I’m a teacher and every once in a while I feel the early signs of infection…too early to take OTC medicine, but I know I have to do something before illness fully develops. For 2 days, the lymph nodes in my throat were tender to the touch and I was developing a sore throat, so I took a tablespoon of this tonic approximately every hour for a day, and I felt normal the next morning. Since then, I’ve been taking 1 tablespoon once a day as a continued preventative measure.
