Astragalus membranaceus a.k.a. Huáng Qí, a.k.a. Milkvetch. When I was training for my first marathon a running mentor suggested that I take this herb. It was recommended to him by a doctor friend, who said that not only would it help boost the immune system which can be depleted during training, but it also could help protect the heart. I did my research and started taking it for several years. During that time I never had a cold and my resting heart rate was that of an endurance athlete. Preliminary studies suggest that it also has benefits for breast cancer, hepatitis, lung cancer, & the common cold.
