Puerarin

The kudzu (Pueraria lobata) is a fast-growing, woody, somewhat hairy vine, Kudzu is one of the earliest medicinal plants used in traditional Chinese medicine. It has many profound pharmacological actions. Traditional Asian healers have long valued kudzu’s root and flowers for treating colds, flu, high blood pressure, chest pain, allergies, and a host of other ailments. And research indicates that a compound in the root (an isoflavone called puerarin) may also increase blood flow to the heart and brain–which may explain certain traditional uses. Kudzu is available in various forms including capsules, tablets, and sliced or chopped dried root.
