Oranges cannot relieve cough and resolve phlegm.
Cough and phlegm are caused by primary diseases such as pharyngitis, bronchitis, pneumonia, tuberculosis, bronchiectasis, lung tumors and so on. Oranges can neither treat the primary disease, nor by inhibiting the cough center (central cough), or by reducing the sensitivity of the respiratory tract sensory nerve endings to stimuli (peripheral cough) and cough effect.
The treatment of cough and sputum caused by different primary diseases is different, for example, cough and sputum caused by Streptococcus pneumoniae, need to follow the doctor’s instructions to use antimicrobial drugs, such as penicillin, ceftriaxone and other anti-infective treatment; cough and sputum caused by tuberculosis need to follow the doctor’s instructions to give rifampicin, isoniazid and other treatments.
If you have a cough and sputum, you need to go to the hospital to find out the cause of cough and sputum and actively treat it, it is not recommended to eat “oranges” method of treatment.
