3.   Huaishan (Dioscorea root, Chinese mountain yam)

This long, stick-like hairy root is known for its mild but nourishing qualities. It is believed to benefit the liver and kidneys, helping the kidney especially, perform its functions better. In Chinese pharmacology, those with a weak constitution are encouraged to eat more of this during the cusp of the seasons, when weather becomes unpredictable.
