What is the skin of tangerine peel? Chenpi is the skin of oranges in fruits, and the dried body is called Chenpi. Pericarpium Citri Tangerinae is widely used in clinic, which is suitable for some patients with abdominal distension, diarrhea, abdominal distension, excessive phlegm and cough, especially for respiratory tract infection and some old phlegm. Common diseases are chronic bronchitis and obstructive emphysema. These diseases occur all the year round, and each attack has a lot of phlegm, which can be treated with dried tangerine peel. In addition to resolving phlegm, dried tangerine peel can also strengthen the spleen, which has a very good effect on anorexia, dyspepsia caused by spleen deficiency and nausea and vomiting caused by gastritis. It is best to apply dried tangerine peel under the guidance of a doctor.
Chenpi, also known as orange peel, was called "Gui Lao" and "Red Peel" in ancient times. It is the pericarp of small evergreen trees in Rutaceae and the mature fruit of many plants of the same genus. Because the fresh peel is spicy and the orange peel with a long aging time is better, Guangdong Xinhui orange and Chazhi orange have the best peels, so the prescriptions of traditional Chinese medicine often write "GuangChenpi" and "Xinhui Peel".
Although fresh orange peel and dried tangerine peel are the same thing, their properties are quite different. Fresh orange peel contains more volatile oil and does not have the medicinal effect of dried tangerine peel. However, after the second year, the content of volatile oil in dried tangerine peel will be greatly reduced, and the content of flavonoids will be relatively increased. At this time, the medicinal value of dried tangerine peel can be reflected. In addition, because the surface of fresh orange peel is polluted by pesticides and preservatives, these chemicals are harmful to human health, and soaking it in water may also have adverse effects on health.
What is real dried tangerine peel? First of all, origin:
For dried tangerine peel, the place of origin is the most important. There are many producing areas of dried tangerine peel, including Guangxi, Guangdong, Fujian, Chongqing and Hunan. Among them: Guangxi, Hunan and other places have large output, and Guangdong News Agency produces the best dried tangerine peel, so most of the good dried tangerine peel is the best. At the same time, Xinhui Chenpi is a national geographical indication protection product.
Second, the year:
The true year's tangerine peel is thin, the color will be unevenly distributed, and the pores in the oil cavity of the skin are evenly and densely distributed, with obvious concave-convex feeling. For more than ten years, the inner cortex of dried tangerine peel will loosen and fall off slightly, and the smell will produce new fragrance with the increase of years because of the volatile oil, which will gradually change from the sour taste of fruit to the unique fragrance, aging and mellow of dried tangerine peel.
In artificial years, the pericarp of dried tangerine peel is thick and the color is not naturally formed. After artificial soaking, coloring and drying, the color distribution will be uniform, the size of skin oil pockets will be different, and the concave-convex feeling is not obvious. For more than ten years, the pericarp of dried tangerine peel is dense and smooth, and there is no shedding phenomenon. Because of the lack of a year, the smell does not have the pure peel fragrance unique to a real year.
