Ci Shi (Magnetite) — Mineral Herb for TCM Decoction & Herbal Formulas

Ci Shi (Magnetite, 磁石) is a mineral-based herb used in Traditional Chinese Medicine (TCM) as a heavy, settling substance traditionally classified among the mineral medicinals. Known in classical texts as Cí Shí (磁石), it has been prized for centuries as a spirit-anchoring and yang-subduing mineral, traditionally used to calm restlessness, quiet the mind, and settle upward-flaring Liver yang. Its nature is salty and cold, making it a heavy, descending herb that works gently yet profoundly within the body's deeper energetic layers.

Quality & Sensory

Each batch is carefully selected and processed to preserve its characteristic dark, iron-grey appearance and dense, weighty texture. The mineral pieces are firm and solid with a faint metallic-mineral aroma. When decocted, Ci Shi releases a subtle mineral taste that blends quietly into the broader flavor of a formula, contributing body and depth rather than a strong flavor of its own.

Traditional Uses

In classical TCM practice, Ci Shi is decocted into formulas alongside herbs such as dragon bone, oyster shell, and rehmannia to anchor the spirit and settle yang. It appears in traditional preparations for calming the mind and supporting restful sleep, and is often included in longer decoctions where its heavy, descending nature balances lighter, upward-moving herbs. In folk herbal practice, it is simmered slowly in water as part of a broader formula rather than used alone.
