The reason why traditional Chinese medicine is used in navel is mainly because navel is located in the focus of human body, which is a very good way to absorb drugs. Umbilical point, also known as Shenque point, is the intersection of up and down, left and right, yin and yang of the human body, and it is also the focus of qi and blood accumulation and regulation of the whole body.
The ancient navel therapy is to use the special position of navel to treat gastrointestinal diseases, gynecological diseases and other diseases from the navel. Moreover, the stratum corneum in human umbilical region is very thin, and there is a rich capillary network below the umbilical region, and there are depressions in some areas, which is beneficial to the long-term storage of drugs. Through navel administration, the drug can directly enter the blood circulation from the navel and act on the focus, and the drug absorption effect is better.
So navel medication has nothing to do with drinking water. On the contrary, you should drink enough water to lose weight.
