From Susan - Jan-15-2014
Cantharis is amazing for acute bladder infections. I love this product and it goes without saying, do not overdose, like anything too much has side effects. As for me, I have taken it for 5 days and not overdosing, following the naturopathic dr.'s instructions. I saw significant drop in the pain I had after the 1st dose I took (within the hour). I love it!!!
