Hyperplasia of the breast treated with TCM pumice stone

What is a pumice stone(Fu Hai Shi)?
Pumice rock refers to the hardened foam of lava, which forms during volcanic eruption. It mainly consists of cellular volcanic glass, occasionally with a small amount of crystalline minerals. But its chemical constituents are similar to rhyolite, mainly including SiO2, Al2O3, K2O, and so on.

When it comes to Traditional Chinese medicine (TCM), Fu Hai Shi has a broader meaning, including pumice (Fu Shi) and the dried skeleton of Costazia aculeata Canu et Bassler or Costazia costazii Audouin (Shi Hu), which mainly refers to the skeleton of Porites nigrescens and sometimes a few species of Acropora.

Pumice stones are in the shape of irregular lumps, and slightly oblateness or oblong. They are not of uniform size and with a slightly flat base. They are off-white or pale yellow and with many small pores. They are hard and brittle, easily broken, and with rough cross section. They are so lightweight that they can float in the water. They have a slightly fishy odor and slightly salty flavor. Medicinally the preferred one should be intact, lightweight, off-white, and with globular branches.
