At present, there are honey pills, concentrated pills, capsules, granules, drops and oral liquids available for oral consumption. The advantage of these medicines is that they are easy to take and carry, which is suitable for modern life. As the saying goes, “medicine is poisonous in three parts”, if pCms are used incorrectly, they are not good for human body. “evidence”, not “evidence” is not only ineffective but also harmful, such as the cold is a common disease, Chinese medicine to identify the difference between wind-heat, wind-cold, and even “internal heat and external cold” of the special situation If you do not analyze all of them and treat them with Banlangen, it will not be effective and even aggravate the disease. Patients should pay attention to this point if they go to pharmacies to buy drugs for treatment. Nowadays, there are many proprietary Chinese medicines for treating cardiovascular and cerebrovascular diseases. I found that some people only buy proprietary Chinese medicines according to the diseases they suffer from, such as coronary heart disease and sequelae of cerebral infarction, or just listen to the recommendation of pharmacy shoppers without consulting the physician beforehand. If the patient is cold and has Yang deficiency and blood stasis, it is appropriate to use Chinese patent medicines that warm the Yang and invigorate the Blood, but if the patient has Yin deficiency and internal heat, it is definitely not possible to use Chinese patent medicines that warm the Yang and invigorate the Blood. Also, some people like to use intravenous injections of Chinese herbal medicines such as Danshen injection every year as a way of preventive health care, which is an undesirable way and method. Chinese people should learn a lesson from the Japanese Xiao Chai Hu granules incident and not let their bodies make sacrifices for nothing. Finally, how can we use pCms reasonably, I think we should pay attention to do: all the physicians and pharmacists who want to use pCms for patients should consciously study the knowledge of Chinese medicine, so as to have a good idea of what to do, and not to shoot indiscriminately; patients or their families want to use pCms to cure diseases, they must consult with physicians, never think that Chinese medicine has no side effects, pCms can be used at will, to know that the real cure for diseases with the medicine The wrong direction must be harmful, but it is only a matter of big harm and small harm.
