I am truly thankful to have had your PDB Echinacea and Goldernseal on hand when I developed an extreemly sore and burning throat along with chronic sinus congestion. I was so sick it reminded me of the days before I had my tonsils removed. I took the recommended daily dose and immediately noticed improvement especially with my throat pain. At night, I kept the bottle next to my bed and when I woke up with my throat pain I took a drop or two and would go back to sleep . After four days, my sinus congestion improved greatly along with my sore throat going away. My ears were paining as well, I used a baked onion poultice for them. So thanks to our Creators herbs, for your tincture expertise and my onion friend - I'm able to get back to my feel better life.
