5 Natural Cough Home Remedies
People use a range of natural remedies to try to treat a persistent cough. Here, we look at 5 of these remedies in more detail.
1. Honey tea
A popular home remedy for coughs is mixing honey with warm water.
According to some research, honey may relieve coughs.
A study on treatments for nighttime coughing in children compared dark honey with the cough-suppressing medication dextromethorphan and with no treatment.
The researchers reported that honey provided the most significant relief from coughing, followed by dextromethorphan.
Although the benefits of honey over dextromethorphan were small, parents rated honey most favorably of all three interventions.
To use honey to treat a cough, mix 2 teaspoons (tsp) with warm water or an herbal tea. Drink this mixture once or twice a day. Do not give honey to children under 1 year of age.
Staying hydrated is vital for those with a cough or cold. Research indicates that drinking liquids at room temperature can alleviate a cough, runny nose, and sneezing.
However, people with additional symptoms of a cold or flu may benefit from warming up their beverages. The same study reports that hot beverages alleviate even more symptoms, including a sore throat, chills, and fatigue.
The symptom relief was immediate and remained for a continued period after finishing the hot beverage.
Hot beverages that may be comforting include:
- clear broths
- herbal teas
- decaffeinated black tea
- warm water
- warm fruit juices
A wet cough, which is one that produces mucus or phlegm, may improve with steam. Take a hot shower or bath and allow the bathroom to fill with steam. Stay in this steam for a few minutes until symptoms subside. Drink a glass of water afterward to cool down and prevent dehydration.
Alternatively, make a steam bowl. To do this, fill a large bowl with hot water. Add herbs or essential oils, such as eucalyptus or rosemary, which may also relieve decongestion. Lean over the bowl and place a towel over the head. This traps the steam. Inhale the vapors for 5 minutes. If the steam feels hot on the skin, discontinue until the skin cools down.
People with a wet cough or chest congestion may also wish to follow the recommendations of the National Heart, Lung, and Blood Institute (NHLBI) and use a cool-mist humidifier or steam vaporizer in their home.
Ginger may ease a dry or asthmatic cough, as it has anti-inflammatory properties. It may also relieve nausea and pain.
One study suggests that some anti-inflammatory compounds in ginger can relax membranes in the airways, which could reduce coughing. The researchers mainly studied the effects of ginger on human cells and animals, so more research is necessary.
Brew up a soothing ginger tea by adding 20–40 grams (g) of fresh ginger slices to a cup of hot water. Allow to steep for a few minutes before drinking. Add honey or lemon juice to improve the taste and further soothe a cough.
5. Salt-water gargle
This simple remedy is one of the most effective for treating a sore throat and wet cough. Salt water reduces phlegm and mucus in the back of the throat which can lessen the need to cough.
Stir half a teaspoon of salt into a cup of warm water until it dissolves. Allow the solution to cool slightly before using it to gargle. Let the mixture sit at the back of the throat for a few moments before spitting it out. Gargle with salt water several times each day until the cough improves.
Avoid giving salt water to younger children as they may not be able to gargle properly, and swallowing salt water can be dangerous.
