Trace element

There is no known function for germanium in the human body, and it is therefore described by scientists as a 'contaminant' in foods such as garlic, which is rich in germanium.

Because of reports that germanium could stimulate the immune system and may be of benefit for Aids sufferers, germanium was for a short time in the late 1980s available as a dietary supplement in two forms: germanium sesquioxide (also known as organic germanium or Ge-132) and germanium lactate citrate. Germanium dioxide, which is known to be toxic, was not sold as a dietary supplement - at least not by reputable suppliers. Unfortunately a number of individuals in Japan did obtain and consume germanium dioxide preparations, and suffered permanent kidney damage. As a result germanium received a very bad press, and there was widespread withdrawal of all germanium supplements. A search of the scientific literature reveals that some individuals who had taken the supposedly non-toxic forms of germanium also suffered kidney damage. It is still not known whether these forms are indeed non-toxic or whether the products in question were contaminated with germanium dioxide. Experts confirm that it may be virtually impossible to manufacture a completely uncontaminated product.

Ginger

Herb

Ginger is known as a 'hot bitter' herb, which promotes gastric acidity and aids digestion. It is a useful herb for many stomach conditions, and a great deal of research has been conducted into its potential benefits. In one study rheumatoid arithritis sufferers using ginger experienced a reduction in joint pain and an improvement in joint mobility. Ginger has also been used successfully against motion (travel) sickness. In animal studies, ginger has been used to reduce blood sugar in diabetic rats, and to reduce blood cholesterol levels in animals fed a cholesterol-rich diet. In Chinese medicine, ginger is considered to be a warming circulatory stimulant which can also remove catarrh and help bronchitic conditions, as well as help to prevent painful menstrual periods.

Ginkgo biloba

Herb

Ginkgo biloba is one of the most widely researched medicinal herbs and has been found most effective for improving capillary strength and circulation. Its beneficial effects on the blood circulation in the brain makes it potentially very useful in Alzheimer's disease and stroke prevention.

Clinical and laboratory tests have shown Ginkgo biloba extract to have significant benefit in the treatment of Raynaud's disease, asthma, chronic cerebral and circulatory problems, senile dementia, tinnitus, macular degeneration and glaucoma. Ginkgo is also a potent antioxidant. It has a stabilizing effect on cell membranes by preventing lipid peroxidation and modulating calcium influx. In a recent study on Chernobyl salvage workers exposed to radiation, Ginkgo biloba supplements reduced the 'clastogenic factors' (markers of damage to DNA) which had been found in these workers and are commonly present after exposure to radiation.

Ginkgo's effects are due to its high flavonoid content, including quercetin, kaempferol and proanthocyanidins, as well as to its terpenoids such as ginkgolides.

Availability: Ginkgo biloba products are widely available in health food shops.
