The theory of TCM health preservation is extensive and profound, and we have a full understanding of some foods that can be homologous to medicine and food. Many items, such as peels, stones and fruits, which are discarded when we usually eat fruits, vegetables and dried fruits, have good medicinal value in the view of Chinese medicine. If used well, it will effectively promote human health.

Peeling is also good for health.

People eat watermelon, generally only the pulp, and the skin of watermelon is mercilessly thrown away. In fact, the skin of a watermelon can account for about one third.

Chinese medicine believes that watermelon pulp is cold, and eating too much will hurt the spleen and stomach, while watermelon skin, on the contrary, belongs to warm nature. Eating watermelon peel will help protect the spleen and stomach, and its nutritional content is not less than that of melon pulp, but the sugar content of melon pulp is more delicious.

When we eat oranges, many people just eat the pulp and throw away the orange peel. Orange peel, known as dried tangerine peel in Chinese medicine, has the effects of stimulating appetite, promoting digestion and resolving accumulated food. In particular, the orange network on the orange peel has the effect of dredging qi and blood, which is a good product for people's health and fitness. There are many similar peels, for example, the shell of longan can treat skin itching and other diseases, and grapefruit peel has the function of dredging liver qi.

This stone contains more essence.

Among the foods that people often eat, we all eat nuts such as walnuts, almonds and melon seeds, while the nuts of some fruits are usually thrown away and only eat pulp.

Traditional Chinese medicine believes that the stone is the main material for plant reproduction, which contains a lot of genetic material to ensure the growth of seeds, so the nutrition should be much greater than the pulp.

In traditional Chinese medicine, Ziziphus jujuba seed has the function of calming the nerves and is a commonly used medicine for treating insomnia. The longan seed is ground into powder, which can promote wound healing for external use, leaving no scars and eliminating pigmentation. It's good for beauty. Even the wooden things sandwiched between walnuts can be used for soaking in water and drinking, which also has a significant kidney-tonifying effect.

Although the fruit trees are small, they have unique functions.

Fruit should be the most useless in people's eyes. People usually remove fruits or vegetables when they are processed, so as not to affect the taste. In fact, many fruits are used well, which is also a good medicine.

For example, persimmon boiling water can effectively treat hiccups, and it is often a dose of medicine that can be immediate.

Another example is eggplant retort, which is used as an introduction by many folk remedies. People boil water with eggplant retort, which can treat chilblain, promote blood circulation and remove blood stasis.
