Jin Bu Huan Root (Rumex japonicus) — Dried Yang Ti Gen / Tu Da Huang Herb, 500g

Jin Bu Huan Root (Rumex japonicus), also known in Traditional Chinese Medicine (TCM) as Yáng Tí Gēn (羊蹄根) and Tǔ Dà Huáng (土大黄), is the dried root of a lesser-known traditional herb prized in folk practice as a cooling, blood-cooling, and dampness-clearing botanical. Its nature is bitter and cold, giving it a distinctly descending, clearing character traditionally associated with the Heart, Liver, and Large Intestine channels. A rare 'cold-back' (冷背) herb seldom stocked by mainstream vendors, it is offered here as whole dried root, with optional grinding service available on request.

Quality & Sensory

Each batch is carefully dried to preserve its deep yellowish-brown to reddish-brown color, firm woody texture, and faint earthy aroma. When decocted, the root yields a bitter, slightly astringent infusion with a deep amber tone, characteristic of its bitter-cold nature. Slices and pieces are firm and dense, releasing their character slowly during long simmering.

Traditional Uses

In folk herbal practice, Jin Bu Huan root is decocted alone or in combination with other cooling herbs for traditional preparations associated with clearing heat and cooling the blood. It has long been used in regional folk formulas, and in some traditions the root is simmered for external washes. Because it is a cold-natured herb, it is traditionally paired with warming or harmonizing ingredients in compound formulas. As a rare cold-back botanical, it is most often found in the hands of experienced herbalists and collectors rather than in everyday kitchen use.
