Houttuynia cordata Thunb has a special odor. Its leaves and rhizomes can be used as wild vegetables or as medicine. It has the effects of clearing heat, removing heat and detoxification.
Du Mu, a great poet of the Tang Dynasty, saw the Houttuynia cordata in the mountain streams when he was traveling in Xuancheng, Anhui Province. He wrote a poem of "respecting the ash grass, floating light, and hydrolyzing the veins". He lamented that the Houttuynia cordata, once eaten by all the people, is now ignored. He is reminiscent of the past and reminiscent of the present, with a sigh of his own experience. The custom of eating Houttuynia cordata was from Yue State to Wu state, from Wu state to Chu state, and from Chu state to more southern and southwest areas, but it was never introduced into the Central Plains. People in the Central Plains believe that Houttuynia cordata can cause halitosis, and it is a kind of food that people lose etiquette. Only the ignorant Dongyi Nanman would eat it.
Nowadays, Houttuynia cordata grows in Henan Province, but no one eats it at all. Since the gradual "civilization" in Jiangsu and Zhejiang provinces, Houttuynia cordata is no longer popular. As for northerners who have never seen Houttuynia cordata, they often feel nauseous for three days after eating it. Eating Houttuynia cordata is a problem of eating habits. When people in the South eat it for a long time, they don't think it's fishy, but it's delicious. In addition to being used as wild vegetables, the leaves of Houttuynia cordata can also be used to wrap raw fish and slow down the decay rate of fish. In addition, some people use Houttuynia cordata to make pungent soup to relieve the heat. From smell to curative effect, it is quite similar to the current Huoxiang Zhengqi water.
