It is a mineral formed by volcanic eruptions.
Fu Shi and Fr. Trichosanthis Gua Lou both cool the Lungs and transform Phlegm-Heat, treating Phlegm that stifles the chest and is hard to expectorate. Fu Shi, cold and salty, chiefly dissolves old Phlegm accumulations and nodules and treats Bloody Lin. Gua Lou, sweet and cold, moistens and descends rebellious Qi to relieve discomfort in the chest and leads Phlegm-Heat downward.
Fu Shi and Concha Meretricis/Cyclinae Ge Qiao are both salty and cold; they clear the Lungs, transform viscous Phlegm and soften hardness. Each is used for cough with Phlegm that is hard to expectorate because of Phlegm-Heat, for scrofula and for urinary difficulty. Ge Qiao, being heavy, descends Qi and works to reduce abdominal masses and eliminate Blood Stagnation. Fu Shi, being light, tends to rise into the Lung channel and Upper Jiao.
Fu Shi and Flos Inulae Xuan Fu Hua are both salty and can therefore soften hardened Phlegm; they are commonly combined for clumped, viscous sputum that is hard to expectorate. Xuan Fu Hua, warm, bitter and acrid, leads Qi downward to treat cough, wheezing and nausea. Fu Shi, being cold, is better for hot, viscous Phlegm or for Lung Heat injuring the collaterals and causing hemoptysis.
Calcined Pumex Duan Fu Shi has a mild astringent action that restrains and inhibits.
