Based on a meridian system that can be understood as energetic channels coursing throughout the body. Specific points along these channels help to govern the flow of energy. When these channels become blocked, disease is allowed to set in and produce characteristic symptoms.
The nature of disease is particularly evident through the characteristics of one's pulse and tongue, both of which are assessed to confirm a diagnosis. In order to correct this underlying cause of disease, the channels are unblocked via stimulation of specific points (according to the type of disease, diagnosis) that govern the flow of energy along the channels.
Stimulation is typically achieved by inserting fine needles into the skin and underlying tissue, but also through the use of suction cups.
