In the clinic often encounter treatment of excessive or low menstrual flow patients, gynecological treatment is generally endocrine therapy, some patients have concerns about hormone therapy, then we look for an acupuncture point on our body – blood sea, since the ancient physicians named it blood sea point, it must be related to blood. By analogy, of course, it is closely related to women’s menstruation. “In terms of blood, the Spleen meridian is responsible for the proper functioning of blood in your body. And the Sea of Blood is an acupuncture point on the Spleen meridian, so its function is actually responsible for how much blood you bleed. If you have too much menstruation, then you should look for the Blood Sea point on the left side. If the menstrual flow is too low, then you should look for the Blood Sea point on the right side. The treatment is as simple as swinging your fist or knocking with a small health hammer (preferably a rubber hammer). If you have a heavy period, knock on the left side of the Blood Sea point, and if you have a light period, knock on the right side of the Blood Sea point. Each knocking time is unlimited, but the total time of each knocking day should not be less than one hour, preferably more than two hours, for at least one month. If you bleed a lot, you can use the palm of your hand for an hour, often with immediate results.
