Chuān Liàn Zǐ (川楝子) — Sichuan Chinaberry Fruit
On this page
1. Overview
Chuān Liàn Zǐ (川楝子) — Melia toosendan fruit — is unusual among Qi-regulating herbs in being cold rather than warm. This makes it the preferred choice when Liver Qi stagnation has begun to generate Heat, producing burning epigastric or hypochondriac pain, irritability and a bitter taste. It is best known as the principal herb of Jin Ling Zi San, paired with Yan Hu Suo as a powerful two-herb analgesic for Liver-Heat pain. It also has historical use as an antiparasitic.
