I m asking for a friend, she s 70 and has been battling a full body itchy rash for months. Her only relief is after a shower which she takes 3 a day. She said he hasn t changed soap etc. she is only drinking water all day - no vitamins either - for the past 2 days with a small dinner trying to detox her body. She did recently start taking zinc. Plus there was zinc I her multi but didn t see rash as a side effect.
