Yu Liang Shi (Limonite) — Dried Mineral Herb for TCM Decoction & Herbal Formulas

Yu Liang Shi (Limonite), also written as Yǔ Liáng Shí (禹粮石) or Yú Liáng Shí (余粮石), is a traditional mineral-based substance used in Traditional Chinese Medicine (TCM) as a stabilizing, astringent, and blood-regulating herb. For centuries, this iron-rich mineral has been prized in classical formulas for its ability to anchor and settle, support the Middle Burner, and harmonize the Spleen and Stomach. Its nature is sweet, astringent, and slightly cold, making it a grounding yet gentle mineral herb in traditional decoction practice.

Traditional Uses

In folk herbal practice, Yu Liang Shi is decocted into soups, tonics, and classical formulas to support digestive balance and stabilize the Middle Burner. It is often paired with herbs like oyster shell, dragon bone, and white peony in traditional preparations. As a mineral herb, it is typically simmered longer than botanical ingredients to fully release its properties into the decoction.
