Not exactly Liver Flush as in Hulda but I've used some Essiac tea I prepared last night. After 3.5 hours I've started to feel extremely cold my arms are covered with goosebumps. The temperature according to others is fine and I was fine until now. It was quite a warm day! Is this a reaction to cleansing the liver? I think I might have read about this with Liver Cleanse programs which Essiac is doing.
