I purchased Bartonella Plus. It's definitely doing something! However, my advice is go low and slow. I took too much at first (I increased by 1 drop a day and quickly got up to 10 drops per day) and then had a bad herx for several weeks. I cut back to 5 drops per day and am Ok here for now. I will eventually add more, but am going to do it very slowly over time. Slow and steady wins the race with this kind of thing!
