Soups
Kudzu Root, Azuki Bean, Coix Seed and Pork Rib Soup
traditionally used to relieve summer heat symptoms, neck and shoulder tension, and sore throat; supports healthy blood pressure
Why people make this soup
Kudzu root is one of the unsung heroes of Cantonese soup-making. The large, earthy root is widely available at Chinese and Asian grocers throughout summer and autumn, and it is particularly well-regarded when the weather is hot and people are sitting in air-conditioned offices all day — the combination of outdoor heat and indoor cold creates a specific pattern of neck stiffness, back tension, headaches, and a dry, irritated throat. Kudzu is traditionally used to promote gentle perspiration, relieve surface tension, cool thirst, and help the body release pathogenic heat outward.
Beyond its traditional reputation, kudzu contains a compound called puerarin (ge gen su), which researchers have associated with dilating coronary and cerebral arteries, supporting blood pressure, and enhancing blood supply to tissues. It also contains trace selenium, an antioxidant mineral. None of this means kudzu cures heart disease — but it is a genuinely interesting vegetable with a broad nutritional profile, and this soup is a satisfying, naturally sweet family dinner that happens to tick a lot of boxes.
Who it suits / who should be cautious
- Well-suited to: the whole family including children and elderly; those with neck, shoulder, or upper back stiffness; those experiencing a dry throat, oral ulcers, or general heat in summer; those with high blood pressure or circulation concerns (as a complementary dietary choice, not a treatment)
- Cautions: pregnant women should replace the coix seed with lablab beans (bian dou), as coix seed is traditionally considered to mildly stimulate uterine contractions. If joints are hot, red, and swollen with dark urine, add 80 g fresh tu fu ling (Smilax glabra root) to the pot.
Why these ingredients (the food-therapy logic)
- Kudzu root (fen ge / gan ge): Promotes gentle perspiration and releases surface tension; quenches thirst; cools heat; associated with supporting neck and shoulder muscles. Puerarin in kudzu is linked in research to cardiovascular and cerebrovascular support.
- Red azuki beans (chi xiao dou): Drains dampness, reduces swelling, supports urination.
- Raw coix seed (sheng yi mi): Resolves dampness and supports spleen function; used throughout Asia for joint comfort and summer wellness.
- Dried tangerine peel (chen pi): Regulates qi, aids digestion, and prevents the soup from becoming too cooling or cloying.
- Honey dates (mi zao): Natural sweetener; balances the cooling herbs.

Bro Niu’s tips
This soup has a naturally sweet, pleasant flavour and is suitable for the whole family — children can drink it freely. Pregnant women should replace the coix seed with lablab beans. If a family member has swollen, hot, red joints along with dark urine, add a large piece of fresh tu fu ling (smooth greenbrier rhizome, about 80 g) to enhance the anti-inflammatory, dampness-clearing effect. This soup is also beneficial for those with mild water retention, as a complement to medical care for conditions involving fluid accumulation.
