If it doesn’t say caffeine free, then it very likely has caffeine. I drank green tea everyday and coffee once a week throughout the diet; this is my only cheat item other than salad dressing. If you keep the bad stuff to the minimum, your body should do OK getting over candida. However, like Able said, any caffeine sets you back and is hard on the system when you are getting over a heavy health problem.
Green tea has great anti-inflammatory and anti-oxident properties (plus many more).
