Ginseng

Unlike drugs which are designed to act against a specific disease or symptom, ginseng has a wide range of uses. Ginseng appears to function by acting as an adaptogen, a nontoxic substance that increases resistance to stress. Adaptogens have a remarkable ability to normalize conditions in the body, restoring homeostasis, and protecting against stress and fatigue.

Ginseng improves brain function, concentration, memory and learning. In addition, it can reduce or normalize heart beat, blood sugar, and cholesterol, stimulate metabolic functions, and increase endocrine activity. Ginseng can stimulate the circulatory system and digestion, quench free radicals, increase resistance to drugs, alcohol, chemotherapy, and other toxins. It is known to improve athletic performance, shorten recovery time after exercise or stressful situations, benefit insomnia and sleep disturbances, stimulate the immune system, and improve sexual function. It is ginseng's ability to normalize conditions in the body that give it this rather long list of benefits.

The medicinal properties of ginseng appear to be due to a group of chemicals called saponins, also known as glycosides or ginsenosides. These chemicals influence the metabolism of neurotransmitters like serotonin and acetylcholine, which are important for optimum mental functioning. Ginseng seems to reduce the activation of the adrenal cortex, and therefore inhibits the alarm stage of stress. Saponins also increase the activity of the lymphocytes, enhancing immune function. Many of the effects of ginseng are due to its ability to regulate the energy in your body and brain.

Precautions: Individuals with high blood pressure should be cautious about using large quantities of ginseng. In Chinese medicine, there are "types" for whom ginseng is contraindicated. Also, Chinese medicine uses ginseng as a tonic, not necessarily on a daily basis.

Dosage: 500mg to 3000mg per day in divided doses.

Sources: Most health food stores carry several varieties of ginseng. There is tremendous variation in the amount of active ingredients found in different types of ginseng and ginseng products. For sources of ginseng see Appendix A on page 165.
