Lotus heart and dendrobium can be taken together in an infusion. The two will not produce drug conflict, but the drug infusion can not give full play to the efficacy of the drug, can not fully play a therapeutic role. Lotus heart is the dried young leaves and embryonic roots from the mature seeds of the lotus plant of the water lily family. It has the efficacy of clearing the heart and tranquilizing the mind (by removing the inner heat to stabilize the mind), transporting the heart and kidney (heart fire down, kidney water up, mutual restraint), astringent spermatozoa and stopping bleeding, and is clinically used for delirium tremens (delirium tremens, gibberish), insomnia and spermatorrhea, and blood heat and vomiting of blood and other illnesses. Lotus heart is bitter and cold, cold people need to be careful. Dendrobium is the fresh or dried stems of the cultivars of Dendrobium officinale, Dendrobium bulbosum or Dendrobium tasselum of the Orchidaceae family and its similar species of the same genus. It has the effects of benefiting the stomach and generating fluids (nourishing the stomach by replenishing the fluids in the stomach), nourishing yin and clearing heat (nourishing the yin essence and clearing heat). Dendrobium is often used in the treatment of dry mouth and thirst, gastric yin deficiency (insufficient yin fluid in the stomach), dry vomiting with little food, deficiency heat after illness, yin deficiency and fire (deficiency of yin essence in the body and hyperactive fire), bone vapor and labor heat and other diseases.
