What is the scientific name of Pinus densiflora?
Taxodiaceae: Taxodiaceae.
Alias: yew, cypress
Genus: Taxus chinensis
Taxus chinensis, also known as yew, also known as Pinus densiflora. This is a shallow-rooted plant. The taproot is not obvious, and the lateral root is developed. It is recognized as a rare and endangered natural anticancer plant 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.
PACLI TAXEL, an extract of Taxus chinensis, has a unique anticancer mechanism. Dr. BRODER, director of the National Cancer Institute of the United States, said that paclitaxel is a new anticancer drug with better efficacy and less side effects after adriamycin and cisplatin in recent 15 years. Since 1980s, the United States, Britain, Russia, South Korea and China have conducted in-depth research. The United States took the lead in applying the research results to medical clinic and achieved remarkable clinical results in the treatment of various cancers. Since then, mankind has made new breakthroughs in the field of anti-cancer. So far and for a long time to come, one of the most favorable weapons for human beings to fight cancer is paclitaxel.

Taxus cuspidata is suitable for planting in north and south. It has the characteristics of liking shade, drought tolerance and cold tolerance. The soil PH is required to be 5.5 ~ 7.0, which can be interplanted with other tree species or orchards. Management is simple. Among them, Taxus cuspidata is an ancient tree species left over from the Quaternary Glacier, which has survived on the earth for more than 2.5 million years under harsh climatic conditions. It not only has developed lateral roots, lush foliage and strong germination, but also adapts to a wide range of climate, requires wide soil quality, and is resistant to pruning, cold and insect pests. But also can grow into towering trees, and some plants can even grow for thousands of years, which can be used as medicinal varieties and green varieties.

[Edit this paragraph] The origin of this name
Plants such as Taxus chinensis have become hot stars in the plant world in recent years. Because paclitaxel can be extracted, it is an internationally recognized anticancer agent and a national first-class protected tree species. The red beans of Taxus chinensis are the same as the acacia beans in the south, and they are red outside and bright inside, which can support people's acacia. Taxus chinensis is also named after the same fruit as red beans, so it is named Taxus chinensis.
