There are no tricks to cure a cold quickly without medicine. Colds are self-limiting and usually heal themselves in about a week. Colds are generally caused by viral infections such as rhinovirus, adenovirus, influenza virus, etc. They are self-limiting diseases, and patients can usually recover in about a week, and can be effectively relieved by drinking plenty of water, paying attention to rest, and eating a light and easy-to-digest diet. Those diagnosed with influenza can be treated early with oseltamivir antiviral therapy. Symptomatic treatment may be given if necessary, including the use of medications to relieve nasal mucosal congestion and antipyretic and analgesic medications, the former such as ephedrine and the latter such as acetaminophen and ibuprofen. Medications should be used under the guidance of a doctor and should not be used blindly. If cold symptoms persist or even worsen, prompt medical attention is recommended.
