A Detailed Guide to the Benefits, Effects and Culinary Uses of Lysimachia christinae (Jinqiancao)

Jinqiancao is one of the traditional commonly used Chinese herbal medicines. It generally refers to the dried whole plant of Lysimachia christinae, a member of the Primulaceae family, and is named for its round leaves that resemble ancient copper coins. Names vary slightly from place to place; in some regions, the legume Desmodium styracifolium or the lamiaceae plant Glechoma longituba is also called jinqiancao, so when purchasing it is important to check the species source to avoid confusion.

From the perspective of traditional Chinese medicine, jinqiancao is rather cool in nature, sweet with a slightly salty taste, and is often used to drain dampness and relieve jaundice, promote urination and treat strangury, and to remove toxins and reduce swelling. In folk practice it is commonly used to help regulate damp-heat jaundice, difficult urination, and sand or stone strangury; some people with stones also take it as a decoction under a doctor's guidance. In everyday use, jinqiancao also frequently appears in formulas that promote bile flow and urination.

As for consumption, jinqiancao can be eaten in quite a variety of ways. The most common is to take an appropriate amount of the dried product, steep it in boiling water, and sip it slowly as a tea; it can also be boiled in water and the liquid drunk. When making soup, it can be stewed together with lean pork, pork ribs and the like for a light-tasting broth; in addition, some people like to boil it with corn silk, Abrus cantoniensis and other ingredients, each with its own emphasis in flavor and use.

It should be noted that jinqiancao is cold in nature, so people with a weak, cold spleen and stomach who are prone to diarrhea should not drink it in large amounts over the long term. Pregnant women and those with special constitutions should consult a physician before consuming it, and people taking medication should also take care to avoid interactions between the properties of the herbs. As a common herbal medicine, moderation and matching the remedy to the condition are key; if discomfort is obvious, you should still seek medical attention in good time rather than relying solely on tea for regulation.
