✵Till the date Oct 10th,2019, there are totally  kinds of common TCM herbs,  kinds of related plant species, are recorded in this category. These Qi Tonics,Herbs for Replenishing Qi are briefly introduced separately:
Rhizoma Polygonati(Solomonseal Rhizome).
Brief Introduction: The herb Rhizoma Polygonati is the steamed and dried rhizome of Polygonatum sibiricum Red., Polygonatum kingianum Coll.et Hemsl., or Polygonatum cyrtonema Hua(family Liliaceae), used (1).to replenish spleen Qi for the treatment of general debility and poor appetite, and (2).to nourish lung Yin for the treatment of chronic dry cough in cases of phthisis.
