Kidney Yang is also known as the Life Gate or the Lower Burner or Fire of your body. It can also be viewed as your basal metabolism and at times referred to as the Ming Men. The Kidney Yang is responsible for vitality, action, food and water metabolism, assertiveness and libido. Deficient Kidney Yang may show with such patterns as asthma conditions, urinary incontinence, fatigue, impotence, anemia, excess urination, cold lower back and legs or general bodily coldness, abdominal and lower extremity water retention, hypertension and a weak lower back. Deficient Kidney Yang can usually, but not necessarily always, be found with the elderly.
