Drugstore medicine wears the dimension C Yin Qiao that go up piece
As a kind of medicaments that is written into pharmacopoeia, even if be in memory of ordinary common people, of vitamin C famous degree very tall. Cite a simple case, yothe most popular selling norton internet antivirusu may not know dimension C Yin Qiao piece medium " amino to acetyl phenol " and " Ma Lai is acerbity chloric benzene Na Min " waiting for medicaments is why content, had not heard of vitamin C impossibly however.
However, hong Kong explodes recently Yin Qiao of C giving dimension piece contain " ban drug " incident, touched the nerve of people, this incident is confirmed to was to place Wu Long, make the same score the misgive of people mind hard up to now however, also caused the attention of deeper administrative levels.
If explain hot demulcent part " amino to acetyl phenol " with what can relieve n&v snuffle symptom " Na Min of chloric benzene of Ma Lai acid " just be to be able to alleviate the brunt of cold symptom, why should that add vitamin C in patulin? What disease can vitamin C treat after all? Have why side-effect?
Accepting southern daily reporter when exclusive special interview, guangzhou medical university is accessary medicine of the 3rd hospital learns department head apothecary to manage Tu Bing says, the cold is below most circumstance be restricted what cause by virus oneself sexual disease, if do not have other basis disease or infection of intercurrent bacterium sex, drink more water, much rest, can be not treated and heal, vitamin C rises to alleviate only the effect that the n&v snuffle when the cold spreads tears symptom and the strength that increase pair of infection. Meanwhile, the vitamin C that tastes the market to be popular in health care can not eat casually actually, long-term large dose is used can cause undesirable effect instead.
Dimension C and cold
Bao Lin is opposite winner of two nobel prize, famous academic chemist vitamin C have the greatest esteem for, but multinomial researfree modern dining chairsch shows, occurrence cold symptom just begins to take vitamin C, with take comfort an agent about the same
True perhaps He Baolin is concerned, vitamin C just can get attention so. Go up century 70 time, he promotes vitamin C in numerous circumstance, say to be able to prevent and cure cold, cancer, heart disease, still can fight consenescence, caused a pursuit in the United States even " natural health is hot " .
Allegedly, him Bao Lin is daily take C of 12000 milligram vitamin at least, if appear cold symptom, he is met take dosage to promote 40000 milligram, once appear,claim to catch a cold take after the symptom, have magical effect, "Feel suddenly mental day fine, also did not catch a cold " .
Because Bao forest reputation is celebrated, about 50 million person joins fanaticism to go after vitamin C thisi want modern dining chairs one " health care is tasted " in cavalcade, make its sale rises sharply, the price rose 3 times, still demand exceeds supply.
Although Bao Lin's view gets ordinary people chase after ardently hold in both hands, did not get medical bound and nutrient academia all the time however approbate. Management board of American food medicines and chemical reagents also offers criticism to Bao Lin's words and deeds, think large-scale " dimension C is hot " absurd absurdity. The expert thinks, evaluate the effect that medicaments prevention and cure catchs a cold, need has the clinical trial of big sample book, use contrast randomly method in group, with observation of double blind law, the experience of the feeling of Chan Ping's individual and small number of people, cannot make objective judgement.
Different point of view, let vitamin C and cold even more " worry " . Can vitamin C treat a cold after all? The scientist developed a series of clinical trials.
Harri Hemila, Elizabeth Chalker, Bob Douglas ever was in online on July 18, 2007 publish a paper " Vitamin C For Preventing And Treating The Common Cold " (" the vitamin C precaution to common cold and cure " ) . 3 Australian scholars did the test that treats common cold about vitamin C, covered eleven thousand three hundred person in all. Among them, 29 are compared group examined " cold duration " , the cold of 9649 person-time is come in to analyse by include, the result shows, preventive give vitamin C to have to adult and child shorten the effect of course of diseases, the adult can shorten the course of diseases of 8% , the child can shorten the course of diseases of 13% ; And the experiment series that just begins to take vitamin C in occurrence cold symptom, with take those who comfort an agent to contrast group do not have apparent difference.
Still have on the network first such information: Blame seek profits the researcher that cooperation of international of constituent division Ke Lun organizes is right 30 multinomial in all the research that 11 thousand person participates undertook statistic and analysis, conclude: To Everyman, take cold of vitamin C prevention and cure to do not have any effects, catch a cold to prevent and cure and take many vitamin C to be done not have completely necessary.
Complete beauty turns over Stephen of vice-chairman of wholesome and con committee, M.d.·Baleite ever also expressed publicly, whether does the action thnorth face shirtsat vitamin C cure catchs a cold have actual application value to return existence controversy, because of the rehabilitation that the doctor thinks this meeting decelerates a cold.
FDA of management board of American food medicines and chemical reagents also points out: "Shang Moke learns evidence, and the intention that can show without important research vitamin C has prevention and cure to catch a cold.
If use clinical trial speech, conclusion looks be like lean to one side. To this, guangzhou medical university is accessary medicine of the 3rd hospital learns ministry associate professor Dr. Xia Chenglai to think, the viewpoint that medical science studies be patient of is different exists at the same time, but the point of view that shows Bao Lin without evidence of abide card medicine at present is correct.
Dimension C treats a disease
Fall in condition of certain pathology physiology when human body, to vitamin C absorb, absorb be not worth or vitamin C is used up, excrete and demand grow in quantity, need additional complement right now
And no matter vitamin C after all whether treat a cold, to most person character, it is " good thing " .
Our country Ceng Yi spends therapeutics of C of vitamin of faddish large dose. Till today, the teacher of a few college of medicines of domestic still lively ground is told about " spoon of Bao Lin give oneself airs eats vitamin C piece " story; A lot of people catch a cold to be able to take the 1 vitamin C bubble that overcomes to vacate piece; Be in a few days ago, the author says to be bitten by the mosquito to drugstore, the salesperson promotes vitamin C bubble none hesitantly to vacate piece, say to be able to enhance strength.
And actually, the decisive therapy effect of vitamin C has nothing to do with the cold however, treat scorbutic —— however this kind of disease absorbs be caused by of insufficient, diarrhoea, vomiting for a long time by vitamin C, can cause vitamin C shortage, make collagen albumen cannot be synthesized normally bring about cellular coupling obstacle, blood capillary brittleness increases, cause the haemorrhage below skin mucous membrane thereby.
200 old before, of the trade of abroad and expeditionary, trade as European country and colonial dilate arisen, oceangoing voyage develops quickly. And scorbutic to Yuan Hang person, more terrible than rainstorm and experience pirate. 1747, limejuicer doctor Zhanmusi·Lynd is right maritime suffer from scorbutic bluejacket to undertake experimental therapy, the result proves orange and lemon juice show surprise effect, and Lynd also is considered as medical history C of aspirant travel vitamin is clinical the pioneer of the experiment. Confirm later, the fruit can be treated scorbutic because it contains vitamin C,be.
What is vitamin C after all? How effective is it?
" pharmacopoeia of People's Republic of China " and " make up materia medica newly " such description: The vitamin is one of element of 6 big nutrition that human body preserves normal metabolization and functional place to need, vitamin C regards a kind of water-solubility as the vitamin, participate in human body a variety of oxidation are reductive synthesis of reaction, material and alexipharmic function, at the same time it can reduce blood capillary fully gender, combat histamine and the strength that increase pair of infection.
"Accordingly, fall in condition of certain pathology physiology when human body, to vitamin C absorb, absorb be not worth or vitamin C is used up, excrete and when demandwatch cases grow in quantity, be opposite for example scorbutic cure, disease of path of bowel of all sorts of urgent chronic contagion, stomach, cardiovascular disease if when the danger such as myositis of Keshan disease, heart weighs a diseasnorton internet antiviruse to undertake assisting cure, need C of additional and compensatory vitamin. " Si Tubing explains further, to the cold character, most circumstance because its itself is be restricted what cause by virus oneself sexual disease, if do not have,contract other basis disease, drink more water, much rest, need not be treated and heal, the action that reachs since vitamin C amid, more is auxiliary reduce n&v snuffle, symptom drifting tears and the strength that enhance to be affected to virus.
"Especially the person is when the cold is calorific often have a poor appetite, vitamin C is absorbed mediumly from food, absorb inadequacy and consume grow in quantity, it is OK proper additional. Special to pregnant woman, should choose carefully in gestation when other patulin is treated to disease, compensatory vitamin C can be a safer choice. " Si Tubing says.
Dimension C causes disease
Healthy person takes C of vitamin of more than 1 gram to be able to send acerbspring poolity heighten of blood in the urine everyday, have the risk that causes gout, and American newest research makes clear, excessive takes vitamin C to may quicken arteriosclerosis
Bao Lin's story has not been told.
1994, the enthusiastic hunter of this vitamin C dies at prostate cancer, die at the age of is 93 years old, he insists to think vitamin C already deferred the happening of cancer 20 years to death, although this cannot test and verify. He still has said, "Eat a vitamin to C can prevent and treat the cancer of 75% alone " . Nevertheless people discovers very quickly, alleged vitamin C lengthens cancer to live the conclusion of time is to be based on impertinent statistical analysis.
Allegedly, bao Lin's student and assistant A a twenty-five-stringed plucked instrument·Abdicate doctor returns Robin to discover in the experiment, what he recommends is daily the 5 odds that let small white rat contract skin cancer to dosage of C of 10 grams vitamin increase one times, nevertheless, he reports to fire suffers unexpectedly after this result to Bao Lin, experimental animal and data all by destroy by melting or burning.
In the idea of a lot of people, take vitamin C security tall, won't have side effect, accordingly need not dispute dosage, even somebody is far from fine when taking vitamin C several, grab at random a few in putting an import.
undeserved take vitamin C to you still can cause disease?
Xia Chenglai expresses, from the point of clinical angle, if not have,complement blindly vitamin C, all regard excessive as. He one by one fine the side-effect that counted healthy person to take C of vitamin of more than 1 gram to may arise everyday: Acerbity heighten of blood in the urine has the risk that causes gout; Hematic oxalate and heighten of acerbity salt of half Guang ammonia and forming secrete make water is calculous; Cause the gastric bowel function such as countercurrent of grow in quantity of hydrochloric acid in gastric juice, gastric juice, abdominal distension, diarrhoea disorder; When long-term large dose applies, stop drug suddenly easy bring brass faucetabout the vitamin C chroma inside body to drop abruptly, can cause scorbutic clinical performance, if appear,purpura of gum haemorrhage, skin and heart function are damaged; American newest research makes clear, excessive takes vitamin C to may quicken arterial sclerosis to wait.
Not only such, the BBC reported a newses 2009, an American research of research center of cancer of Ji Teling of Si Luoen — shows, and not by the Xiaobai of infuse vitamin C rat photograph is compared, a series of anticarcinogen thing are right by infuse the power of the cancer cell inside the Xiaobai mouse system of vitamin C decreased 30% to 70% . The test changing cure that has ever since also discovers, by infuse the cancer cell inside the system of small white mouse of vitamin C grows faster; And another research discovery, vitamin C can disturb the curative effect of 5 kinds of anticarcinogen contentharrison hot spring deal, your cancer cell grows rapidder.
Visible, c of excessive complement vitamin may do not have advantage harrison hot spring weather forecastnot only, still can have disadvantage even.
Manage Tu Bing reminds, should not regard vitamin C as nourishment or cordial and do not add limitative ground to use. "Rich natural vitamin C is contained in fresh vegetable and fruit, if food is reasonable, do not have special need again, the vitamin C that normal person absorbs from inside food everyday, can satisfy daily need commonly, without necessary and additional complement. " she still expresses, the work of vitamin C humanness that buys in drugstore or hospital synthesizes a product, far on the effect be inferior to natural vitamin C, "The natural vitamin C that contains in fruit, vegetable helps play action jointly through ascorbic acid and rue glucoside, answer to eat some of fresh vegetable and fruit more so, regard a vitamin as the main source of C with this, and do not complement in great quantities blindly nutrient preparation.
