Amazing! That is all I can say! My child had Strep throat with a 103 fever today, I brought him to Dr. Singer after the medication was not working and his fever had dropped about 1/2 hour after we left his office. The amazing thing about this is the fact that Dr. Singer looked me in the eyes and said his fever would drop in a half hour. Dr. Singer truly is a holistic doctor and knows how to help people heal!
