Eating balsam is not recommended when cough symptoms occur. Cough is most commonly caused by inflammatory reactions in the respiratory system, including infectious factors, such as infection by pathogens such as viruses, bacteria, mycoplasma, and chlamydia due to decreased resistance, triggering acute upper respiratory tract infections, bronchitis, and pneumonia. In addition, there are also non-infectious factors, such as stimulation by some allergens, which trigger a hyper-reactive state of the airway, with congestion and edema of the airway mucosa, with contraction and spasm of the airway smooth muscle, and cause coughing. Fragrance oil itself does not contain any anti-inflammatory components, does not contain any antibiotics, and has no coughing or phlegm-relieving effects. When the cough is more pronounced, the viscosity of the fragrance oil may also irritate the airway mucosa and possibly aggravate the cough, so it is not recommended to take fragrance oil. After a clear diagnosis, you should take some Chinese medicines with lung-clearing, phlegm-relieving and cough-suppressing effects as well as corresponding anti-inflammatory drugs. In case of bacterial infection, antibiotics should be used as an option. For coughs caused by allergic reactions, anti-allergy medications should be used.
