Itchy cough is a common cough after a cold, also known as subacute cough. Patients mostly have an irritating dry cough or a small amount of white mucus sputum, which can last for 3-8 weeks or even longer. The cough is more frequent before going to sleep and in the morning when waking up. Routine blood tests are often normal. These patients are often misdiagnosed as suffering from Lonichiasis, because 90% of them are viral infections, so the treatment with antibacterial drugs is not effective. Some patients can take 1-2 capsules of Asmec for temporary relief of itchy throat. It is more effective when combined with Chinese medicine. Patients with itchy throat and cough should pay attention to abstaining from eating fried, deep-fried and spicy foods. Eat less beef, goat, chicken, fish, goose, seafood, longan and lychee during the onset of the disease. Suspend smoking and alcohol, and avoid staying up late and straining. Chinese herbs can be decocted again or more often as tea. For some patients, coughing is aggravated when lying down, so you can raise the pillow appropriately.
