Ginseng is a highly valued herb in the Far East and has gained popularity in the West during the last decade. There is extensive literature on the beneficial effects of ginseng and its constituents. The major active components of ginseng are ginsenosides, a diverse group of steroidal saponins, which demonstrate the ability to target a myriad of tissues, producing an array of pharmacological responses. However, many mechanisms of ginsenoside activity still remain unknown. Since ginsenosides and other constituents of ginseng produce effects that are different from one another, and a single ginsenoside initiates multiple actions in the same tissue, the overall pharmacology of ginseng is complex. The ability of ginsenosides to independently target multireceptor systems at the plasma membrane, as well as to activate intracellular steroid receptors, may explain some pharmacological effects.
Ginseng has a history of herbal use going back over 5,000 years. It is one of the most highly regarded of herbal medicines in the Orient, where it has gained an almost magical reputation for being able to promote health, general body vigour and also to prolong life.
The root is adaptogen, alterative, carminative, demulcent, emetic, expectorant, stimulant and tonic. It both stimulates and relaxes the nervous system, encourages the secretion of hormones, improves stamina, lowers blood sugar and cholesterol levels and increases resistance to disease. It is used internally in the treatment of debility associated with old age or illness, lack of appetite, insomnia, stress, shock and chronic illness. The roots are harvested in the autumn, preferably from plants 6 - 7 years old, and can be used fresh or dried.
A dose of 10ug/ml of ginseng saponins has been shown to be significantly radio-protective when it is administered prior to gamma-irradiation.
The leaf is emetic and expectorant.
Known Hazards: Ginseng is not normally prescribed for pregnant women, or for patients under the age of 40, or those with depression, acute anxiety or acute inflammatory disease. It is normally only taken for a period of 3 weeks. Excess can cause headaches, restlessness, raised blood pressure and other side effects, especially if it is taken with caffeine, alcohol, turnips and spicy foods.
Consuming caffeine with ginseng increases the risk of over-stimulation and gastrointestinal upset. Persons with uncontrolled high blood pressure should not use ginseng. Long-term use of ginseng may cause menstrual abnormalities and breast tenderness in some women. Ginseng is not recommended for pregnant or lactating women.
