Quercetin belongs to a group of plant pigments called flavonoids that are largely responsible for the colors of many fruits, flowers, and vegetables. Flavonoids, such as quercetin, provide many health-promoting benefits. They act as antihistamines (which are useful in reducing allergy symptoms) and help reduce inflammation associated with various forms of arthritis.

Eleuthero is a woodland plant native to southeastern Siberia and the Korean peninsula, and adapted to the damp forests of British Columbia, Washington, Oregon, and northern California. A relative of the more famous red ginseng, eleuthero has been used in Traditional Chinese Medicine since about 190 AD. It became a widely cultivated herb after its use as an adaptogen (an herb that helps the body adapt to stress) was discovered by a Soviet scientist named Brekhman in the 1940Ís. It was dispensed to entire cities in Siberia for 10 weeks in early winter to prevent colds and flu, and used as a treatment for radiation exposure after the Chernobyl accident.

E. senticosus is a new addition to Western natural medicine, but has quickly gained a reputation similar to that of the better known and more expensive Chinese Ginseng. Though the chemical make-up of the two herbs differs, their effects seem to be similar. An extensive list of research on E. senticosus with links to PubMed is available.
The herb is an adaptogen, is anticholesteremic, is mildly anti-inflammatory, is antioxidant, is a nervine and an immune tonic. It is useful when the hypothalamic-pituitary-adrenal axis (HPA) is depleted. Symptoms of this condition include fatigue, stress, neurasthenia and sore muscles associated with the hypofunctioning of the endocrine system, and adrenal exhaustion indicated by a quivering tongue, dark circles under the eyes, and dilating/contracting pupils. Eleuthero may alleviate these symptoms.
