Used to improve blood circulation, particularly in the brain, helping with cognitive disorders like memory loss, dizziness, and headaches due to reduced blood flow. Also applied in treating peripheral vascular diseases, where poor circulation causes pain, numbness, or coldness in limbs. Its vasodilatory effect increases oxygen and nutrient delivery to tissues. Commonly found in formulations for age-related cognitive decline and recovery after stroke or head injury. May support healing in diabetic microangiopathy by enhancing microcirculation.
