I love biocidin! It is a very powerful anti-microbial-a drop or two is all you need to start. It also deals with whatever is ailing you so no need to question what kind of bug is bugging you! I used it before and after recent oral surgery, and now using it to keep black mold from our home at bay in my body( besides moving from home til it’s remediated!). Our son took it with him while biking through Mexico down to Peru and used biocidin when he was feeling funky but no idea what was causing it. Works like a charm!!
