Yin Jing Shi (Silver Mica / Muscovite) — Mineral Herb for Traditional Decoction & Cooking

Yin Jing Shi (银精石), also written as 银晶石 and historically linked with 金精石, 云母石, and 太阴玄精石, is a mineral-based substance used in Traditional Chinese Medicine (TCM) as a traditional medicinal ingredient. In classical Chinese materia medica, silver mica and related mineral stones have been prized as settling, spirit-calming, and fluid-regulating materials used in decoctions and medicinal cooking. Its nature is traditionally described as sweet, salty, and neutral to slightly cold, making it a gentle mineral herb used within traditional formula contexts.

Quality & Sensory

Each batch is selected for its layered, translucent, silvery-white appearance with a faint pearly sheen typical of mica-family minerals. The texture is smooth and slightly flaky, with a mild, neutral mineral aroma and no harsh odor. When decocted, it releases a subtle mineral character that blends quietly into broths and herbal formulas without dominating the taste.

Traditional Uses

In folk herbal practice, Yin Jing Shi and related mica-family minerals are decocted in traditional formulas, sometimes wrapped in cloth before simmering to keep the mineral pieces contained. They are also used in medicinal cooking, added to long-simmered broths and tonic preparations in classical Chinese wellness traditions. Because these are mineral substances, they are typically used in small, guided amounts within a formula rather than as everyday food ingredients.
