Generally speaking, cough syrups have various effects and functions such as relieving exterior symptoms and clearing heat, resolving phlegm, alleviating cough, improving sore throat and swelling, and promoting sputum expulsion. The details are as follows:
1. Relieving exterior symptoms and clearing heat: Cough syrups contain ingredients such as Bupleurum (Chai Hu), Lonicera flower (Shan Yin Hua), Kudzu root (Ge Gen), and Forsythia (Lian Qiao), which possess properties that relieve exterior syndromes and clear internal heat, thereby achieving the effect of dispelling exterior pathogens and reducing heat.
2. Resolving phlegm: Cough syrups also contain components like Scutellaria (Huang Qin), Platycodon (Jie Geng), and bitter apricot seed (Ku Xing Ren) that help resolve phlegm, thus providing an expectorant effect.
3. Alleviating cough: Cough syrups include ingredients such as licorice root (Gan Cao) and Artemisia annua (Qing Hao) that have antitussive properties. After administration, they can suppress excitation of the cough center and relieve cough symptoms.
4. Improving sore and swollen throat: Cough syrups contain moisturizing components that lubricate the respiratory tract, helping to relieve throat discomfort caused by dryness.
5. Promoting sputum expulsion: After taking cough syrup, patients may experience mild irritation to the respiratory mucosa, which can stimulate secretion and facilitate the expulsion of phlegm.
If patients need to use cough syrup, it is recommended to do so under the guidance of a physician to avoid overdose and potential harm to the body. After taking cough syrup, patients should avoid drinking water immediately, as this may dilute the medication and reduce its effectiveness. During treatment, patients are advised to maintain a light diet, drink plenty of warm water, and ensure adequate rest to support recovery.
