Euryale ferox is the dried and mature seed kernel of Nymphaeaceae, also called "chicken head rice" and "chicken head", which is more common in the south. Traditional Chinese medicine believes that Euryale ferox is sweet, astringent and flat, which can strengthen the spleen and eliminate dampness, strengthen the kidney and stop diarrhea, and has the advantages of "nourishing but not strong" and "preventing dryness and not greasy". Its effect of tonifying kidney is better than that of yam, eliminating dampness is better than that of adzuki bean, and calming heart is better than that of lotus seed. It can be said that it is a buried tonic. Su Dongpo, a great writer in the Song Dynasty, lived by eating gorgon fruit.
Chestnuts. Sweet chestnuts are very popular snacks in autumn and winter, and are rich in nutrients such as sugar, protein, fat, vitamins and minerals. Chinese medicine believes that chestnuts are sweet and warm, and have the effects of nourishing stomach and strengthening spleen, tonifying kidney and strengthening tendons.
Peanuts. Peanut is a high-protein oil crop, which has enjoyed the reputation of "longevity fruit" since ancient times. "Compendium of Materia Medica" records that "peanuts like spleen and stomach, moisten lung and eliminate phlegm, replenish qi and nourish yin, clear throat and relieve itching", which is suitable for people with spleen deficiency, emaciation, less food, dry cough and less phlegm. It is worth noting that peanut red coat (that is, peanut coat) is more effective in invigorating qi and stopping bleeding. Therefore, people who need blood can choose small peanuts with more red clothes, and people who cook porridge and beat peanut pulp can choose big peanuts. In addition, soaking peanut kernels with vinegar and boiling water with raw peanut shells have certain antihypertensive effects.
