The brief.
Origin
Sun-dried pods of Gleditsia sinensis, sustainably wild-harvested from the mountains of Sichuan and Hubei provinces.
Extraction
Whole dried pods (zào jiá) are simmered in soft water for 4 hours, filtered, and concentrated. Naturally rich in triterpene saponins that produce a mild, silky lather.
Sustainability
Wild-harvested from mountain hedgerows where the tree grows without cultivation input. Our supplier belongs to a Sichuan cooperative that leaves 40% of each stand unharvested to protect regeneration.
How it works.
Gleditsia's triterpene saponins have an amphiphilic structure — one water-loving end, one oil-loving end. They surround sebum and dirt in the same way modern surfactants do, but because they're gentler and biodegradable, they leave the scalp's lipid barrier intact.

The record

Traditional use
Chinese imperial hair-and-body wash; Korean traditional scalp rinse; Japanese tea-ceremony hand cleanser.

People often ask.
Does Gleditsia foam like shampoo?
It produces a mild, silky foam — not the aggressive lather of sulphates. That's the point: less foam means less barrier disruption.
