The flu is an illness that almost all of us cannot avoid. It is called upper respiratory tract infection by many viruses and bacteria in Western medicine, and “typhoid” in Chinese medicine. In addition to influenza, many people suffer from colds mostly due to excessive internal fire, which is triggered by wind and cold when the resistance is low. Internal fire can be caused by over-eating spicy food, or overworking, staying up late, or being a “Yin deficiency fire” body; low resistance often occurs after excessive physical work or labor, or you are a soft and flabby subhealthy quality. In this case, you can catch a cold with a little wind and cold. After a cold, many people do not take it seriously and consider it a minor illness often take the approach of “hard resistance” to treat, which is not wrong for those who are usually healthy; however, for those who are sub-healthy, allergic, or have a low fever or cough for a long time after a cold, we should be alert to the occurrence of rheumatic fever to avoid heart valve disease (i.e. rheumatic heart disease), arthritis, myocarditis and other diseases. Myocarditis and other diseases. Because many of these diseases belong to allergic immune diseases of synovial membranes in the body caused by streptococci, they are slowly progressive diseases that affect the health of life. Therefore, we recommend that active treatment should be taken after a cold, and the treatment should be given first and foremost to Chinese herbal medicine. It is better not to take Western medicine to reduce fever if you can, because the side effects of these drugs are too great, especially for the affected children, and should be used with caution. Chinese herbal medicine in the treatment of colds, by relieving symptoms and clearing heat, balancing yin and yang, can quickly alleviate the condition; for the sub-healthy can also improve their immune system; after a long period of coughing and spitting up phlegm after a cold through clearing lung heat, cough and phlegm, not only can quickly stop coughing and eliminate phlegm, while the low fever is also cured. What is even more gratifying is that the side effects of Chinese herbs are minimal!
