I used it for a couple of months as a part of the Buhner protocol for lyme disease. Hard to say which herb helps most but I'm making progress. Recently switched to Planetary Herbals andrographis - costs the same for 30 tablets more - but if you don't like bitter pills or plan to give this to your child I'd definitely stick with Now Foods as they're in a capsule form and easier to swallow, the taste is much more bearable as well. Buhner was right, andrographis is an exceptionally bitter herb.
