Improved sleep aids in the general healing process, because the body can better fight infection and inflammation when adequately rested.
Pain Relief: Codeine’s analgesic properties help alleviate delicate to moderate pain related with respiratory infections, resembling sore throat and chest discomfort from excessive coughing. By reducing pain, codeine contributes to the overall feeling of well-being and comfort.
