The efficacy of the Seven Needles lies mainly in its unique property of opening the Ren and Du channels. Therefore, it is a rare treatment for patients with complex symptoms, as it often has unexpected effects in treating a variety of diseases. Brief medical history Ms. Guo has suffered from anxiety and depression for many years, often feeling hot and cold, needing to take medication for a long time to sleep and having pain in her breast from time to time. She has tried abdominal acupuncture, head acupuncture and other treatments for two and a half years without any particular success. Treatment effect Tried seven needles, the first time, felt very painful. After taking several points on the back and belly button of the Ren and Du chakras, I felt a warm, spicy state on my body. Each time it lasted for half an hour, and there would be a warm and spicy state several times a day. However, after zapping, sleep problems were significantly improved. It is possible to solve the sleep problem for one night without the support of medication. The second time I zapped, it was a process of draining cold qi, and I felt that my hands and feet were also hot and spicy, with vague cold qi going out from my extremities. After the zapping, spitting began, and after the process of expelling phlegm that lasted for several hours, there was a feeling of excreting body waste. After the follow-up needle tying, it was found that the breast problem was resolved. The area that had been very painful was now only one-tenth as painful. I feel that the problems are being solved one by one, and I am very grateful to have met Dr. Duo. In this case, it is very important that the Seventh Path is directed at the Ren and Du meridians, especially the circulation around the spine: by opening the meridians around the spine, the Qi and blood can be better regulated and the body can be brought back into balance. The balance of the spine can better drive the recovery among the five internal organs and bring back the healthy state. The brain and nervous system can also be nourished and the effect on depression can be significantly improved with a smooth flow.
