I had a rash/Hives that I believe came about as a result of eating berries that had been sprayed with pesticides, even though they came from a Farmers Market. Shortly after eating a bowl of these berries I broke out in a horrible rash all over my body. I have no food allergies and grew up eating berries, so I am only assuming they were tainted. Eleven days later and after taking Benadryl and a five day dose of dexamethasone, the rash/Hives continued to cover my body causing welts and severe itching. In fact my doctor told me to stop taking the dexamethasone because it seemed to be doing more harm than good. On my own I started taking two capsules a day of Life Extension Milk Thistle and within four days the rash finally went away. I can't say for certain that the milk thistle resulted in the rash finally going away, but it does make sense that once my liver was cleansed my skin cleared. I will continue to take one milk thistle a day on a daily basis to keep my liver free of toxins
