels and as an adjunct to chemotherapy treatment for cancer. When will it start working This will depend on the indication and dose some studies have shown that effects can begin within 2 weeks. Are there any safety issues Overall the herb appears...

Deficiency Signs And Symptoms

Beta-carotene is considered a conditionally essential nutrient and becomes an essential nutrient when the dietary intake of retinol (vitamin A) is inadequate. Low serum beta-carotene levels have been associated with male gender, younger age, lower non-HDL-cholesterol, greater ethanol consumption and higher BMI (Brady et al 1996), increased lipoprotein density and the presence of inflammation (Kritchevsky 1999), high C-reactive protein (Erlinger et al 2001), high blood glucose (Abahusain et al...

Cardiovascular Protection

There are a number of ways in which beta-carotene may act to protect against cardiovascular disease. Free radical scavenging may prevent cellular transformations leading to atherosclerosis and protection of LDL oxidation may further act to protect against atheroma formation (Halliwell 1993). Other mechanisms proposed for the possible favourable effect of antioxidants include an increase of HDL cholesterol and the preservation of endothelial functions (Tavani & La Vecchia 1999). Patients with...

Cardiovascular Disease

Epidemiological studies support the idea that a diet rich in high carotenoid containing foods is associated with a reduced risk of heart disease (Kritchevsky 1999). A review of observational and intervention studies on beta-carotene and the risk of coronary heart disease found that seven cohort studies (Gaziano et al 1995b, Gey et al 1993, Knekt etal 1994, Manson etal 1991, Morris et al 1994, Rimm et al 1993, Street et al 1994) reported relative risks between 0.27 and 0.78 for high serum...

Lipidlowering Activity

Although the mechanism of action is yet to be fully explained, studies show that chromium supplementation may decrease triglyceride levels, total and LDL-cholesterol and modestly increase HDL-cholesterol (Bahijri 2000, Lee & Reasner 1994, Press et al 1990, Preuss etal 2000). ANTIDEPRESSANT NEUROTRANSMITTER EFFECTS Depression is often associated with insulin resistance, owing to Cortisol overproduction (McCarty 1994). The reputed antidepressant effects of chromium may be explained by...

Prevention Of Morbidity And Mortality Of Cardiovascular Disease

For over 25 years, fish and fish oils have been linked to cardiovascular health. This association was first recognised when significantly lower death rates from acute myocardial infarction (Ml) were found among Greenland's Inuit population, despite only moderate differences between the Inuits' blood cholesterol levels and those of other populations (Holub 2002). A high dietary omega-3 fatty acid intake in the form of marine mammals (seal, whale) and various fish were thought responsible for the...

Elevated Triglyceride Levels

DHA and EPA supplementation significantly reduces triglyceride levels and is used as sole therapy in cases of elevation or as adjunctive therapy with cholesterol-lowering medication when indicated. According to Din et al, omega-3 fatty acids reduce triglyceride concentrations in a dose-dependent manner, with intakes of about 4 g day lowering serum triglycerides by 25-30 (Din et al 2004). Overall, it appears that the smallest amount of omega-3 PUFA needed to lower serum triglyceride levels...

Aphrodisiac

The observed pharmacological effects on androgen status provide a theoretical basis for this activity, but little clinical testing has been conducted. Results from a 2002 animal study have produced positive results suggestive of aphrodisiac activity (Gauthaman et al 2002). The study compared the effects of subcutaneous testosterone, an orally administered tribulus extract containing protodioscin (45 dry weight) or placebo over 8 weeks in castrated rodents. Both testosterone and tribulus...

Enhances Dermal Wound Healing

A 2002 study in mice found that topical application of grapeseed PCs considerably accelerate wound contraction and closure and provided additional support during the wound healing process (Khanna et al 2002). Chloasma Chloasma is a condition characterised by hyperpigmentation and is generally considered recalcitrant to treatment. Proathocyanidin-rich GSE successfully reduced hyperpigmentation in women with chloasma after 6 months of oral treatment according to an open study involving 12...

Background And Relevant Pharmacokinetics

Lutein and its isomer zeaxanthin are yellow-coloured, xanthophyll carotenoids that are not converted into vitamin A. The bioavailability of lutein and zeaxanthin from food sources is influenced by the food matrix and the type and extent of food processing, but most notably by the presence of fat in the diet (Castenmiller et al 1999), with dietary fat intake being inversely related to serum levels (Nolan et al 2004). Cooking may increase their bioavailability by disrupting the cellular matrix...

External Treatment Of Minor Inflammatory Conditions And Wounds

Myrrh is incorporated into salves and topical preparations for the treatment of bed sores, minor wounds and haemorrhoids. Although no clinical trials are available, the antimicrobial, anti-inflammatory, astringent and local anaesthetic activities of myrrh provide a theoretical basis for efficacy. HYPERLIPIDAEMIA, HYPERCHOLESTEROLAEMIA, HYPERTRIGLYCERIDAEMIA Szapary et al (2005) conducted a double-blind, placebo-controlled, randomised trial with 103 subjects with LDL-cholesterol levels of...

Pregnancy Use

Insufficient reliable information is available to determine safety. PRACTICE POINTS PATIENT COUNSELLING 100 tea tree oil is a safe and effective alternative to clotrimazole for the treatment of toenail onychomycosis. Extensive in vitro testing has found significant activity against a wide range of bacterial and fungal microorganisms, such as common skin pathogens. 5 tea tree oil gel has been shown to significantly improve acne vulgaris, with effects similar to 5 benzoyl peroxide lotion....

Sex Hormones

Testosterone Whether licorice consumption affects testosterone levels is still unknown, as conflicting results have been obtained from clinical studies. Armanini et al have conducted a series of trials investigating the effects of licorice on testosterone levels in males with mixed results (Armanini et al 1999, 2003a). One study showed that licorice (7 g day equivalent to 0.5 g GA) was able to reversibly reduce testosterone levels within 7 days, by inhibiting 17,20-lyase (involved in the...

Clinical Use

In practice, valerian is rarely used as a stand-alone treatment and is often combined with other sedative or relaxant herbs, such as chamomile, passionflower, skullcap, lemon balm and hops. INSOMNIA Numerous RCTs have investigated the effects of valerian as a treatment for insomnia. Although not all results are positive, results from several well conducted placebo-controlled studies suggest that valerian decreases sleep latency and increases sleep quality in poor sleepers. Preliminary evidence...

Prevention Of Damage From Toxins

Ginseng extract has been shown to be beneficial in the prevention and treatment of testicular damage induced by environmental pollutants. Dioxin is one of the most potent toxic environmental pollutants. Exposure to dioxin either in adulthood or during late fetal and early postnatal development causes a variety of adverse effects on the male reproductive system. The chemical decreases spermatogenesis and the ability to conceive and carry a pregnancy to full term. Pretreatment with 100 or 200 mg...

Longevity

In 2002, Panagiotakos et al found that adherence to a Mediterranean diet and healthy lifestyle (non-smoking, physically active, moderate drinking) is associated with a greater than 50 lower rate of all-cause and cause-specific mortality, such as from coronary heart disease, cardiovascular diseases, and cancer (Knoop et al 2004). The cohort study involved 1507 apparently healthy men and 832 women, aged 70-90 years in 11 European countries and was conducted from 1988 until 2000. A year later,...

Dyspepsia And Related Symptoms

Cinnamon bark oil and crushed cinnamon bark is used in the treatment of dyspeptic conditions, such as mild spastic conditions of the gastrointestinal tract, fullness and flatulence, loss of appetite and diarrhoea. Although controlled studies are unavailable, evidence of antispasmodic and antifoaming activity in animal models and a long tradition of use provide some support for its use in these indications. Cinnamon bark and Chinese cinnamon are approved by the German Commission E for the...

Contraindications And Precautions

Vi) People with fair skin undergoing UV treatment should use high doses of SJW with caution. Suspend use of SJW 2 weeks prior to major surgery. A study conducted in an experimental animal model found no adverse effects on offspring with maternal use however, safe doses in pregnant women have not been determined. In practice, it is not used in pregnancy. St John's appears to be relatively safe in lactation. A study of breast feeding mothers indicated that low levels of hyperforin are excreted...

Cholesterol Reduction

Flavonoids are known to reduce cholesterol. A 30-day study of induced hyperlipidaemia in rats found that baicalein, quercetin, rutin and naringin reduced cholesterol, with baicalein being the most potent. Baicalein was also the most effective flavonoid in reducing triglyceride levels (De Oliveira et al 2002). In another in vivo study, rats were fed a cholesterol-laden diet and half were also given 5. baicalensis radix extract (Regulska-llow et al 2004). The treatment rats displayed a...

Atopic Dermatitis And Eczema

Probiotics have the potential to moderate inflammatory and immune responses and strengthen the intestinal barrier function, three actions that are useful in addressing the underlying pathophysiological processes involved in atopic dermatitis (AD) and eczema (Rosenfeldt et al 2004). The use of probiotic therapy to prevent allergic disease has been demonstrated in studies using L. rhamnosus GG in neonates, whereas studies in infants and children with established AD have found that probiotics...

Reward Deficiency Syndrome

Tyrosine depletion appears to affect reward-based processing (McLean et al 2004) and tests involving reward punishment processing are affected by dopamine depletion (Roiser et al 2005). A lack of D2 receptors and or dopamine depletion states have been implicated in a number of conditions or destructive behaviours thought to be caused by poorly functioning biochemical reward systems. Individuals tend to be at risk of multiple addictive, impulsive and compulsive behavioural problems, such as...

Antiinflammatory

The anti-inflammatory action of GA is largely mediated by Cortisol, an endogenous hormone with anti-inflammatory action (Teelucksingh et al 1990). Several studies have found that GA inhibits the activity of 11 HSD and hepatic delta-4-5-beta-steroid reductase, preventing the conversion of Cortisol to its inactive metabolite, cortisone (Kageyama et al 1997, MacKenzie et al 1990, Soma et al 1994, Whorwood et al 1993). As such, Cortisol activity is prolonged and levels may rise, thereby increasing...

Antihypertensive

In the 1970s Yamagami et al observed a deficiency in CoQ10 in patients with hypertension (1975, 1976) and suggested that correction of the deficiency could result in hypertensive effects. Small studies were initially conducted with hypertensive patients identified as CoQ10 deficient. Since then, significant antihypertensive activity has been observed in several clinical studies (Burke et al 2001, Digiesi et al 1994, Langsjoen et al 1994), however, not all have identified the subjects' baseline...

Interleukin2 Immunotherapy

Clinical trials using l-carnitine (1 g day orally) found that it may be used successfully to prevent cardiac complications during IL-2 immunotherapy in cancer patients with clinically relevant cardiac disorders (Lissoni et al 1993). Thus a beneficial interaction is possible under professional supervision. Research into the use of l-carnitine 4 g day for 7 days showed a reduction in fatigue resulting from treatment with cisplatin (Graziano et al 2002) beneficial interaction is possible under...

Dyspepsia

In a systematic review of herbal medicines for functional dyspepsia, Coon and Ernst (2002) found 17 randomised clinical trials, 9 of which involved peppermint and caraway combination preparations with 60-95 of patients reporting improvements in symptoms. An enteric-coated capsule (Enteroplant) containing 90 mg peppermint oil (WS-1340) and 50 mg caraway oil (WS-1520) has been shown in a double-blind, placebo-controlled multicentre trial with 45 patients to significantly improve symptoms of...

Tinea Pedis

Under double-blind, randomised test conditions 104 subjects with tinea pedis (athlete's foot) used 10 w w tea tree oil cream or 1 tolnaftate or placebo creams as treatment (Tong et al 1992). In this study, significantly more tolnaftate-treated patients (85 ) than tea tree oil (30 ) and placebo-treated (21 ) patients showed conversion to negative culture at the end of therapy. However, tea tree oil cream reduced symptoms as effectively as tolnaftate 1 . A more recent randomised, double-blinded,...

Antidiabetic

Gymnema's antidiabetic activity appears to be due to a combination of mechanisms, including reduction of intestinal absorption of glucose (Shimizu et al 2001), inhibition of active glucose transport in the small intestine (Yoshioka 1986), suppression of glucose-mediated release of gastric inhibitory peptide (Fushiki et al 1992), increased activity of the enzymes responsible for glucose uptake and use (Shanmugasundaram et al 1983), stimulation of insulin secretion (Persaud et al 1999, Sugihara...

Important Cofactor In Many Biochemical Reactions

As a constituent of over 300 metalloenzymes, zinc is involved in myriad chemical reactions that are important for normal body functioning, such as carbohydrate metabolism, protein and DNA synthesis, protein digestion, bone metabolism and endogenous antioxidant systems (Beers et al 1999, Wahlqvist et al 1997, Wardlaw et al 1997). At the cellular level, the function of zinc can be divided into three categories catalytic, structural and regulatory (King 2003). Growth and development Zinc is...

Anticancer

Oral intake of standardised P. ginseng extract demonstrates a dose dependant (1, 3 or 10 mg kg) chemoprotective and antimutagenic effect in animal studies (Panwar et al 2005) and ginsenoside Rg3 has recently been produced as an antiangiogenic anticarcinogenic drug in China (Shibata 2001 ). Chemoprotection Oral administration of red ginseng extracts (1 in diet for 40 weeks) significantly (P < 0.05) suppressed spontaneous liver tumour formation in male mice. Oral white ginseng was also shown to...

Chemoprotective And Adjunct In Cancer Therapy

Rosemary was used topically to treat cancer in ancient Greece and South America. Although controlled trials are yet to be conducted, it has been suggested that rosemary may delay and inhibit tumour formation in women with breast cancer (Abascal & Yarnell 2001) and that it has potential as a preventive agent or as an adjunct in cancer therapy. An in vitro study in human breast cancer cells found that rosemary extract increased the intracellular accumulation of commonly used chemotherapeutic...

Vaginitis And Cervicitis

Clinical data support the use of tea tree oil for vaginitis and cervicitis caused by Trichomonas vaginalis or Candida albicans (WHO 2003). An open study found that intravaginal application of tampons saturated in a diluted emulsified solution successfully healed vaginitis and cervicitis (n 130) caused by T. vaginalis. Vaginal pessaries containing 0.2 g essential oil inserted nightly eradicated symptoms of leucorrhoea and burning in 86 of women with C. a b 'cans vaginitis after 30 days in with...

Viral Myocarditis

Findings from a recent Cochrane systematic review of Chinese herbs used in viral myocarditis provide limited supportive evidence for its use however, further research is required before a definitive conclusion can be made (Liu JP et al 2004). Several in vivo and in vitro studies have found some antagonistic effects on the enterovirus coxsackie B and a reduction in myocardial injury (Lu et al 1999, Peng et al 1995, Rui et al 1993, Yang et al 1990) thought to be due to the astragalosides in the...

Antiretroviral And Antibacterial

Although in vitro and studies in animal models have identified antiretroviral activity for hypericin and pseudohypericin (Meruelo et al 1988), two clinical trials could not confirm these effects, even when larger doses of hypericin were administered (Gulick et al 1999, Jacobson et al 2001). The mechanism involved is not known however, it is suspected to involve direct inactivation of the virus or prevention of virus shedding, budding or assembly at the cell membrane (Meruelo et al 1988). The...

Antiinflammatory And Antithrombotic

Several constituents within olive oil and or leaf have demonstrated anti-inflammatory properties, chiefly oleuropein, hydroxytyrosol, oleic acid, luteolin and apigenin (de la Puerta et al 2000, Makin et al 2003). Oleuropein and hydroxytyrosol are found in both the oil and leaf and inhibit leukotriene B4 generation, which is involved in a wide range of pro-inflammatory pathways (Petroni et al 1997). These polyphenols are able to inhibit platelet aggregation and lipoxygenases and eicosanoid...

Ophthalmic Conditions

Bilberry preparations have been used to improve poor night vision, light adaptation and photophobia, myopia and to prevent or retard diabetic retinopathy, macular degeneration and cataracts. Primarily the collagen-enhancing and antioxidant activities of bilberry provide a theoretical basis for these indications. Visual acuity and light adaptation A systemic review of 12 placebo-controlled trials (5 RCTs and 7 placebo-controlled non-randomised trials) concluded that the 2007 Elsevier Australia...

Bone Marrow Stimulation During Chemotherapy

Haemopoiesis was studied in 88 patients with lung cancer during combination treatment with chemotherapy and a 5. balcalensls extract. Administration of the plant preparation was associated with haemopoiesis stimulation, intensification of bone marrow erythrocytopoiesis and granulocytopoiesis, and increased numbers of circulating precursors of erythroid and granulomonocytic colony-forming units (Goldberg et al 1997). EPILEPSY (IN COMBINATION WITH OTHER HERBS) Saiko-keishi-to, a spray-dried...

Cardiovascular Diseases

In 1972 Folkers and Littaru from Italy documented a deficiency of coenzyme Q10 in human heart disease (Ernster & Dallner 1995). Since those early reports, a steady stream of research articles have been published and clinical experience in its use as an adjunct to conventional treatment in various forms of heart disease has accumulated. Data from laboratory studies have also accumulated and generally provide a supportive basis for its use. A review by Langsjoen and Langsjoen of over 34...

Breast Cancer

There is suggestive evidence of a preventive role for iodine in breast cancer. As far back as 1896 research has suggested a link between iodine deficiency, thyroid disease and breast cancer (Smyth 2003). More recently, epidemiological data have demonstrated a correlation between increased incidence of breast cancer and a range of thyroid conditions, most notably hypothyroidism (Smyth 2003). In addition, the observed low rates of breast cancer in Japan are speculated to be partly due to a high...

Anxiolytic And Sedative

Over the years, a number of studies involving rodents have suggested specific anxiolytic or sedative effects (Kennedy et al 2002, Soulimani et al 1991). More recently, a double-blind placebo-controlled study has confirmed anxiolytic activity is clinically significant for lemon balm essential oil (Ballard et al 2002). In 2005 a double-blind, placebo-controlled, randomised, crossover trial of a whole extract of lemon balm (300 and 600 mg) in 18 healthy adults found a significant reduction in 2007...

Statin Drug

The mechanism of action of the statin group of drugs is inhibition of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA)-reductase, an enzyme involved in the biosynthesis of cholesterol from acetyl-CoA. Inhibition of this enzyme also adversely effects the intrinsic biosynthesis of CoQ10, as demonstrated in laboratory animals and humans and reduces plasma and myocardial levels of CoQ10 (Bargossi et al 1994b, Folkers et al 1990, Rosenfeldt et al 2005). Studies have indicated that reductions of 20-30...

Antispasmodic

Peppermint oil, ethanol extracts and flavonoids isolated from the leaf have all been shown to have antispasmodic (spasmolytic) effects in vitro (ESCOP 1997) with the effect mediated via smooth muscle calcium channels (Hills & Aaronson 1991). In healthy volunteers, intragastric administration of a dose equivalent to 180 mg peppermint oil reduced intraoesophageal pressure within 1-7 minutes of infusion (Kingham 1995), while in nine human studies involving 269 subjects peppermint oil produced...

Osteoporosis Prevention

The clinical data suggest that approximately 80 mg day isoflavones are needed to derive skeletal benefits, whereas limited epidemiologic data among Asian populations generally suggests that lower amounts are efficacious (Messina et al 2004). The relationship between usual soy food consumption and fracture incidence was studied in 24,403 postmenopausal women aged 40-70 years who had no history of fracture or cancer in the Shanghai Women's Health Study. During a mean follow-up of 4.5 years a...

Toxic Liver Damage

Mushroom poisoning (Amanita phalloides) One of the best documented uses of milk thistle is in the treatment of poisoning by the mushroom Amanita phalloides (death cap). Nausea, vomiting, abdominal cramps and severe diarrhoea usually occur 8-12 hours after ingestion with extensive hepatic necrosis occurring 1-2 days later. A mortality rate of 20-30 has been observed but can be as high as 50 in children under 10 years of age (Floersheim et al 1982). Several clinical studies have shown silybin...

Rheuma Toid Arthritis

Evening primrose oil supplementation leads to an elevation of DGLA, which is a competitive inhibitor of pro-inflammatory PGs and leukotrienes, and therefore results in a reduced inflammatory response (Belch & Hill 2000). As such, EPO supplements have been investigated in the management of RA, with both negative and positive results (Belch et al 1988, Brzeski et al 1991, Hansen et al 1983, Jantti et al 1989, Veale et al 1994, Zurier et al 1996). In one study, 16 patients with RA were given...

Dermatological Uses

Vitamin C is used as an oral supplement or topical application in a number of dermatological conditions. Wound healing Vitamin C is important for effective wound healing, as deficiency contributes to fragile granulation tissue and therefore impairs the wound-healing process (Russell 2001). In vitro studies with skin graft samples have demonstrated that vitamin C extends cellular viability, promotes formation of epidermal barrier and promotes engraftment (Boyce et a I 2002). In this way, vitamin...

Atherosclerosis

Oxidative modification of LDL in the vascular wall seems to be a key factor in atherosclerosis development and thus lipid-soluble antioxidants that can protect LDLs may have a role in atherosclerosis prevention (Cherubim et al 2005) however, the relationship between lutein and zeaxanthin status and atherosclerosis is unclear. Plasma levels of lutein, beta-cryptoxanthin and zeaxanthin were correlated to carotid intima-media thickness in a 3-year case-controlled study of 231 subjects (Iribarren...

Diffuse Oesophageal Spasm

Diffuse oesophageal spasm (DES) is a relatively rare motor disorder. Associated manometric abnormalities may include hypertensive and repetitive contractions. The lower oesophageal sphincter (LES) may also be hypertensive. Although LES relaxation with deglutition is generally normal, disturbances in LES function are often seen. These abnormalities are, however, not required for the diagnosis (Massey 2001). In a study of eight DES patients with chest pain or dysphagia, peppermint oil had no...

Hyperhomocysteinaemia

Together with vitamins B12 and B6, folic acid has been shown to reduce high plasma levels of homocysteine. Of the three, folate appears to have the strongest activity (Voutilainen et al 2001). Although elevated homocysteine has been implicated as a risk factor in cardiovascular disease (including atherosclerosis and coronary artery disease), cerebrovascular disease, peripheral vascular disease and venous thromboembolism (Clarke et al 1991, den Heijer 1996, Malinow et al 1989, Selhub 1995),...

Main Actions

ADAPTOGENIC (MODULATES STRESS RESPONSE) Siberian ginseng appears to alter the levels of different neurotransmitters and hormones involved in the stress response, chiefly at the HPA axis. It degrades the enzyme (catechol-O-methyl transferase), and increases levels of noradrenaline and serotonin in the brain and adrenaline in the adrenal glands, according to animal studies (Abramova et al 1972). Eleutherosides have also been reported to bind to Ginseng_Siberian 577 receptor sites for progestin,...

Anxiolytic

Wogonin, baicalein, scutellarein and baicalin (in reducing order of potency), which all contain a certain flavonoid phenylbenzopyrone nucleus, have been shown in vitro to bind with the benzodiazepine site of the GABA-A receptor (Hui et al 2000). Oral administration of wogonin (7.5-30 mg kg) has been shown to interact with GABA-A receptors and produce an anxiolytic response that was similar to diazepam in the elevated plus-maze. Unlike benzodiazepines, wogonin was able to reduce anxiety without...

Enhance Wound Healing

Pantothenic acid has been both used as an oral supplement and applied topically in a cream base to enhance wound healing and it has been shown to accelerate closure of wounds and increase strength of scar tissue in experimental animals (Plesofsky 2002, Vaxman et al 1990). Although these results are encouraging, there has been little investigation in humans. One double-blind study testing the effects of vitamin C (1000 mg) and pantothenic acid (200 mg) supplements over a 21 -day period showed no...

Clinical

Although Aloe vera products are used for many indications, the chief use is treating skin conditions. SKIN CONDITIONS Aloe is used in the treatment of wounds, burns, radiation burns, ulcers, frostbite, psoriasis and genital herpes. The healing properties may be attributed to antimicrobial, immune-stimulating, anti-inflammatory and antithromboxane activities. Allantoin has also been shown to stimulate epithelialisation, and acemannan has been shown to stimulate macrophage production of IL-1 and...

Warts

Oral zinc sulfate (10 mg kg) supplements administered in three divided doses per day (up to 600 mg day) for 2 months completely cleared recalcitrant viral warts in 87 of patients, according to a single-blind, placebo-controlled trial of 80 volunteers with at least 1 5 viral warts that were resistant to other treatments (Al Gurairi et al 2002). Warts were completed cleared in 61 of patients after 1 month of treatment, whereas none of the patients receiving placebo reported a successful response...

Enhanced Cognitive Function

The results of a double-blind, placebo-controlled study suggests that both milk and dark chocolate, but not white chocolate, improve cognitive function. A second double-blind study suggests that this improvement is due to the methylxanthin content of chocolate, with 11.6 g of cocoa powder producing identical improvements in cognitive function and the mood construct 'energetic arousal' as a mixture of caffeine (19 mg) and theobromine (250 mg) (Smit et al 2004). Consumption of a 65 g chocolate...

Chemical Components

Cocoa is among the most concentrated sources of the flavanols, catechin and epicatechin, with four times the catechin content of tea (Arts et al 1999). Chocolate also contains additional flavonoids not found in tea, with high concentrations of oligomeric procyanidins (Lazarus et al 1999). Post-harvesting and processing pro 2007 Elsevier Australia cedures can have a striking influence on the flavanol content of chocolate and cocoa (Hollenberg et al 2004). Dark chocolate has the highest total...

Hyperlipidaemia

The ability of chitosan to form complexes with various fats, including cholesterol, provides a theoretical basis for its use in hyperlipidaemia. Dietary chitosan has been tested and found to be effective in reducing serum cholesterol levels and atherosclerosis in normal and diabetic mice, and therefore has been investigated in the treatment of hypercholesterolemia in humans (Muzzarelli 1999). A 2002 review states that in humans, dietary chitosan reduces serum total cholesterol levels by...

Chemoprotective

In the 1970s quercetin was considered to be carcinogenic after demonstrating mutagenicity in the Ames test however subsequent long-term studies have refuted this and demonstrated an anticarcinogenic effect in laboratory animals (Erlund 2004). In vitro and preliminary animal and human data indicate that quercetin inhibits tumour growth and induces apoptosis. The anticarcinogenic effects may be due to its antioxidant properties, protection against DNA damage, inhibition of angiogenesis, effects...

Analgesic And Local Anaesthetic

Both the aqueous and lipid-soluble extracts of kava exhibit antinociceptive properties in experimental animal models Jamieson amp Duffield 1990 . The effect is not mediated by an opiate pathway, as naloxone does not reduce the effects when administered in doses that reverse the effects of morphine. More recently, in vitro research has identified several compounds found in kava that have the ability to inhibit COX-1 and to a lesser extent COX-2 enzyme activities Wu et al 2002 . The local...
