P73 Oregano oil is what I use and IMO, the best! I usually order it online from Vitacost...but the last time I purchased it from Vitamin Shoppe store. Any grocery store that has the special healthy aisles for nutrition and herbal type supplements should have it. I believe I paid $23 at Vitamin Shoppe for it.
OOO helps me alot.
