Overview

Jingjie Lianqiao Decoction, known as Keigai-rengyo-to in Japanese Kampo medicine, is a traditional multi-herb formula composed of 17 botanical ingredients.

The formula contains key herbs such as *Schizonepeta tenuifolia* and *Forsythia suspensa*, which are thought to provide anti-inflammatory, antimicrobial, and immunomodulatory effects.
