What it does
Asiatic moonseed cools sore throats, throat infections, and inflammatory joint pain. In TCM, it removes toxic heat from the body's surface and channels. The bitter, cooling root is most often given as part of a multi-herb formula for acute throat conditions. Slightly toxic, so it's used short-term and within standardized doses.
How to take it
Decoct 3–9g of dried moonseed rhizome in water for 25 minutes. Drink 1 cup, 2x daily, short-term. Common in throat-support formulas.

Where it comes from
Asiatic moonseed (Menispermum dauricum) grows wild across northeastern China, Mongolia, Korea, and Russia. The crooked, dark-skinned rhizome is the part used. The Chinese name Běi Dòu Gēn means 'northern bean root,' a folk name reflecting its appearance and habitat. The slug 'chinese-cinquefoil' in some databases is a misidentification: actual cinquefoil is Potentilla, an unrelated plant.
