In traditional medicine, practitioners mapped the interconnections in the body through a meridian system. The meridians in the body are a complex system of energetic connections between our organs, and these connections must be open for our body to properly function. By optimizing the function of each organ, and ensuring that the connections between them are unobstructed, vital energy can course along the proper paths and the body is in balance. This is achieved by inserting a needle into various meridian points that are found to be obstructed based on a thorough assessment.
