Luffa Chinese Herb

Luffa (Si Gua Luo): A Cooling, Bitter Herb for Clearing Heat, Unblocking Channels, and Supporting Respiratory Health

Introduction

Luffa, known as Si Gua Luo (丝瓜络) in Traditional Chinese Medicine (TCM), is the dried fibrous network of the mature luffa gourd. It is valued for its cooling, bitter nature that helps clear heat, unblock channels, and promote the smooth flow of qi and blood. In traditional use, it is often included in herbal soups and decoctions for respiratory and musculoskeletal support.

What Is Luffa (Si Gua Luo)?

Si Gua Luo is the internal sponge-like fiber left after the luffa fruit fully matures and dries. In TCM, it is associated primarily with the Lung, Stomach, and Liver meridians, where it helps clear heat, resolve phlegm, and open obstructions in the channels. Compared to fresh luffa vegetable, the dried fiber is more medicinal and focused on unblocking and clearing actions.
