Drinking lotus heart tea may have the benefits of clearing the mind and calming the nerves, but brewing the tea and drinking it may not be able to fully precipitate the active ingredients of the drug so that the efficacy is effective. Lotus heart is the dried young leaves and embryonic root tea from the mature seeds of lotus in the water lily family. Bitter flavor, cold nature. Attributed to the heart and kidney meridians. It has the effects of clearing the heart and tranquilizing the mind (stabilizing the mind by getting rid of inner vexation and heat), communicating with the heart and kidney (fire in the heart descends and water in the kidney rises, restraining each other), and astringing semen and stopping bleeding. Lotus heart can be used for heat entering the pericardium (heat evils invading the pericardium), delirium tremens (delirium, babbling), failure of the heart and kidneys to communicate with each other (heart fire, kidney yin deficiency, and dysfunction of the physiological functions of the heart and the kidneys), insomnia with spermatorrhea, and hematemesis and vomiting of blood with blood heat. Drinking Lotus Seed Heart Tea can clear the heart and calm the mind, and can be used to regulate heartburn, insomnia and other conditions. A single lotus seed heart tea has limited effect. It is recommended that patients be treated with medication under the guidance of a doctor, and do not use medication on their own.
