I finally, after eliminating a million foods, realized that kombucha was making my excema worse. I used to only get it on my hands, and started getting a rash around my lips. I've read other stories of people's excema getting worse. It's just die-off though, and if you stick with it, it will get better. I wouldn't recommend drinking more than a couple of ounces a day to start, and slowly increase the amount.
