Ginseng--is there a use in clinical medicine?

Panax ginseng occupies an important place among the tonic remedies of Oriental medicine. Pharmacological investigations show that crude ginsenosides can increase non-specific resistance of an organism to various untoward influences. The effects of purified derived derivatives have only recently become better studied in immunological and cell growth studies in animals and in man. This has now provided some evidence to suggest that ginseng is a drug that contains many derivatives with different pharmacological properties, which could be useful in clinical medicine.
