A drop of semen and ten drops of blood is an incorrect statement. It is a description in literary language, not a medical concept, and the phrase is not found in either ancient or modern medical books. But many people see this phrase as rigid dogma, thinking that semen is semen and blood is fresh blood, and some even use it to denigrate the absurdity of Chinese medicine, neither of which is a scientific attitude. In the Chinese medical text “Yellow Emperor’s Classic of Internal Medicine” the kidney is the main reservoir of essence, essence is the essence of birth, and the essence of the human body refers to the performance related to human vitality and reproductive capacity. The essence of the latter refers to all the food related to diet, because people need to replenish a lot of energy to live, need a lot of nutritious food, and also has the essence of blood homologation, that is, good nutrition is sufficient qi and blood, poor nutrition is insufficient qi and blood. So a drop of semen ten drops of blood does not have medical value, but in different books inside more requirements for male self-restraint, do not indulge in sex, love the health of the body has a certain educational significance.
