[Actions]
Clearing and purging fire.
[Nature and Flavor]
Salty, neutral. It descends fire and dissipates blood stasis.
[Indications]
It treats epistaxis caused by lung blood stasis (scrape Renzhongbai, dry it over a new tile with fire, mix and take to stop bleeding immediately), consumptive fever and thirst, involution of smallpox lesions, and gum rot and mouth ulcers.
[Usage]
Use the urine sediment directly, ground into powder. (The sediment scraped from the urinals of young students in elementary schools or from the chamber pots of old monks in mountains is particularly excellent.)
