Our physical traits and characteristics offer deep insight into the health or dysfunction of our body. Signs such as striations in fingernails may indicate mineral deficiencies, cracked skin vitamin deficiency, finger length may indicate hormonal dominance, texture of the tongue organ dysfunction, and so on. When we are clear on what to analyse and know the correlating deficiencies or dysfunctions for these physical signs, then we are able to gain valuable information that can assist us in diagnosing or understanding the state of health of the human body.
