If Chinese herbal medicines sell well, we should be alert that they are fumigated with sulfur

If the sale of Chinese herbal medicines is too good, we should be wary that the Hangzhou food and drug inspection department fumigated with sulfur price will detect the sulfur dioxide residue of Chinese herbal medicines As soon as 10% of them exceed the standard, they will make tea, boil soup and use medicine at the price of wolfberry For Ms Guo who lives in the city, the price of wolfberry has become one of the necessities of their family But since watching CCTV finance and economics "is it true" a few days ago, she has been very confused about whether she can continue to use the price of wolfberry in the future Because the reporter investigation of the program confirmed that the brighter the color of Lycium barbarum is after artificial "make-up", long-term use will hurt the kidney In fact, artificial "make-up" for traditional Chinese medicine has always been a potential industry rule Because after fumigation of sulfur price, Chinese herbal medicines sell well, have heavy weight, and can prevent insects However, yesterday, the reporter learned from the relevant departments that the national pharmacopoeia committee is about to issue a regulation on the limit of sulfite residues (in terms of sulfur dioxide) in medicinal materials and decoction pieces (excluding minerals), which requires no more than 150mg / kg (PPM) The sulfur dioxide residue of ten percent of traditional Chinese medicine exceeds the standard "Sulfur price fumigation of traditional Chinese medicine and Chinese herbal pieces is a common hidden rule, because through this process, traditional Chinese medicine can be bleached, brightened and insect resistant Even the moldy and deteriorated traditional Chinese medicine can be covered up by the method of large amount of industrial sulfur price and repeated fumigation, and the purpose of selling fake and inferior products can also be achieved." Song Xufeng, vice president of Hangzhou food and drug inspection and Research Institute, said Sulfur price will combine with oxygen in the fumigation process to produce sulfur dioxide Sulfur dioxide is a strong reducing agent, which dissolves in water and produces sulfite, sulfuric acid and sulfate, which will destroy the effective components of some medicinal materials and seriously affect the quality and efficacy of medicinal materials At the same time, medical research has proved that the Chinese herbal medicine and food fumigated by sulfur price will damage the digestive tract and respiratory tract system, damage the mucous membrane of these organs and lead to variation; in addition, it will also damage the liver, kidney and other organs In 2009, Hangzhou Municipal Drug Administration selected 8 varieties of Zhebei, angelica and so on for monitoring, and found that the sulfur dioxide residue was generally more than 1000 ppm, the most even more than 2000 ppm According to the national standard to be issued soon, all of them had seriously exceeded the standard During 2009-2011, Hangzhou food and Drug Administration launched the three-year project of non sulfur treatment of traditional Chinese medicine, which aims to supervise the sulfur dioxide residue in traditional Chinese medicine through a large-scale investigation, and take the lead in putting forward the initiative to control the sulfur dioxide residue below 60ppm in the traditional Chinese medicine industry nationwide After rectification, in the first half of this year, Hangzhou food and drug inspection and Research Institute also investigated the sulfur dioxide residue of 76 batches of Chinese herbal medicines (decoction pieces), involving 25 varieties, 7 varieties and 7 batches exceeding the national limit, with a total qualified rate of 90.8%, which is significantly higher than that five years ago "This also means that at present, the sulfur dioxide residue of Chinese herbal medicines in Hangzhou market is relatively reassuring." Song Xufeng said Wang Bin, director of the traditional Chinese medicine room of Hangzhou Red Cross Hospital, is not good-looking at the normal dehydrated traditional Chinese medicine Like song Xufeng, he is also a person who has been dealing with traditional Chinese medicine all the year round When it comes to the issue of sulfur price fumigating traditional Chinese medicine, he feels deeply "Almost at the end of 2009 and the beginning of 2010, many patients caught the medicine and looked so ugly, very difficult to accept, even some people thought we were selling fake medicine and inferior medicine." Director Wang said that in fact, the Chinese herbal medicines after dehydration will not look good without sulfur price fumigation Therefore, if you want to judge whether the Chinese herbal medicines you buy have been fumigated by sulfur price, you can first see the sales volume You should be alert to those with too bright colors, because the prices of yams, Gastrodia elata and Codonopsis pilosula should be light yellow under normal conditions If they are white, they must have been fumigated In addition, you can smell it, pinch it and taste it "The traditional Chinese medicine fumigated with sulfur price usually has a pungent sour taste, which will cover up the natural smell of traditional Chinese medicine; the traditional Chinese medicine fumigated with sulfur price is heavier and softer than the traditional Chinese medicine not fumigated, and the water content can be felt especially when it is kneaded; and the traditional Chinese medicine fumigated with sulfur price usually feels sour at the mouth." Director Wang said.
