For a chronic cough due to a bad cold or flu, some natural remedies are consuming peppermint tea, honey or bromelain and using a humidifier. Although over-the-counter medications, such as cough suppressants, are frequently used for a chronic cough, honey with warm water can be more effective than using a cough suppressant, states Healthline.
Drinking warm water and honey is a home remedy that is useful, especially when a chronic cough occurs at nighttime. To relieve both a cough and congestion, add lemon to this mixture of honey and warm water. Remedies that contain honey are not for children under the age of 12 months, notes Mayo Clinic.
Peppermint leaves contain menthol, which is useful as a decongestant. Teas made from either marshmallow or thyme leaves can also act as cough suppressants. Based on a research review of pineapple's properties, the enzyme bromelain can also be a cough suppressant, according to Healthline.
Another simple and natural method to treat a bad cough is to utilize a humidifier or take a hot shower. Although these natural remedies may relieve a chronic cough due to a cold or flu, other medical conditions can cause this symptom. See a doctor if a chronic cough last longer than four weeks, notes WebMD.
To treat a chronic cough effectively, it is important to figure out what is causing it, notes Mayo Clinic. Some people who take ACE inhibitor medications may be able to reduce a chronic cough by switching to an angiotensin-receptor blocker. A doctor may recommend decongestants and antihistamines to treat a chronic cough.
For chronic coughs related to asthma, a doctor may recommend an inhaled medication, which widens the airways and reduces inflammation, according to Mayo Clinic. Antibiotics may be an ideal treatment for chronic coughs related to bacterial infections.
If the doctor cannot determine the cause of a chronic cough, he may prescribe cough suppressants, notes Mayo Clinic. Children should not take medications for a chronic cough unless specifically directed by a medical professional.
