Purple Chinese Yam, Chestnut and Chicken Soup

Why people make this soup

Purple Chinese yam is less common than the standard white variety, but noticeably different in both colour and nutritional profile. The vivid purple flesh comes from anthocyanins (the same family of antioxidant pigments found in blueberries and red cabbage), and the yam contains a compound called diosgenin — a natural plant sterol that researchers have noted may support the body’s own sex-hormone synthesis pathways. In Chinese food therapy, purple yam has long been associated with supporting ovarian function, uterine health, and lactation, as well as benefiting men’s reproductive health. This soup is not a medical fertility treatment, but it is a genuinely nourishing family meal with a solid traditional reputation.
