Chinese Herbs for Bloating and Gas: Finding the Pattern Behind a Swollen Stomach

Written and reviewed by Dr. Michael Koh, Chinese herbal medicine practitioner at The Oriental Herb, Cliffside Park, NJ

A stomach that looks flat at breakfast and six months pregnant by dinner. Trousers that fit in the morning and cut by evening. Gas, belching, a heavy, full feeling an hour after eating. Bloating is one of the most common complaints in our Cliffside Park store, and one of the most satisfying to treat, because Chinese medicine has very specific tools for it. The key, as always, is matching the herb to the pattern. This post belongs with our main page on Chinese herbs for digestive health.

Three patterns, three very different stomachs

1. Food stagnation

Bloating that follows a large or late meal, with sour belching, a thick tongue coating and relief after a bowel movement. The stomach is simply overloaded. Herbs: Shan Zha (Hawthorn) for fatty and meat-heavy meals, Shen Qu and Mai Ya (barley sprout) for starchy meals, Lai Fu Zi (radish seed) for gas. The classic formula is Bao He Wan.

2. Dampness with a weak Spleen

Bloating most days regardless of what you eat, worse with cold, raw or dairy foods, with loose stools, heavy limbs and fatigue. Digestion is too weak to transform food, so it sits. Herbs: Bai Zhu (Atractylodes), Fu Ling (Poria), Chen Pi (tangerine peel), Sha Ren (cardamom), Yi Yi Ren (Coix). Formulas: Xiang Sha Liu Jun Zi Tang, Shen Ling Bai Zhu San. Read our guide to dampness and Spleen Qi deficiency – this is the pattern most often behind weight gain too.

3. Qi stagnation

Bloating that moves around, comes with stress, is relieved by burping or passing gas, and often sits with sighing, irritability and PMS. Herbs: Chai Hu (Bupleurum), Xiang Fu (Cyperus), Hou Po (Magnolia bark), Zhi Ke (bitter orange), Mu Xiang (Saussurea). Formulas: Xiao Yao San, Chai Hu Shu Gan San. See Xiao Yao San.

A simple daily tea while you decide

Chen Pi (aged tangerine peel) with a few slices of fresh ginger, steeped five minutes and sipped warm after meals, is safe for almost everyone and eases all three patterns a little. It is not a treatment, but it tells you quickly whether warming, moving herbs suit you – if the bloating eases, you are probably in pattern 2 or 3.

What to stop eating – by pattern

Pattern 1: smaller, earlier dinners; no second helpings. Pattern 2: iced drinks, smoothies, salads as a main meal, dairy, sugar. Pattern 3: eating at your desk or while upset; carbonated drinks. Everyone: chew slowly. Twenty chews per mouthful sounds silly and reduces bloating in most people within a week.

When bloating is not just bloating

Persistent bloating with unintentional weight loss, blood in stool, severe pain, vomiting, or – in women – new bloating that does not come and go, needs a doctor. Celiac disease, SIBO and ovarian problems can all present as “just bloating”. We will say so if your picture suggests it.

FAQ

Do probiotics help?

Sometimes, mostly in pattern 2. They do nothing for food stagnation or stress bloating, which need different handling.

How long before Chinese herbs for bloating work?

Food stagnation clears in days. The damp, weak pattern takes four to eight weeks of herbs plus diet change, because the digestion itself has to recover.

Can I buy these in your store without a consultation?

Chen Pi, hawthorn and the gentle teas, yes. The formulas are better matched to you first – a ten-minute conversation saves months of guessing.
