Colds are not difficult to treat, but many readers do not know how to treat colds, which leads to spending more money without curing the disease and leaving endless troubles. In February, I saw 70-year-old Mr. Zhang, who had a recurring cold for half a month and had a fever for 3 days when he came to see the doctor. After inquiring to understand that he had a cold this half a month, first used a cold punch, ceftazidime capsules, cough and other symptoms disappeared 3 days after the cough and other cold symptoms. Later, he used Chinese medicine, after which his cough decreased, but he had fever, sweating, dry and itchy pharynx, dry cough, little sputum, no appetite, and fear of cold, etc. He was diagnosed as having a spleen disorder. After diagnosis, Mr. Zhang was suffering from spleen qi deficiency, stomach fluid deficiency, liver wood multiplying the spleen, and concomitant depressed heat and external wind-cold, I gave him medicines to strengthen the spleen, benefit the stomach and promote the production of fluids, to disperse heat from the liver and evacuate wind-cold. On a recent follow-up visit, Mr. Zhang did not have another cold. As we grow older, our yang energy declines, and our yin essence gradually weakens with the decline of yang energy. Colds in the elderly are often not purely caused by wind-cold or wind-heat, but are often accompanied by a deficiency of positive qi. At this time, the treatment of cold and flu can not be used alone to dispel wind-cold or wind-heat method, and must be fixed to protect the positive qi, especially to protect the spleen and stomach as the first priority. Reminder: 1, the elderly cold carefully use cold punch, cold spirit and other general cold medicine, must pay attention to whether there is a deficiency of positive qi, otherwise, it will lead to the positive qi more weak, more prone to colds. 2, whether it is the elderly, or young people, colds should be distinguished from wind-cold or wind-heat. For wind-cold colds, cold medicines cannot dispel wind-cold, but only reduce the symptoms of colds. The use of pungent and warm to relieve the surface of the Chinese medicine and Gua Sha, fire cupping (from the cervical vertebrae points, along the middle of the spine with 3 to 4 cans, 15 minutes after the start of the can, continuous plucking for 2 to 3 times), serving ginger, scallion and white radish soup are a good choice for the treatment of wind-cold cold, simple, practical and inexpensive. For wind-heat colds, the effect of Vitamin C tablets is good. 3, after the cold carefully use anti-inflammatory drugs. Viral colds are not suitable for antibiotics, even if it is a bacterial cold, can only be used for a short period of time with the appropriate antibiotics. Anti-inflammatory drugs are mostly cold in nature, and improper application can easily damage the body’s yang qi, especially the yang qi of the spleen, which leads to phlegm and dampness, and a lack of source of qi and blood biochemistry, which will result in all kinds of residual discomforts after the cure of a cold.
