1. Overview
Chuān Jiāo (川椒) — also known as Hua Jiao (花椒) — is the dried fruit husk of Zanthoxylum bungeanum, the Sichuan pepper. It is one of the most powerfully warming herbs in the Chinese pharmacopoeia, with the characteristic tongue-numbing pungency that is also familiar from Sichuan cuisine. Its medicinal use is to warm the Middle Jiao, disperse deep Cold from the Spleen-Stomach and expel intestinal parasites — particularly roundworm. It is the second ingredient (after Wu Mei) of the classical anti-parasitic Wu Mei Wan.

5. Incompatibilities
Chuān Jiāo (川椒) Sichuan Pepper is not listed in either of the two classical incompatibility texts — Shi Ba Fan (Eighteen Antagonisms) or Shi Jiu Wei (Nineteen Mutual Inhibitions). As with every Chinese herb it should be prescribed only as part of a balanced formula by a registered Chinese herbalist (RCHM), who will check for interactions with any other herbs and prescription medications you are taking.
6. Cautions
Contraindicated in Yin deficiency with Heat, pregnancy and Stomach Fire patterns. Mildly toxic in large doses. Standard clinical doses (3–6 g) are safe. Always consult a qualified Chinese herbalist registered with the RCHM.
Pattern contraindications
Contraindicated in Heat patterns, Yin deficiency with Empty Heat, hypertension with Liver Yang rising and during the acute phase of febrile illness. Pregnancy: most warming interior herbs are contraindicated except under expert prescription for specific cold patterns.
Modern drug interactions
May interact with antihypertensives (variable effect) and cardiac medication. Fu Zi (Aconite, prepared) can interact with cardiac glycosides (digoxin) — only prescribed by practitioners trained in toxic-herb safety.
