Millettia Root (Niu Da Li), Fresh Yam and Chestnut Pork Shank Soup

Why people make this soup

Millettia root (niu da li, literally “ox great power”) is a mild, warm root that stands apart from most mountain herbs in that it is not cooling or bitter. Traditional practitioners consider it one of the best non-drastic herbs for strengthening the sinews and tendons, supporting people with aching, stiff, or weak joints from rheumatic conditions, kidney deficiency, or simple overwork. Combined with fresh yam (strengthening to the spleen and kidneys), chestnuts (nourishing to the kidneys and tendons), and pork shank (collagen-rich protein), this soup is a delicious, deeply nourishing bowl for any family member dealing with joint complaints, persistent fatigue, or a weak constitution.
