When men reach their prime of life, their kidney qi and celestial energy are strong, and their body's growth and development tends to be stable. The physical characteristics of this period are that the body is complete, the muscles and bones are strong, the energy is strong, the physical strength is strong, and the sexual and reproductive functions are at their peak. However, during this period, men often suffer from stagnation of liver qi due to unsatisfactory marriage, family, career and other factors, or damage to the liver and kidneys due to indulgence in sexual activities. Therefore, liver and kidney diseases are more likely to occur, leading to sexual and reproductive dysfunction and diseases of certain reproductive organs. According to the physical characteristics of this period, in terms of health care, we should not only be optimistic and cheerful, content and happy, but also not overwork and injure the body, indulge in sexual indulgence, and avoid the adverse effects and injuries of various physical and chemical factors. In terms of disease treatment, the main focus is on regulating the liver and kidneys, with appropriate supplementation and diarrhea.
