Chun Gen Pi椿根⽪

Ailanthi Cortex · Tree-of-Heaven Bark · Ailanthus Root Bark

Astringent Herbs 收涩药

Overview

The root or stem bark of the tree of heaven, also dispensed as Chun Pi or Chu Bai Pi: bitter, astringent and cold, it dries damp-heat and binds at the same time, which suits chronic damp-heat vaginal discharge, dysentery and bleeding that keep returning. Dry-frying blunts its coldness and strengthens the binding action; vinegar-preparing steers it toward the Liver for abnormal uterine bleeding and discharge.

Contraindications

Cautions

Bitter, cold and binding: wrong for deficiency-cold diarrhea without damp-heat, and it can hold a pathogen in if given at the acute onset of dysentery. Larger doses may cause nausea, vomiting and abdominal discomfort; keep courses short and supervised. Not for patients with Spleen–Stomach deficiency cold.

Contraindicated in pregnancy: Used with caution in pregnancy — practitioner judgment applies
