From The Horse's Mouth

Concerning Cancer treatment (taken from the main site)

"We must reiterate Bing Han Ginseng is a health food that enhances your health and not a cure for sickness. That's why we must not lead consumers into thinking it's a medicine for treating illness and risk misleading consumers. We encourage consumers to consult their doctors when they are not well and then use our product to enhance their health."
