Taxus chinensis belongs to shallow-rooted plants, with inconspicuous main roots and developed lateral roots. It is a rare natural anticancer plant recognized as endangered in the world. It is an ancient tree species left over from Quaternary glaciers, and has a history of 2.5 million years on the earth. Due to the slow growth rate and poor regeneration ability of Taxus chinensis under natural conditions, a large-scale raw material forest base of Taxus chinensis has not been formed in the world for a long time. From 65438 to 0994, Taxus chinensis was designated as a first-class rare and endangered protected plant in China, and it was also called "national treasure" by 42 countries with Taxus chinensis in the world. The United Nations also prohibits logging, which is a veritable "plant giant panda".
