Three-Bean Sweet Soup (San Dou Tang)
traditionally associated with clearing heat, supporting healthy digestion, and strengthening the spleen in children
Why people make this soup
Hand-foot-mouth disease spreads easily among young children, particularly those aged 2–5. Common signs include fever, poor appetite, mouth sores, and a rash on the hands and feet. While prevention is mostly about hygiene — thorough handwashing, avoiding crowded spaces when an outbreak is circulating — supportive food therapy has a role to play in keeping young bodies resilient.
Traditional Chinese medicine classifies hand-foot-mouth disease as a “damp-heat” pattern, which points toward food therapy that clears heat, supports the body’s ability to handle “toxins,” and strengthens the spleen (the digestive system). This simple three-bean sweet soup does exactly that — using everyday beans that most households can keep in the pantry.
Bro Niu also shares a practical tip for children who are already suffering from mouth sores and refusing to eat: blend the cooked soup into a smooth paste, set it with gelatine powder, and serve it cold as a jelly. Cold, smooth, and sweet — most children will accept it even when swallowing is painful.
Who it suits / who should be cautious
- Suitable for healthy children (including as a general preventive during outbreaks) and for children who are already unwell and in early recovery.
- Healthy adults can also drink this soup — it is considered a gentle, clearing, everyday drink.
- If a child is currently running a high fever, Bro Niu advises not giving this soup until the fever has resolved; seek medical care first.
- Children with active phlegm-cough can still drink it — simply reduce the rock sugar.
Why these ingredients (the food-therapy logic)
- Yellow soybeans (huang dou): Associated with strengthening the spleen, nourishing the body, and clearing mild heat.
- Black-eyed peas / eyebrow beans (mei dou): Traditionally used to support digestion and reduce dampness.
- Mung beans (lu dou): One of the most widely used cooling and “detoxifying” ingredients in Chinese food therapy, associated with clearing heat and supporting the skin.
- Dried tangerine peel (chen pi): Warms and moves the digestive system, preventing the cooling beans from sitting heavily in the stomach. Also adds a pleasant fragrance to the soup.
- Rock sugar (bing tang): Gentle sweetener that soothes the throat without being cloying.
Ingredients (2 child-sized bowls)
| Ingredient | Amount | Notes |
|---|---|---|
| Yellow soybeans (huang dou) | 1 liang (~38 g) | Soaked 30 min before cooking |
| Eyebrow beans / black-eyed peas (mei dou) | 1 liang (~38 g) | Soaked 30 min before cooking |
| Mung beans (lu dou) | 1 liang (~38 g) | Rinse well |
| Dried tangerine peel (chen pi) | 1 piece | |
| Rock sugar (bing tang) | A small amount | Adjust to taste |
| Water | 5 bowls |
Method
- Rinse and soak the beans for about 30 minutes.
- Place all three beans, the tangerine peel, and the water in a pot. Bring to a boil, then reduce to a simmer.
- Cook for 1 hour, until the beans are completely soft.
- Add rock sugar and stir until dissolved.
- Serve warm. Children can eat both the soup and the beans.
- For children with active mouth sores who refuse to eat: blend the fully cooked soup into a smooth paste, mix with unflavoured gelatine powder according to the packet instructions, pour into a mould, and refrigerate until set. Serve as a cold, soft jelly — the smooth, cool texture is much easier to eat with a sore mouth.
Bro Niu’s tips
This soup is good for healthy children as everyday support, not only when illness is circulating. The key step for children already affected by mouth sores is the jelly technique: blend everything smooth and chill it. If the adzuki bean texture is too firm even after blending, cook the beans extra long until completely collapsed. The cold jelly method is one of Bro Niu’s most practical suggestions for parents of young children.

Q (Vivi): My 1-year-9-month-old daughter has had a fever for 4–5 days. She has white tongue coating, red, swollen gums, and bad breath. The doctor is concerned it might be hand-foot-mouth disease. What can I make? Bro Niu: Combine reed root (lu gen) 5 qian, raw pearl barley (yi mi) 1 liang, light bamboo leaf (dan zhu ye) 2 qian, and 1 cored pear. Simmer in 5 bowls of water down to 2 bowls and give throughout the day to help clear heat. A fever that does not come down over several days needs a doctor’s attention — please do not rely only on food therapy.
-
Q (Phillis): Can a 2-month-old baby with G6PD (favism) drink this soup as a warming milk tea? Bro Niu: For a 2-month-old, use black beans 1 liang and rush pith grass (deng xin cao) 5 bundles, boiled as a gentle opening tea. G6PD babies can use this safely. Give 1 dose per day for 2 days.
