A very important law was mentioned in Classic of Internal Medicine China’s earliest classic work on medicine, called "female seven and male eight ". The meaning of female seven and male eight is that the life rhy-thm of women is related to seven, and the life rhy-thm of men is related to eight. Women's physiology changes markedly every seven years and men's physiology changes every eight years. Therefore, at these rhy-thm points, both men and women must pay attention to health to cope with changes in the body.

This product was developed for women around 35 years of age. The main function is to help solve the physiological problems of middle-aged women. The intake of selenium can supplement women's YangQi and promote the operation of the digestive system such as the spleen and stomach, thereby solving abdominal fat, facial dark spots, constipation and other digestive problems.
