I don't know what a cashew tree looks like. Today, I'm going to introduce something about Yaoguoshu.
First, the basic information of "Medicine Credentials"
In plant taxonomy, Cynanchum auriculatum belongs to the evergreen shrub or small tree of Cashew, also known as chicken cashew, _ Rushu.
Originated in the northeast of Brazil, it was introduced to tropical countries and regions in Asia, Africa and South America in the16th century. It is one of the four famous nuts in the world. Cashew nuts were introduced to Hainan Island, China in the 1940s. After 1960, the seeds imported from Sri Lanka were tried in Guangdong, Hainan, Guangxi, Yunnan, Fujian, Jiangxi and Sichuan provinces. Later, due to the out-of-control cold damage, it was successfully introduced only in Hainan Island and Xishuangbanna, Yunnan Province. After 1973, seeds were introduced from Tanzania and planted in Guangdong, Hainan and Yunnan. Hainan alone planted 13333 hectares, mainly distributed in six counties in the south and southwest of Hainan, mainly producing Ledong County. From the mid-1980s to the early 1990s, cashew production in China ushered in the third development peak. During the period of 1984- 1990, the Institute of Tropical Crop Variety Resources of Chinese Academy of Tropical Agricultural Sciences, the Hainan Cashew Research Center and the Royal Tropical Research Institute of the Netherlands cooperated to carry out the "Hainan Cashew Development" project, which further expanded the planting area of cashew nuts in China and enriched the germplasm resources.
