[Body Detoxification] The lymphatic system is an important part of the human immune function. It can remove waste, toxins and pathogens from the body. Lymph flows continuously in the body, throughout the body. The lymphatic system is not as good as the blood circulation system and can rely on the beating of the heart to help flow. Therefore, passive massage is needed to stimulate the lymphatic system throughout the body. It must be performed by a professional masseur who understands the structure of the lymphatic system to ensure the effectiveness and safety of the massage.
