Natural Relief for a Sore Throat
Slippery Elm, Honey, and Pectin
Some natural remedies are thought to work by providing a soothing coat to the throat. Such products include honey, pectin, and slippery elm. All three of these natural products are found in many different commercially available throat lozenges. Also, "recipes" for various honey remedies (frequently combined with lemon and/or tea) abound.
The research is fairly limited regarding the effectiveness of treating a sore throat with these natural products. However, slippery elm is thought to possibly be effective.
Apple Cider Vinegar Gargle
A gargle with apple cider vinegar (with or without honey) has been recommended, but it is hard to imagine that vinegar (which is an acid) would be soothing.
Serrapeptase is a natural enzyme found in a number of products. In some studies, it has been shown to decrease throat pain, swallowing difficulty, and fever in people with a sore throat. In these studies, adults took 10 mg of serrapeptase three times a day.
