Peanuts are recognized as a healthy food worldwide, and are considered one of the "Top Ten Longevity Foods" in China. Traditional Chinese medicine believes that the efficacy of peanuts is to harmonize the spleen and stomach, replenish blood and stop bleeding, and lower blood pressure and fat. The main function of "nourishing blood and stopping bleeding" is due to the red coating on the outer layer of peanuts.

　　According to traditional Chinese medicine theory, "the spleen regulates blood", and people with qi deficiency are prone to bleeding. Peanut red clothing can nourish the spleen and stomach qi, thus achieving the effect of nourishing blood and stopping bleeding. This is called "tonifying qi and stopping bleeding" in traditional Chinese medicine.

　　Western medicine believes that peanut red coating can inhibit the dissolution of fibrin, increase platelet content, improve platelet quality, improve defects in coagulation factors, strengthen the contraction function of capillaries, and promote bone marrow hematopoietic function. So it has a significant effect on various bleeding and diseases such as anemia and aplastic anemia caused by bleeding.
