Phyllanthus, Black Fungus and Burdock Root Soup (You Gan Zi Mu Er Niu Bang Tang)

Why people make this soup

Phyllanthus berry — known as oil kan zi in Cantonese, Indian gooseberry or amla in English — has an intriguing property that sets it apart from most vitamin C-rich foods: its ascorbic acid remains stable even after high heat and prolonged cooking, unlike the vitamin C in most fruits and vegetables. This means that even after a long simmer, you still get real antioxidant activity from this fruit. In traditional Cantonese food therapy, phyllanthus is associated with aiding digestion, managing blood sugar, and restraining the effects of diabetes — and is a common sight in flower stalls and herbal medicine stores across southern China. This soup combines it with burdock root (traditionally used for its association with blood glucose and cholesterol management), black fungus (long valued for cardiovascular support), water chestnut (cooling and moistening), and dried figs (gentle and sweet). The result is a soup suitable for middle-aged and older adults as a regular health-maintenance dish.

Method

1. Gently crack each phyllanthus berry with the flat of a knife — this helps release flavor and active compounds into the soup.
2. Soak the dried black fungus until fully soft; drain and rinse. Slice into strips if desired.
3. Scrub the burdock root under running water (do not peel — the skin contains beneficial compounds); cut into sections.
4. Peel the carrot and water chestnuts.
5. Place all ingredients in a pot and add 2.4 L of cold water.
6. Bring to a boil, then reduce heat and simmer for 2 hours until the liquid reduces to approximately 1.2 L.
7. Drink the soup and eat the ingredients to taste. No need to add salt — the natural sweetness of the figs and water chestnut balances the sour phyllanthus.

Nourilo’s Tips

This soup is naturally cooling and refreshing — ideal for summer, or for those who tend toward heat. If someone in the family has a cold constitution (always cold, prefers warm food), add 3 ginger slices and 2 pieces of dried tangerine peel to balance the soup’s nature. As an even simpler daily practice, dried phyllanthus (you gan zi gan) and guava leaf (fan shi liu gan) — each 1 tablespoon — can be steeped as a tea and drunk regularly for mild blood sugar support. Both can be found in herbal tea shops. Phyllanthus tea is naturally sour; if it is too sharp for sensitive stomachs, add a few leaves of stevia (tian ju ye) or drink after meals.
