Officinal plant resource overdraws to fa

"The licorice of our country north sufferred disaster, be mopped up of licorice ' licorice main forces ' , from northeast 3 provinces could there be to pleasant of short for Shaanxi Province, go to Inner Mongolia again, dig Xinjiang all the time, approach border. Traverse the licorice area that boreal border visits each, together piece be eliminated, leave the close jumping pit that is as deep as a meter many everywhere, be just as the battlefield after a disaster that suffer misery.

Be just as the battlefield after a disaster that suffer misery..



A day of dusk, yang Jun hill teachs as usual to take regular bus to come home. When grade of 10 thousand coins heads division of Haidian of by way of, he discovers surprisingly, in the trade tree that plants in road both sides, the skin of a few the bark of eucommia is pared get 708 chaos. See this situation this scene, this old professor that played a few years to be handed in with officinal plant times feeling is distressed.



"This kind of decorticated means, to the bark of eucommia character, it is annihilative blow simply! " Yang Jun hill is Chinese academy of medical sciences the researcher of officinal plant institute, he says, the good tree that the bark of eucommia is urban afforest not only is planted, its bark is material of our country's peculiar rare Chinese traditional medicine more. The experiment proves, be in only appropriate period, adopt correct cricoid decorticate law, just make naturally of the bark of eucommia produces new skin likely.



Regard a country as rare live thing of 2 class endangered precious, in last few years, the amount of resource of the bark of eucommia is dropping quickly.



Guizhou, it is one of country of origin of the bark of eucommia, already can face the crisis that the bark of eucommia eradicates nowadays. Chinese traditional medicine of institute of Guiyang traditional Chinese medical science institute director He Shunzhi, once spent time field of 6 years to investigate, looked for Guiyang churchyard, fail to find feral the bark of eucommia from beginning to end however.



Our country has Chinese traditional medicine resource 12807 kinds, front row ranks on the world. However, material of our country commonly used Chinese traditional medicine is at present medium, the breed of 70% is supplied rely on feral resource, year quantity of total demand exceeded 600 thousand tons.



The current situation that overdraws badly makes experts of many doctor of traditional Chinese medicine very afraid. Because of the basis 1983 statistical data, 11146 kinds of Chinese traditional medicine use a plant in, total reserves of feral medicinal material is 8.5 million tons, even if the home is planted medicinal material, produce per year a quantity to also do not cross many tons 30. And reflect this rate, expend talent of 12 million tons of Chinese traditional medicine 20 years at least.



Make a person more of angst is, the people of a few places, it is cost in order to do death of individual plant floral, lumber draw materials sells directly. The method of kill the goose that lays the golden eggs, make our country original resource of not much feral and officinal plant drops quickly. Expert estimation, our country is used in iatrical plant, a variety of 3000 plant destinies got browbeat, a lot of sort are sufferring the disaster that eradicate, include a few commonly used Chinese herbal medicine.



Having " the king of numerous medicine " the licorice that say, it is one kind is by praise highly " the state is old " plant. It fights cold, heat-resisting, still fight salt alkaline, adaptability of it may be said is extremely strong. But it also joined the range that is protected nowadays in.



"The licorice of our country north sufferred disaster, be mopped up of licorice ' licorice main forces ' , from northeast 3 provinces could there be to pleasant of short for Shaanxi Province, go to Inner Mongolia again, dig Xinjiang all the time, approach border. Traverse the licorice area that boreal border visits each, together piece be eliminated, leave the close jumping pit that is as deep as a meter many everywhere, be just as the battlefield after a disaster that suffer misery. " the experience that Peng Hua of researcher of institute of plant of Kunming of Chinese Academy of Sciences describes licorice so.



According to national regulation: Licorice 3 years of growth period, the ability when growing a diameter to reach 0.8 centimeters for 0.6 centimeters can be collected dig. And a few " licorice main forces " no matter licorice size, all unplug its even the root, add in successive years excessive collect dig, the feral licorice of and other places of Shaanxi, Shanxi, Gansu Province already was close to eradicating.



Inner Mongolia past is licorice all the time advocate producing area, from last centuries 70 time begin, as a result of licorice can collect an amount gradually acute is decreased, make feral licorice advocate produced an area to transfer Xinjiang; However the foreground that Xinjiang produces a division also nots allow hopeful.



Peng Hua says, 20 centuries 50 years early days, region of oasis of border of north and south is licorice everywhere, it is precious medicinal material not only, still remove windbreak solid sand at the same time, protect the action of edaphic vegetation. But, teemed with licorice in the past and static, with and other places of lake of over sixty years of age of large, Yan, rich, licorice shows disappeared already.



Such menace affected Chinese traditional medicine be servinged as is used already had 5000 historical magnolia. This kind of plant contains chemical composition and phenol of the bark of official magnolia, and Chinese traditional medicine is used and phenol of the bark of official magnolia treats cancer, and the fit of slow down heart disease. The Chinese traditional medicine that the bark of official magnolia is protection of our country key material, review what its come nearly 40 years to live destiny, make a person sob indeed.



Peng Hua tells a reporter, the beautiful water district of Zhejiang south is the tradition with our country the greatest the bark of official magnolia produces a division. Last centuries before 60 time, this land is wild the bark of official magnolia is wide to distributing; Arrive on century 70 time, because this area large area builds fir commercial forest, major the bark of official magnolia is mixed unripe forest suffer fell trees, distributinging limits of feral the bark of official magnolia decreases quickly, output falls quickly also; Going up century 80 time, get the drive of market interest, local Lin Nong pectoral diameter the tree of the bark of official magnolia of 10 centimeters of above digs even the root light almost, resource sufferred annihilative destruction; Arrive on century 90 time, this area already looked for less than becoming a community of feral the bark of official magnolia. Current, plant of feral the bark of official magnolia is very scarce already, it is to help advance somebody's career artificially mostly.



The reality that cannot be in severe danger to causing Chinese herbal medicine artificially again overlooked!



"Once feral and officinal plant is eradicated, we cannot be done feral the comparative experiment that plants with the home, also cannot give out scientific number will prove they wait for a respect to have what distinction in medical effect, gene. " Yang Jun hill says, feral and officinal floral disappears will affect diversity of our country biology, mean gene of feral and officinal floral feral Chinese traditional medicine of our country of will permanent vacancy gene library.



Our country ancient time is famous " on the partisans is joined " eradicating is one typical case. According to Introduction Zhang Zhao, on the history a lot of a book on Chinese medicine account ginseng " give birth to party and distant east " . Classics textual research, "On party " show Shanxi is long treat He Licheng to be taken, "Distant east " show northeast grows Bai Shan area. "The partisans is joined on " discovery and application all antedate " ginseng of long Bai Shan " , but dig through counting acting plunder type to collect, and a large number of deforest, changed zoology environment, to bright generation " on party ginseng " already eradicated.



Nevertheless Yang Jun hill emphasizes, should prohibit absolutely people is collected dig feral and officinal plant, both neither is desirable impossible also. So, have method to be able to allow feral and officinal plant " those who take is endless, those who use not exhaust " ?



The expert thinks, "Become feral to be planted for the home " it is the positive step that rescues these is close to that eradicate species. To this, zhang Zhao of researcher of officinal plant institute says Chinese academy of medical sciences, will satisfy the market to need through helping advance somebody's career artificially, ability from go up at all alleviate the pressure of pair of feral resource.



However also the viewpoint thinks, help advance somebody's career artificially the medicinal material replaces feral medicinal material completely, way is very long still. Bookstall of association chairman house says Chinese Chinese traditional medicine, had been not solved up to now like the commonly used medicinal material such as Xue Lian, aweto or solve completely feral change a planted problem.



In addition, although at present establish of type of work of person of a few commonly used and officinal plants gains ground, but because some artificial and officinal plants mutate big, hold original genetic characteristic and active ingredient very hard, its are officinal value sells at a discount greatly.



"Make clear Hunan our country has how many kinds of precious after all material of rare endangered Chinese traditional medicine, it is the fundamental premise that protects finite biology resource effectively. " Yang Jun hill says. However, from 1983 up to now, our country also did not understand Chinese traditional medicine again the family property accumulated over a long time of resource. The expert thinks, urgent affairs should build Chinese traditional medicine namely resource database.



Current, our country already included national wild plant to protect directory (the first batch) officinal plant has 20 a variety of, include " be in severe danger convention of international trade of the species that use plant (CITES) " the officinal plant of the appendix has 30 to plant (kind) . As we have learned, academy of Chinese traditional Chinese medical science is building Chinese precious now rare be in severe danger officinal plant database, there are a variety of 50 Chinese traditional medicines at least nowadays put in storage.



Zhang Zhao thinks, effectively protective precious is rare be in severe danger officinal plant, a large number of hard works want to do, in short-term inside can not have distinct effect. For example, build precious rare be in severe danger library of officinal floral gene, undertake collect and be protectived on the base that must undertaking extensive field is investigated. In addition, a species is close to eradicating, besides factitious explicit element, existing toward contact the immanent cause with progenitive oneself, should find out the element that send danger and trying to solve is a long-term course.
