Sea cucumber is a warm tonic. "Compendium of Materia Medica" records that sea cucumber is sweet and salty, tonifying kidney and essence, promoting diuresis and strengthening yang, treating flaccidity, and being warm and nourishing, so it is named sea cucumber. Sea cucumber has the functions of improving memory, delaying gonadal aging, preventing arteriosclerosis and resisting tumor. Sea cucumber is rich in nutrients such as protein and calcium, while fruits such as grapes, persimmons, hawthorn, pomegranate and olives contain more tannic acid. Eating at the same time will not only coagulate protein, but also cause abdominal pain, nausea, vomiting and other symptoms.
