It is not recommended to eat Cordyceps sinensis when a cough occurs. Cordyceps sinensis is a particularly tonic herb that is helpful in strengthening the immune system. However, during a cough and cold, tonic herbs are not recommended and simple, light and easily digestible foods need to be used for treatment. And the cause of the cough needs to be found for targeted treatment. For example, if a cough caused by a respiratory infection occurs, appropriate antibiotics or antiviral drugs need to be selected for anti-inflammatory treatment according to the type of infection. For example, you can use busulfan for antiviral treatment and cefaclor granules for antibacterial treatment. It is also best to use cough expectorants such as pulmonary cough combination and tranylcypromine oral solution. However, if a long-term cough occurs and the body is weak, it is possible to take Cordyceps to enhance the body’s immunity and replenish the strength.
