I was diagnosed with systemic candida last year and have been on the anti-candida diet along with various treatments for almost 9 months now. My die-off has been quite severe, so initially I couldn't tolerate some treatments without feeling a lot worse. I have been using Canherb now for almost 2 weeks, and must say that this (along with Threelac) seems to be the best treatment I've tried. I am starting to feel so much better.
