The tongue is the seedling of the mind. Heart governs blood, heart and spirit. The tongue has heart, lung, liver, gallbladder, spleen, stomach and other reflex areas. In the treatment of Alzheimer's disease, in addition to the common original point (the area between cervical vertebra and occipital bone), holographic reflection areas such as the top of the head, hands, feet, eyes, ears and face, as well as spinal massage, tongue massage should also have an effect, but there are few operators. Not only is it effective to massage the tongue, but it is also effective to stretch the tongue every day.
