Limonite (Yu Liang Shi Alias) Classic Formulas … Natural Herb Library

Primary Actions

Astringes the intestines and stops chronic diarrhea - Yu Liang Shi is used for long-standing slippery leakage, especially chronic diarrhea or dysentery from deficiency rather than acute damp-heat attack.
Astringes to stop bleeding - traditional indications include uterine bleeding, blood in the stool, and other lower-body bleeding patterns where containment has failed.
Stops leucorrhea - it is also applied to chronic vaginal discharge when deficiency and failure to secure the lower burner are central to the pattern.

Chi Shi Zhi Yu Yu Liang Tang - the Shang Han Lun formula using limonite with halloysitum rubrum for unremitting diarrhea after improper treatment.
Yu Liang Shi with Chi Shi Zhi - the classic pairing logic for chronic diarrhea, dysenteric leakage, and intestinal slipping from deficiency.
Yu Liang Shi with other astringent hemostatics - later-style use for persistent uterine bleeding or leucorrhea when simple warming herbs are insufficient.

Traditional sources describe Yu Liang Shi / Yu Yu Liang as sweet, astringent, and neutral, entering the Stomach and Large Intestine to secure intestinal leakage and stop bleeding.
The classic scope is chronic, deficiency-type leakage. It is not a general anti-diarrheal for acute infectious illness or unresolved damp-heat toxin.
