The so-called "water needle" is relative to the "golden needle" used in acupuncture. This therapy was founded in the 1950s, when the modernization of Chinese medicine was being vigorously carried out. So many doctors tried to replace the original golden needle with syringe in clinic. Soon, this method was extended to acupoint sealing and many other therapeutic fields. And made great progress.
Because of the use of modern purified drugs, this therapy is different from traditional acupuncture. Because drugs enter the meridians, their treatment rules are different from traditional acupuncture.
But these two therapies are based on the traditional meridian theory. Modern medicine can't explain the meridian theory. Traditional meridian theory can not fully explain and guide modern acupoint injection therapy.
Clinically, "acupoint injection" can treat asthma, Meniere's syndrome, scleroderma, Behcet's disease and other international difficult diseases, especially for gynecological rehabilitation.
Perhaps one day, acupoint injection can become an effective means for Chinese medicine to regain its dominant position in clinic.
