Home remedies for coughing include increasing fluid intake to moisten mucus membranes, taking steamy showers to loosen congestion and drinking warm liquids, such as hot water with honey, to relieve throat irritation, explains WebMD. Running a humidifier in the home can also soothe coughs caused by allergies and asthma.
Studies have shown that bromelain, an enzyme naturally found in pineapple, breaks up mucus in the throat and suppresses coughing attacks when taken in supplement form, according to Healthline. However, anyone who takes medications to thin the blood should not take bromelain supplements. Peppermint tea can also soothe throat irritation and loosen throat mucus. While coughing can often be remedied at home, seek medical attention if coughing lasts more than three weeks or is accompanied by a fever.
