It turns out that this sunflower is the oldest vegetable in the past, and all the five dishes mentioned in Huangdi Neijing are headed by it. Sunflowers can be planted all year round, and can be divided into spring sunflower, okra and winter sunflower according to the harvest season. As for whether there are anemones, it is still unknown. Therefore, in ancient times when vegetables were scarce, sunflower was a very important vegetable for the ancients. As soon as Chinese cabbage appeared, sunflowers gradually became notorious. Chinese cabbage tastes better and is more hardy than sunflower. Su Shi once said that eating cabbage in winter is more delicious than eating mutton.
Sunflowers can also be seen in the countryside, especially on the roadside, beside the courtyard wall and in the grass in the fields. Sunflower soup tastes slippery, and now many old people still love to make soup. In fact, as a wild vegetable, it has another health-preserving effect.
Sunflower can resist cold, and its coldness can clear lung and relieve cough, which can be used to treat lung-heat cough, especially for some people with wind-heat cold, pneumonia cough and yellow pus.
Modern people's diet is often too spicy and greasy. Many people suffer from various enteritis, frequent stomachache and indigestion. Sunflower is a very light food, cool in nature, which can clean the intestines and play the role of clearing heat and diminishing inflammation. Sunflower has a good effect on enteritis and dysentery, and such patients may wish to eat more sunflower.
The elderly will be constipated in nine cases out of ten due to the dissipation of essence and lack of middle qi, which is very painful. At this time, another great effect of sunflower can be brought into play. Sunflowers contain soft and slippery substances, which can lubricate the intestines, make the large intestine unobstructed, and constipation naturally disappears. Therefore, sunflower, a wild vegetable, is still very suitable for the elderly.
