Food Poisoning

How Chinese medicine differentiates food poisoning, the five patterns you'll actually meet in practice, and the points for each. Acupuncture only — no herbs; hydration is the priority in all patterns.

This page is educational, for practitioners and students — it is not a diagnostic tool and does not replace a proper in-person assessment. Bloody diarrhea, high fever, signs of dehydration, or inability to keep fluids down need urgent medical evaluation — acupuncture is supportive at most, never a substitute for medical care in a severe case.
General Acupuncture Points

Acupuncture points traditionally used for food poisoning — 8 key points, used across the patterns below rather than tied to just one.

The Five Patterns

1. Food Stagnation in the Stomach View full pattern →

Clinical manifestations: Sour, rotten-smelling belching; epigastric fullness and distension worse with pressure; nausea or vomiting of sour, undigested food, relieved after vomiting; foul-smelling flatulence and loose stools with sour odor.
Tongue: Normal body with thick, greasy, curd-like coating, thickest in the centre. Pulse: Slippery and full, most prominent at the right middle position.
Treatment principle: Break down undigested food, harmonize the Stomach, descend rebellious Qi.
Note: no moxa. Direct match with this site's own Retention-of-Food-in-the-Stomach slide — fullness relieved by vomiting, sour regurgitation and foul breath are the same markers named there.

2. Damp-Heat in Stomach and Spleen View full pattern →

Clinical manifestations: Foul-smelling, sticky diarrhea; abdominal pain with heaviness sensation; bitter or sticky mouth taste; heavy limbs and foggy head; low-grade fever persisting despite sweating.
Tongue: Red body, possibly swollen with teeth marks, thick yellow greasy coating especially at centre and root. Pulse: Soggy and rapid, often slippery.
Treatment principle: Clear Heat and drain Dampness from Spleen and Stomach.
Note: no moxa. Matched to this site's Damp-Heat in the Stomach slide, the same one used for Bad Breath and Toothache's oral/digestive Damp-Heat pictures.

3. Cold-Damp Invading the Spleen View full pattern →

Clinical manifestations: Watery diarrhea without strong odor; abdominal cramping feeling better with warmth; heavy sensation in limbs and head; no fever or only mild chills.
Tongue: Pale and swollen with teeth marks, thick white greasy coating, excessively moist. Pulse: Soggy or slippery and slow, soft at right Guan.
Treatment principle: Dispel Cold-Damp, warm Spleen Yang.
Note: moxa applicable on REN-12. Direct match — cold epigastrium improved by heat, no thirst, loose stools and nausea are the same markers named on this site's Cold-Dampness-invading-the-Spleen slide.

4. Toxic-Heat

Clinical manifestations: High fever; bloody diarrhea; severe abdominal pain; restlessness and agitation; intense thirst for cold drinks; dark scanty urine.
Tongue: Red body with prickly raised papillae and dry yellow coating. Pulse: Rapid and forceful, often full or overflowing.
Treatment principle: Drain Fire and resolve toxicity, stop bleeding and cool Blood.
Note: no moxa — a medical-emergency-level presentation, seek urgent care. No standalone Toxic-Heat slide exists on this site, so no pattern link is given here.

5. Phlegm-Dampness in the Middle-Burner

Clinical manifestations: Heavy, sluggish sensation in body and limbs; feeling of oppression and stuffiness in chest and upper abdomen; nausea without violent vomiting; loose, sticky stools; drowsiness and mental fogginess.
Tongue: Pale and swollen with teeth marks, thick white greasy coating appearing wet. Pulse: Slippery and often soft or soggy, especially at right middle.
Treatment principle: Dry Dampness and transform Phlegm in the Middle Burner.
Note: no moxa. No deck on this site has a Middle-Burner-specific Phlegm-Dampness slide, so no pattern link is given here.
