Lung-clearing tea becomes popular in hazy days

　　During the continuous haze days, many pharmacies launched the "Haze Qingfei Recipe" composed of five traditional Chinese medicines. The public generally recognized it and found it to be beneficial and harmless. Some pharmacies said that this kind of prescription is a hot seller when winter comes. However, traditional Chinese medicine experts say that such prescriptions are not very effective, and citizens should "prescribe the right medicine" based on their own physical conditions. For haze days, protection is more important.

　　The same prescription has different prices

　　Yesterday, a Beijing Morning News reporter visited a number of pharmacies and found that many Chinese herbal medicines with lung-clearing effects are favored by the public. At the entrance of a chain drugstore famous for its Chinese herbal medicines, a "Haze Qingfei Prescription" is posted in a conspicuous place, which contains five Chinese medicinal materials, including Luo Han Guo, lily, plum blossoms, money grass, and apocynum.

　　The staff of the pharmacy said that the prescription was prepared by experts from the Traditional Chinese Medicine Hospital to combat the smog. “It is available in all its pharmacies and has been selling very well these days. The main function is to clear the lungs and moisturize the lungs, and has the effect of removing inhalable haze particles." In addition, the other party told reporters that the preparation of traditional Chinese medicine is the same as making tea. All the medicinal materials can be brewed with boiling water. “Take once a day and can drink it repeatedly. ”

　　In addition, reporters saw traditional Chinese medicine teas with the keyword "anti-smog" at the entrance of many pharmacies. The ingredients of the prescriptions were the same as above, and the dosages were basically the same. However, the price of each dose of "medicated tea" ranges from 5 yuan to 20 yuan in different pharmacies.

　　At a drug store located in the North Fourth Ring Road, a staff member said: "We can't get this prescription today. Let's come back the day after tomorrow." After asking, the reporter learned that due to the large number of buyers, the Luo Han Guo in the prescription was "out of stock."

　　Mr. Sun, a citizen, came to the drugstore and bought 10 doses at a time. He said, "These medicines are all good for moistening the lungs. There will definitely be no harm in drinking them."

　　Physical protection is more important

　　As for the effectiveness of "Haze Qingfei Tea"? The reporter consulted Dr. Wu Zhuboring, an expert in traditional Chinese medicine at Beijing Hospital. Dr. Wu told reporters that Chinese medicine pays attention to "symptomatic" when prescribing medicine. Doctor Wu said that the ingredients of "fog" are mostly water vapor, "and the lily and Luo Han Guo in the above prescription have the effect of clearing away heat and moisturizing the lungs, and are more suitable for relieving lung heat and dryness caused by dry environments. If the air humidity is sufficient, there is basically no need to 'moisten the lungs'. It is more important to use tangerine peel, Sichuan Fritillary and other methods to 'remove dampness and reduce phlegm' and cough up the harmful substances in the lungs."

　　In addition, in Dr. Wu’s opinion, although several herbs in the prescription can indeed moisten the lungs and clear phlegm, their use must be adjusted according to the external environment and one’s own constitution. “The five herbs are basically cold in nature and are not suitable for people with cold bodies.” Moreover, the "apocynum" in the prescription is commonly used in antihypertensive drugs, which has some toxic and side effects and is not suitable for everyone.

　　Finally, Dr. Wu also said that the effects of traditional Chinese medicine are mostly auxiliary. "It's hard to say how effective it is." For the current haze weather, physical protection is more important. "Reducing outdoor activities and wearing good quality protective masks when going out are effective ways to reduce the entry of harmful substances into the lungs."
