This is an exceptional formula to bringing oxygen into the body especially for the lungs. When I spoke to Dr. Chi about this he said it is a must for smokers to take daily to avoid lung damage. It also is for any lung problem where there is difficulty getting enough oxygen, shortness of breath, emphysema, and asthma are examples. Studies in China showed this product to greatly increase stamina and helps with all kinds of pain. He also said that in studies that were done, morning erectile function was restored to men. Ingredients: 2 caps Hippophae rhamnoides 500 mg, Rhodiola crenulata 500 mg. 2-3 capsules once a day for smokers, 2 twice a day for any other lung problem.
