Earth remedies have no scientific basis and cannot be used to treat colds. Colds can be categorized into common colds and influenza, both of which are acute upper respiratory tract infections. The common cold is often caused by rhinovirus, coronavirus, adenovirus and other infections, with nasal congestion, runny nose, fever, cough and other symptoms. Influenza is caused by influenza viruses and has more severe symptoms, mainly high fever, aches and pains, fatigue and other systemic symptoms. For virus-induced colds, there is a lack of effective treatment drugs, and symptomatic measures are mainly taken. Antiviral drugs are generally not needed for common colds, while influenza requires early use of antiviral drugs such as oseltamivir. If there are symptoms such as nasal congestion and runny nose, ephedrine drops can be given; if the dry cough is severe, cough suppressants can be given. If dry cough is severe, cough suppressants such as dextromethorphan can be given; if sputum is abundant, sputum removing drugs such as bromhexine can be given. If there is a basis for secondary bacterial infection, antibiotic treatment can be used, commonly used cephalosporins such as cefdinir, ceftazidime, cefradine, and penicillin amoxicillin, or azithromycin macrolides. If the symptoms of cold and flu are more serious, it is recommended to consult a doctor in time, and use medication under the guidance of the doctor, so as not to delay the condition.
