Pineapple contains an enzyme called bromelain, which is considered an effective remedy for cough. Several studies suggest that this enzyme can help to suppress coughs and loosen the mucus in your throat. Pineapple helps relieve sinusitis and allergy-based sinus issues, which often lead to coughing. Besides, it is also sometimes used to treat inflammation and swelling.
Directions: When suffering from a cough, eat a slice of pineapple or drink 250 ml of fresh pineapple juice two times a day. Make sure your fruit and juice are not cold as they may increase the irritation.
