The imported Dragon's Blood is processed from the fruit resin of the evergreen tree of the palm family, Eucheuma kirilowii, and other plants of the same genus, while the domestic Dragon's Blood is processed from the resin of the evergreen tree of the semi family Diptera sagittata and the Cambodian Dragon's Blood. It is named "Dragon's Blood" because it looks like dried blood. The original plant of Dragon's Blood in China is 10-20 meters high, with a diameter of 140 centimeters. The xylem of the injured surface is purple red; Leaves are sessile, arrow shaped, leathery and thin; Panicle terminal, globose berry; The flowering and fruiting period is from February to August. Positive tree species. It is distributed in the sunny zone of limestone mountain area south of 23 ℃ north latitude. The products are in various shapes according to different processing, but the powder is purplish red. The efficacy of the domestic dragon's blood is completely the same as that of the imported dragon's blood. It has the functions of activating blood, stopping bleeding, fixing pain, and generating muscles, and can treat various blood diseases. Compendium of Materia Medica calls it "the holy medicine for promoting blood circulation". Historically, China has always relied on imports as one of the important "southern medicine". In 1972, Cai Xitao, the director of Yunnan Tropical Plant Research Institute and botanist, and others first discovered the resource of Dracaena cambodiana in Menglian County, Simao, and named it "Dracaena cambodiana (variety)". This tree became the main raw material source of Dragon's Blood in China later. Cambodia and Laos in Southeast Asia are the main producing areas, Simao and Xishuangbanna in Yunnan are the main producing areas in China, and Guangxi and other places also have some resources. During the general survey of traditional Chinese medicine resources from 1985 to 1990, large areas of pure forests of Dracaena Dracaena were found in Jinggu and other counties in Simao. In order to protect domestic resources, in recent years, a large number of raw materials of Dracaena Dracaena were imported from Laos and other countries for use in the production of Dragon's Blood. From 1982 to 1986, Yunnan Gejiu Pharmaceutical Factory succeeded for the first time in producing domestic Dragon's Blood with Cambodian Dracaena Dracaena Dracaena, and its products were listed in the Yunnan Drug Standards. In 1990, the number of major domestic producers of Dragon's Blood in Yunnan has grown to 6, and the products can basically meet domestic needs.
