Kudzu Root
葛根 · Gé Gēn
Eases stiff necks, headaches, and fever-tinged colds
What it does
Kudzu root eases the stiff neck and shoulders that come with tension headaches, and brings down low-grade fevers from colds and flu. In TCM, it releases the surface and generates fluids for the rigid-neck-with-fever pattern. It also calms hot diarrhea and is classical for diabetes thirst. Three trials cover cardiovascular and metabolic effects.
How to take it
Decoct 9–15g of dried kudzu root in water for 25 minutes. Drink 1 cup, 1–2x daily during acute neck-and-shoulder colds or chronic tension.
Try a Ge Gen Tang formula at the first chill of a stiff-neck cold
Use kudzu starch to thicken sauces, soups, and puddings. Mixes into hot water as a soothing drink.
Whisk a teaspoon of kudzu starch into cool water, then heat to make a soothing porridge

Where it comes from
Kudzu (Pueraria lobata) is the same fast-growing vine that's an invasive species across the southern United States. In TCM, it's been valued for over 2,000 years and appears in two famous formulas: Ge Gen Tang for stiff-neck colds, and Ge Gen Qin Lian Tang for hot diarrhea. The root is rich in isoflavones with documented vasodilatory and anti-inflammatory effects. Three clinical trials track its use for hypertension and metabolic markers.
