Function of Puerariae Extract
Puerariae Extract Puerarin is also known as Pueraria lobata. It is an isoflavone derivative with crown-expanding effect isolated from the Chinese medicine Pueraria lobata. It is found in the roots of Pueraria lobata (Willd) Ohwi and Pueraria thunbergiana Benth. It is a white to yellowish crystalline powder with no potential carcinogenic or mutagenic risk. It is soluble in methanol, slightly soluble in ethanol and slightly soluble in water.

It is clinically used for coronary angina pectoris and hypertension.
Puerariae Extract can increase cerebral blood flow and reduce vascular resistance. Puerariae Extract can also protect against myocardial ischemia caused by posterior pituitary hormone. Puerarin has a neuroprotective effect against cerebral ischemia and increases cerebral blood flow by dilating the intracranial arterial vasculature. Puerarin also has a blood pressure-lowering effect, especially in renal hypertension.
Puerariae Extract Puerarin contains saponins, which are protective against immune damage in liver tissues, and the hepatoprotective activity is enhanced by the hydroxyl group at the C-29 position and the C-5"oxygen-containing group. Puerarin is absorbed through the stomach to protect against liver injury, induce apoptosis of activated hepatic stellate cells, effectively reverse chemically induced liver fibrosis, and protect against carbon tetrachloride-induced acute liver injury, and has multiple physiological activities.
