Where does the precious southern medicine Amomum villosum belong?

Amomum villosum produced in Yangchun is the authentic Amomum villosum in China, which belongs to Xiangzhen medicinal materials in the south of China. "China Pharmacy Dictionary" records: "Amomum villosum is full and compact, while other Amomum villosum is dry, flat and thin, with a light smell." Amomum villosum is an evergreen herb of Zingiberaceae, which grows in the shade and is 3 feet high. Its branches and leaves are very similar to those of ginger. Amomum villosum has a characteristic: the flowers on the branches do not bear fruit, but the flowers on the stems that spread on the ground bear fruit. Flowers bloom in March and April, white as jade. The fruit was born in June and July, pink and prickly, slightly larger than Amomum villosum. It is the most famous Jinhua Pit in Panlong, Fucheng. According to legend, before people knew Amomum villosum, Amomum villosum was a wild plant. One June, many cattle in Panlong died of dysentery because there was no medicine. However, the cattle in the village near Jinhua pit are safe and sound. People feel strange, so they go up the mountain with cows to see what is going on. When I came to Jinhuakeng, I saw a plant similar to ginger growing under the trees on both sides of the ditch. From these "wild ginger", there is a strong pungent smell. The cattle came here and stopped to drink enough water before leaving. People taste the pit water, and it smells good. So I think this kind of thing is a good medicine for dysentery, which is to collect branches, leaves, roots and fruits and cook them for cattle. It really works. It works as soon as you take it. The news spread, people not only went to Jinhua pit to collect "wild ginger" to cure cattle disease, but also dug it back and planted it in the Woods. In this way, year after year, Amomum villosum becomes more and more valuable. It is said to be a tribute from the emperor. Nowadays, Amomum villosum is everywhere in Yangchun, and a Amomum villosum experimental station has been set up in the city to study and cultivate with scientific methods and promote the development of Amomum villosum planting. Amomum villosum is sweet, sour, bitter, spicy and salty, and flowers, fruits, roots, stems and leaves can be used as medicine. Since the Tang Dynasty, there have been records about Amomum villosum in all previous dynasties. "Kaibao Materia Medica", "Compendium of Materia Medica" and related dictionaries say: "Amomum villosum, a ginger plant, is warm in nature, pungent in taste, and has the functions of harmonizing middle warmer, activating qi, harmonizing stomach and invigorating spleen, and is mainly used for treating chest tightness, food stagnation and choking." Amomum villosum not only has magical effects, but also is a good condiment. A plate of fish, steamed with a grain and a half of Amomum villosum, overflowed the restaurant with fragrance. According to the characteristics of Amomum villosum, the recipes such as Amomum villosum, spring sand chicken, spring sand fish and spring sand soup transferred by Yangchun Food and Beverage Department have a unique flavor and are deeply appreciated by tourists. Yangchun Winery also uses Amomum villosum as the main raw material to produce Chunsha wine and Chunhua wine. The wine is pure and fragrant, moist and soft, rich in nutrition, expelling wind and promoting blood circulation, invigorating spleen and regulating stomach, and regulating dampness. It is one of the best wines in Guangdong. There are also "spring sand honey", "spring sand sugar" and "spring sand preserves", all of which are memorable foods. The flowers, leaves, stems and roots of spring sand and tea are brewed into "Amomum villosum tea", which is more fragrant and delicious than ordinary green tea and beneficial to body and mind. It would be a great pity if people who come to Yangchun don't drink a cup of "spring sand wine" or "spring sand tea"
