Yam is sweet and flat, and enters the spleen, lung and kidney. It has many functions, such as invigorating spleen, tonifying lung, strengthening kidney and benefiting essence. Along with Achyranthes bidentata, Rehmannia glutinosa and Chrysanthemum, it is known as the "Four Great Huai Medicines" and sold overseas, and it is said that "Huaishan is the first of the four Huai Medicines, and the iron bar of Huaishan family is king". Using yam with other ingredients in spring has a good effect of invigorating spleen and eliminating dampness.

The simplest way is to wash and cook directly. Because of its low water content and rich polysaccharide content, its juice is thick, which will not be dispersed after being boiled for a long time, and its taste is sweet and waxy, accompanied by a faint hemp taste, and it will produce saliva in the mouth after eating for a short time.

2. Fungi

Fungi are also a good ingredient for eliminating dampness. Fungi include all kinds of ears and mushrooms, such as auricularia auricula, tremella, mushrooms and dictyophora. Fungi are rich in protein, dietary fiber, amino acids, vitamins and minerals, and at the same time, they are free of cholesterol, low in fat and sugar.

There are hundreds of kinds of wild fungi, but few of them can be eaten. Besides natural reasons, the pollution of the growing environment can also cause poisoning of consumers. It is imperative to identify toxic wild mushrooms in time. Generally, we should be cautious about wild mushrooms with bright colors, erythema, pungent odor and bitter taste, and stay away from them, but edible mushrooms have fragrance and no odor.

3. Smilax glabra

According to Compendium of Materia Medica, Rhizoma Smilacis Glabrae has the functions of "strengthening spleen and stomach, strengthening bones and muscles, and expelling wind and dampness". Fresh Rhizoma Smilacis Glabrae not only has the effect of eliminating dampness and detoxifying, but also is fresher in taste than dried Rhizoma Smilacis Glabrae.

The general practice of Smilax glabra is to decoct medicine or soup, which can be combined with pork with nourishing yin and moistening dryness in spring. It is not advisable to drink a lot of tea after eating pork to prevent tannic acid in tea from combining with protein to generate astringent tannic acid protein, which will slow down intestinal peristalsis and cause constipation and increase the absorption of toxic substances.

4. Wax gourd

Maybe many people don't know that winter melon is not only a vegetable we eat every day in summer, but also a kind of Chinese medicine, which has the effect of benefiting water and eliminating dampness.
