Water Chestnut Soy Milk
Traditionally associated with clearing stomach heat and reducing digestive accumulation
Why people make this drink
Bad breath is a small problem with an outsized social impact. While poor dental hygiene and cavities can certainly be the culprit, Chinese food therapy traces another common cause to the digestive system: when someone regularly eats rich, spicy, or fried foods, or has a constitution prone to stomach heat, that accumulated heat can rise upward and create an unpleasant mouth odour. This simple morning drink is Bro Niu’s practical answer to that pattern — water chestnuts are cooling, crisp, and traditionally prized for clearing digestive heat and moving accumulated matter through the gut, while fresh soy milk adds gentle nourishment. Together they make a pleasant, easy-to-prepare remedy that is taken daily for one to two weeks.
Who it suits / who should be cautious
- Suits: adults with bad breath attributed to stomach heat, frequent spicy or fried food intake, or a tendency toward constipation; also suitable for children who have mild bad breath after illness
- Not suitable for those with a cold-type digestive constitution (weak spleen, frequent loose stools, or poor appetite) — this formula is cooling. Add 2 slices of fresh ginger to reduce its cooling nature
- Soy milk is naturally cooling; do not over-consume if you have a cold spleen or tend to feel cold easily
Why these ingredients (the food-therapy logic)
- Water chestnuts (ma ti): Fresh, crisp, and cooling; in Chinese food medicine they are associated with clearing heat, promoting body fluid, reducing digestive accumulation, and softening stools — a classic ingredient for oral and digestive wellness
- Soy milk: Nourishing and moistening; contains plant-based proteins and is traditionally considered to support lung and stomach yin; has a naturally cooling quality that complements the water chestnuts in this formula
Ingredients (1–2 servings)
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh water chestnuts | 8 pieces | Peel and slice thinly |
| Unsweetened soy milk | 1 cup (~240 mL) | Homemade or store-bought; no sugar preferred |
| Rock sugar or honey (optional) | To taste |
Method
- Peel the water chestnuts and slice them thinly.
- Pour the soy milk and water chestnuts into a small pot.
- Bring to a gentle simmer over medium-low heat and cook for about 5 minutes.
- Drink the soy milk and eat the water chestnuts together.
Bro Niu’s tips
This remedy works best when taken on an empty stomach first thing in the morning. For optimal results, take it daily for 7–10 consecutive days. Bro Niu recommends making soy milk fresh at home in a soy milk maker if possible — the flavour is fuller and the therapeutic quality better. If using store-bought soy milk, choose an unsweetened variety and add a small amount of rock sugar yourself to control sweetness.
If the bad breath has a deeper digestive cause — such as very frequent loose stools or a tongue coating that is thick and white — this cooling formula may not be the right fit. In that case, Bro Niu suggests looking at soups to strengthen the spleen instead, such as a brew with poria (fu ling), white atractylodes (bai zhu), and flat bean (bian dou) with ginger and red dates.

Q (陆太 / Mrs Lu): My husband has thick tongue coating, several loose stools daily, severe bad breath, and seems to have weak digestion. Can he use this soy milk drink? Bro Niu: Your husband likely has spleen deficiency with dampness — this cooling soy milk formula is not suitable for him. Instead, try cooking a brew with poria (fu ling), white atractylodes (bai zhu), and flat bean skin (bian dou yi) to strengthen the spleen and drain dampness. He can also look for the proprietary wellness drink “Jian Pi Qu Shi Yin” from Yu Ren Sheng brand at pharmacies — one packet daily, two boxes continuously, should help. A “Four Gods Pork Rib Soup” (si shen tang) from my website would also be beneficial.

Q (绮华 / Mrs Qi): My teenage son has bad breath. His Chinese medicine doctor said his spleen and stomach are weak and his stomach fire is insufficient. Can he use this water chestnut soy milk? Bro Niu: If the spleen and stomach are weak with insufficient stomach fire, this cooling formula is not suitable. Instead, try stir-fried flat beans (chao bian dou, 38 g), white atractylodes (bai zhu, 15 g), poria (fu ling, 15 g), and honey dates (mi zao, 3 pieces) simmered with lean pork — this helps strengthen the spleen and reduce bad breath. Even a quick warm broth of coriander, spring onion, fresh ginger, and fish slices can help clear oral odour.

Q (anna): My husband has bad breath and frequent gas. Can this food therapy help him? Bro Niu: Frequent bad breath with gas often points to digestive sluggishness. Try a brew with villous amomum fruit (sha ren, 11 g), prince ginseng (tai zi shen, 11 g), poria (fu ling, 15 g), white atractylodes (bai zhu, 15 g), dried tangerine peel (chen pi, 1 piece), and fresh ginger (3 slices) simmered with lean pork — this should improve both symptoms.
