The heart yang governs the yang qi of the whole body, and the kidney yang, namely “yuan yang“ , is the innate yang. The two are closely related and are particularly important in the yang qi of the five visceral organs.Heart yang and kidney yang are often damaged in the critical stage of chronic diseases or when diseases prolong for a long period, resulting in heart and kidney yang failure. Curculigo, epimedium and morinda root are commonly used clinically by Academician Tong Xiaolin to reinforce yang, especially heart and kidney yang. Curculigo can invigorate kidney yang, strengthen muscles and bones, dispel cold and dampness, and nourish the fire of life gate, with a common dosage 6-30 g. Epimedium can replenish life gate, nourish vital energy, strengthen muscles and bones, with a common dosage 9-30 g. Morinda root can invigorate kidney and reinforce yang, strengthen bones and muscles, dispel wind and remove dampness, with a common dosage 9-15 g.
