The application of antiviral drugs is limited by the large number of types of cold viruses, their constant mutation and the inability to diagnose them in a timely manner, resulting in a lack of targeted treatment. Therefore, Western medicine still treats colds mainly by symptomatic treatment. Chinese medicine has a very unique effect in the treatment of colds. Chinese medicine believes that the cold is a common external disease caused by touching the wind, according to the evidence can be divided into: 1, wind-cold evidence: the main manifestations of the cold, fever light, no sweating, headache, pain in the limbs, nasal congestion, sound heavy, sometimes runny snot, sore throat, cough, sputum thin white, mouth not thirsty or thirsty like hot water, thin white tongue coating and moist, pulse floating or floating tight. The treatment is based on pungent warming and relieving the symptoms, with prescriptions such as Jing Fang Defeat Poison San with addition and reduction. 2, wind-heat evidence: the main manifestations of the body heat, slightly evil wind, sweating and diarrhea is not smooth, head swelling and pain, cough, sputum sticky or yellow, dry throat or throat moth red swelling pain, nasal congestion, runny yellow mucus, thirsty to drink, tongue coating thin white slightly yellow, side tip red, pulse floating number. The treatment is to cool the surface with pungency, with prescriptions such as Yin Qiao San and Onion and Black Bean and Mandarin Tang plus or minus. 3, summer heat and dampness: seen in summer, body heat, slightly evil wind, little sweat, dizziness and swelling, aching limbs, cough, sticky phlegm, runny nose, disturbed heart and thirst, or sticky mouth, thirsty and not drinking, chest tightness and generalized evil, short urine and red, thin yellow and greasy tongue coating, moist pulse. Treatment: To dispel the heat and relieve the symptoms of summer heat. Therefore, if you have a cold, go to the hospital in time and let the doctor treat you according to the evidence. Avoid improper use of medicine. And herbal treatment must be early to have a better effect. But most people think that the cold is a minor disease, often self-medication, and self-medication process often exists more misconceptions: 1, a cold on the taking or injection of antibacterial drugs: according to statistical analysis, patients with upper respiratory tract infections using antibiotics did not shorten the course of the disease, and can not prevent the occurrence of pneumonia, and repeated use of antibacterial drugs will cause the body’s resistance to decline and lead to the production of drug-resistant bacteria. Most colds are caused by viruses, and it is only necessary to give antibacterial drugs when secondary bacterial infections (peripheral blood picture and/or neutrophils accounted for by Billy significantly increased). 2, the simultaneous application of a variety of drugs, or do not understand their own situation random medication: the treatment of a wide range of cold drugs, and most of the compound preparations, some Chinese medicine with Western medicine, if the simultaneous use of more than two cold drugs may lead to repeated overdose of certain drug components, can cause serious adverse drug reactions, resulting in damage to body function. For example, some drugs contain ephedrine, such as excessive intake, hypertension, hyperthyroidism, glaucoma, prostate enlargement, coronary heart disease patients and its dangers, engaged in driving, working at height or operating precision instruments workers do not take anti-cold drugs containing chlorpheniramine maleate, benadryl. Therefore, before using the drug must understand the composition and characteristics of the drug. 3, slightly fever and cough with antipyretic drugs and cough medicine: fever and cough is the body’s normal defensive reaction, below 38 ℃ body temperature is not harmful to the body, and facilitate the clearance of the virus, taking antipyretic drugs and hormone therapy, easy to weaken the body’s defensive capabilities. It is advisable to drink more water when the fever is low, and physical cooling is the mainstay. If the body temperature exceeds 38℃, then give antipyretic treatment. The human body expels phlegm through coughing, which at the same time reduces the invasion of viruses and bacteria. If cough suppressants are used, the cough reflex is suppressed, resulting in the inability to eliminate secretions and further aggravation of infection or spread of infection to the lower respiratory tract, especially in patients with chronic respiratory diseases. Only when the dry cough affects sleep can be given cough medicine. 4, children’s colds, adult drugs into small doses fed to children: colds are common childhood diseases, about 1/3 of parents choose their own drugs for their children, which is more dangerous, because children’s organs are in the growth and development stage, more sensitive to drugs, the composition and dose of drugs have strict requirements, children taking adult drugs can not guarantee the dose of drugs and restricted ingredients. 5, hard to carry on not to see a doctor: survey data show that only 7.9% of cold patients choose to see a doctor, the proportion is low. There are 23.22% of people who ignore the cold and choose to “carry on”. Since the cold is a self-limiting disease, for young people, if they can tolerate headache, fever, runny nose and other symptoms caused by the cold, “carry” on a few days can indeed be self-healing, but prolonged delay may delay the disease, and even lead to myocarditis, nephritis, etc.. And the elderly have a cold, you can not “carry”. They are in poor health, organ lesions are more likely, the body functions are weakened, such as symptoms are not treated in time, it is easy to induce complications, serious and even life-threatening. In addition, there are a variety of early manifestations of diseases similar to the cold, such as lymphoma, pneumonia, rhinoceros, mumps, allergic rhinitis, measles, etc., so do not take the “cold” is not a disease, timely medical treatment and timely dialectical treatment to ensure good health.
