Anti-inflammatory effect: Taxus contains a lot of tannin, which has antibacterial and anti-inflammatory effects. It not only has therapeutic effect on upper respiratory tract inflammation, but also has remarkable curative effect on nephritis, gastritis, enteritis, adenomyosis and rheumatoid disease. It can be used externally to treat dermatitis and beriberi. [In Dictionary of Traditional Chinese Medicine, Flora of Chinese Medicinal Plants, Forest Records of China, Compendium of Materia Medica].
Health care efficacy: According to the fact that the water extract of Taxus chinensis contains a lot of alkaloids and high-activity taxol, Tianjin Health Care Products Co., Ltd. has developed Taxus chinensis Health Care Cup and Taxus chinensis Health Care Tea (diabetes tea, pharyngitis tea, dysmenorrhea tea, etc.). ) and successfully put it on the market.
Ecological value: Taxus media-Lvxing 1 has the characteristics of developed lateral roots, rapid growth and strong adaptability to the environment, which can be widely used to build soil and water conservation forests and is the first choice for national key ecological construction projects.
Gardening value: Its unique appearance and bright green all year round can be seen in the United Nations Headquarters in new york, in front of Buckingham Palace in Britain and the White House Square in the United States.
Indoor bonsai media-Green Star 1 are mostly shrub-like, with lush foliage. Various artistic shapes such as circle, umbrella and tower can be formed by manual pruning. Because it has lived on the earth for more than 2.5 million years, it is called "the sacred tree of geomantic omen" among the people.
Economic value:
At present, medicinal taxol mainly comes from wild yew, but the global yew resources are very limited, with a total of about100000 plants. According to the research of American yew researchers, even if all the yews in the world are cut down and used to extract paclitaxel, only 1.25 million lives can be saved. Because of this, the current international price of paclitaxel per kilogram is as high as more than 300,000 US dollars. (journal of traditional chinese medicine, China, July 2002 1 1 reported).
The last line of defense for advanced cancer: The clinical experiment of National Cancer Institute (NCI) shows that paclitaxel extracted from the endothelium, roots, branches and leaves of Taxus chinensis is considered to be the best anticancer drug in the world after adriamycin and cisplatin in recent fifteen years. It is an efficient, broad-spectrum, best-selling and hottest new anticancer drug in the world, and it is also the last line of defense for advanced cancer, which has extremely high medicinal development and utilization value.
About 6.3 million patients worldwide die of cancer every year, and about 4 million in the United States, Europe and Japan alone. The treatment of these patients consumes about 2,200-4,600 kilograms of paclitaxel every year, while the world can only produce about 320-500 kilograms of paclitaxel every year, of which the United States can produce 35-50 kilograms and China can produce 50 kilograms (mainly for export). Therefore, it is necessary to cultivate and plant Taxus chinensis artificially on a large scale.
To protect Taxus chinensis var. pendula, the United States banned all logging in order to protect Taxus chinensis var. pacifica, which had few resources, which led the United States, Europe, Japan and other regions to come to China to buy the skins, branches and leaves of Taxus chinensis at high prices. On March 3, 2003, CCTV's "Focus Interview" column reported the case of illegal logging of Taxus chinensis in Lijiang, Yunnan Province, which attracted the attention of the whole country and caused the devastating logging of Taxus chinensis resources in Yunnan. Therefore, the state has specially promulgated the Taxus resource protection law.
Taxus chinensis-the "tree of hope" for conquering cancer: Taxol has been approved as an anticancer drug by more than 40 countries, including the United States, China, Britain, France, Japan, Italy, Canada, Sweden, Germany, Norway, Denmark, Finland, Switzerland, Austria and Australia, and has special effects on treating breast cancer, stomach cancer, colon cancer, rheumatoid arthritis and psoriasis. So far, for a long time to come, the most favorable weapon for human beings to fight cancer can only be paclitaxel. Therefore, yew is called the "tree of hope" to conquer cancer at home and abroad.
