Trichosanthes is a rare plant from Japan. It is mainly distributed in the mountains on the northernmost side of Hokkaido. Because of its very strong toughness and elasticity, it can withstand the harsh local climate all year round. It is related to the environment and is known as the "King of Plants" by the Japanese. The medical value of Trichosanthes was discovered a long time ago. The earliest book in Japan that records Trichosanthes is the "Odawara Chronicles". It was once mentioned that the monks accompanying the army dedicated the extracted formula of Sanxianxiang grass collected from the people to the Odawara nobles in the Tensho period at that time; the main functions of Sanxianxianxiang include healing wounds and shrinking the elasticity of women's lower body skin. In ancient Japan, It is a must-have item for many harem women in the royal family; at the end of the last century, the International Women's Health Joint Research and Development Society in Tokyo, Japan, officially began to conduct research on this topic. In 2003, the long-term research was finally completed, and Sanxian The main stretch gene "2E factor" inherent in spear grass can already be extracted in batches with a purity of more than 68, which will have a very good effect on the contraction of female genitals. It is nearly 10 times better than the ancient simple boiling extraction method. The medicinal value of Sanxianxiang grass has been completely amplified. The above information is also in my opinion. Japan is a country that pays attention to sex. Things should be good, and their medical care is also good. I hope it will be helpful to you!
