Tried both ways, 3% straight and 3% mixed with an equal part of water, and they work! 3% straight works the best overall but tastes aweful. I got instant relief from the soreness, I began sneezing, my nose started to run, and I started coughing up the infection. I'm definitely putting this natural remedy onto my list of treatments!
