A study on the conception vessel / 全日本鍼灸学会雑誌

ABSTRACT

This paper examined the origins of the conception vessel (also known as the Ren meridian) based on references to the conception vessel in the Inner Canon of the Yellow Emperor (Huangdi Neijing, the seminal medical text of ancient China). It takes into consideration new findings related to medical principles, Chinese philology and graphology, and history. We reached the following opinions. It is clear from references in texts such as Lingshu Wuyin Wuwei's mention of underdeveloped innate reproductive functions in men, and the Bone Cavity thesis of the Suwen that states "diseases of the conception vessel appear inside the male as the "seven stomach aches"and in females as mucous discharges from the female genitals and lumps within the bowels", that the conception vessel has existed in both males and females since its discovery. The conception vessel runs along the body's midline, where the following are also locatedthe vestige of the umbilical cord connected to the fetus, the opening of the vagina and urethral opening (from which menstrual blood and semen are discharged, respectively), and the uterus which holds the fetus. Given that these are all located along the midline, it is thought that the conception vessel was formed based on knowledge of the meridian in ancient cosmology. Insight into the origin of the conception vessel can be provided by elucidating the mechanisms of how the human body gives birth to new life by placing focus on both male vitality and female menstruation while avoiding differences in genital structure. These are interpreted using the same criteria as kidney qi, heavenly dew, conception vessel, and the vital channel, suggesting that both share the same roots and are based in the bladder on the body's midline.
