There is no evidence that roasted oranges have a cough suppressant effect. Although the orange peel concocted from the Chenpi, orange red, etc. has a certain effect of phlegm and cough, but it is more difficult to use alone to play a therapeutic effect. Oranges as a fruit, roasted oranges to eat part of the orange flesh rather than the real can be concocted as a medicinal material of orange peel, the original does not have a therapeutic effect, in the roasted and can not be used as a drug. The peel also loses its medicinal properties after roasting and cannot be consumed or used as a medicine. Cough has many causes, such as bronchitis, tuberculosis, lung tumors, reflux esophagus disease, acute left heart failure and other diseases, we need to clarify the cause of the disease, for the cause of the treatment, such as bronchitis, use antibiotics, and then symptomatic treatment, the use of cough medicines, such as carboxymethister granules, licorice tablets and so on. It is recommended that people with coughs consult a doctor in time, under the guidance of a professional doctor for treatment, do not self-medication.
