Honey is a time-honored remedy for a sore throat. According to a 2007 study, it can also relieve coughs more effectively than over-the-counter medicines that contain dextromethorphan (DM), a cough suppressant.
You can create your own remedy at home by mixing honey with herbal tea, or warm water and lemon. The honey does the soothing, while lemon juice can help with congestion.
Probiotics are microorganisms that can provide a host of health benefits. While they don’t relieve a cough directly, they help to balance your gastrointestinal flora (the bacteria that live in your intestines). This can support immune system function throughout the body. Some evidence also suggests that Lactobacillus, a bacterium in dairy, can reduce the likelihood of a cold or flu, and sensitivity to certain allergens like pollen.
Fortified milk is a great source of Lactobacillus.You should be cautious, however, as dairy may make phlegm thicker.
You don’t usually think of pineapple as a cough remedy, but that’s probably because you’ve never heard of Bromelain. According to a review of research on the medicinal value of pineapples, there is evidence to suggest that Bromelain — an enzyme found in the tropical fruit — can help suppress coughs as well as loosen the mucus in your throat.
There are also claims that it can help relieve sinusitis and allergy-based sinus issues, which can contribute to coughs and mucus. However, there is insufficient evidence to support this, according to the National Institutes of Health (NIH). It’s also sometimes used to treat inflammation and swelling.
Bromelain supplements should not be taken by children, or adults who take blood thinners. Also, be careful using this if you are also on antibiotics such as amoxicillin as it can increase the absorption of the antibiotic. Always speak to your doctor before taking new or unfamiliar supplements.
