Marshmallow Root has been used for several years to treat a sore throat. Its high mucilaginous content may make it a useful remedy for treating coughs and colds.
This remedy is not recommended for pregnant women or people who have diabetes. You can add one tablespoon of dried marshmallow root to a cup of boiling water and steep it for about half an hour.
Then, strain the solution, if you want to add some honey and drink it.
