Cancer prevention and therapeutics: Panax ginseng.

Panax ginseng has been used as a medicinal plant in China for thousands of years. Current use in Western countries has been diverse, with focused research on cancer therapeutics. P. ginseng apparently mitigates cancer through anti-inflammatory, antioxidant, and apoptotic mechanisms to influence gene expression. Additional mechanisms of investigation include influence on neurotransmission and immunosurveillance. Low toxicity and positive studies in concomitant use with other chemotherapeutic agents is promising. Although there is no conclusive evidence of P. ginseng curing cancer, research has continually found tumor inhibition, especially in the promotion and progression phases.
