Acute laryngitis often occurs when the throat becomes itchy and coughs after a sore throat. In the early stage of acute laryngitis, the throat becomes congested and edematous, and along with the inflammation there is redness, swelling and heat, so the throat feels more painful. In the later stages, inflammatory exudates are often secreted, and the redness and swelling gradually subside, so the sore throat will gradually disappear. The inflammatory exudate stimulates the throat and makes it itchy, and coughing occurs. The inflammatory cells in the body also shed and become necrotic and mix with the inflammatory exudate to form phlegm, and the stimulation of phlegm also causes coughing. The two drugs are Chinese anti-inflammatory drugs, which have a certain anti-bacterial effect as well as an anti-viral effect, and are particularly effective for upper respiratory tract infections.
