Hai Fu Shi (Pumice / Costazia aculeata) — Dried Mineral Herb for TCM Decoction

Hai Fu Shi (海浮石), also known as Floating Stone or Pumice, is a traditional mineral-based herb used in Traditional Chinese Medicine (TCM). Sourced from Fujian and naturally sun-dried, this lightweight, porous mineral has been prized for centuries as a phlegm-transforming, mass-softening, and stone-dissolving herb. Its nature is salty and cold, making it a cooling, dispersing agent traditionally used to clear heat, transform phlegm, and soften hardness.

The pieces are pale grey to off-white with a rough, cellular texture and a faint mineral aroma. When decocted, Hai Fu Shi does not dissolve but releases its essence into the water, contributing a subtle salty-mineral note to the finished brew.

Traditional Uses

In folk herbal practice, Hai Fu Shi is decocted into soups and formulas to clear heat, transform phlegm, and soften hardness. It is traditionally paired with herbs like Zhe Bei Mu, Gua Lou, and Mu Li in respiratory and lymphatic support formulas. As a mineral herb, it is often wrapped in cheesecloth before decocting to prevent fine particles from clouding the brew. In some folk traditions, it is also used externally as a compress for localized swelling.
