I am simply sharing my experience with this tea. Please keep in mind that all herbs/roots etc. may have side effects, and some may interfere with some medications. There are many books and internet sites for you to research the benefits as well as the side effects. Please research before trying anything. I have a disclaimer on my blog (I am not a doctor). I am sharing what worked for me. Marshmallow root has been used for years for sore throats. In the past, I have also made a tea with sage, peppermint, ginger, or mullein.
