General principles of acupoints and reflecting areas on foot:
According to the meridian theory of traditional Chinese medicine, 6 regular meridians, including--the foot Yangming stomach, foot Taiyang uninary bladder, foot Shaoyang gallbladder, foot Shaoyin kidney, foot Jueyin liver, and foot Taiyin spleen meridians are connected with the foot, and 33 regular acupoints having important therapeutic function are located at the original or terminal parts of these 6 meridians.

Through continuous clinical practice, 74 extra foot acupoints were discovered and put into therapeutic use.

These holographic points and reflecting areas are widely distributed on the foot, produce stable therapeutic effects, and are not difficult to remember and use in clinical practice.

The acupoints and reflecting areas on the hand and foot can be used independently or in combination to produce an adjusting effect anywhere in the body depending on the time and place of treatment, the nature of the disease, and the experience of the practioner.
