What plant soothes sore throats?

Aloe Vera

The gel from the inside of an aloe vera leaf is a natural emollient that can soothe sore throats. It can also help to reduce inflammation and pain. To use aloe vera for a sore throat, mix 1 tablespoon of aloe vera gel with 1 cup of warm water. Gargle with the mixture for 30 seconds, then swallow it. You can repeat this process every few hours as needed.
