The kidney is part of the human urinary system and is responsible for filtering impurities and maintaining body fluid balance. When the kidneys are not good, the body often has symptoms such as fatigue, nocturia, yellow urine, body edema, and decreased appetite. Chinese medicine believes that five fingers connect the meridians of the human body, among which the little finger corresponds to the heart and small intestine meridians, the main kidney system. So, by pointing the little finger, we can see if the kidney is healthy.
