One person should eat 5- 10 grams a day. Usually three to five tablets are enough.

Since ancient times, Chinese medicine has always said that "people can't live without ginger for a hundred days."

Legend has it that White Snake stole Xiancao to save Xu Xian. This fairy grass is ginger bud. Ginger is also called "rejuvenation grass" and ginger soup is also called "rejuvenation soup".
