Have you heard that the Japanese have medical treatment based solely on the fingers? Yes, actually each finger is connected to at least two organs.

This treatment is based on hand’s fingers, especially the important points of the fingers which can balance all the energy in the body which from other hand is important for physical and emotional health of your body.

How it works:

To act on some organs just take finger with the other hand and hold it firmly for three to five minutes. You have to breathe in deeply after the massage of each finger of both hands. You should use about three minutes on each finger.
