Is it possible that I am allergic to natural herbal medicine(s)? I have been under acupunture treatments for anxiety+depression and tinnitus since May, 2012. During this time, I've been taking various herbal pills for tinnitus, anxiety+depression and insomnia. The first ones are Er Long Zuo Ci Wan (for one week) for tinnitus along with An Mian Tang (for a month) for sleeping aids/insomnia, Shu Gan Wan (for one week), Liu Wei Di Huang Wan (for a month), and recently my acupuncturist switched An Mian Tang with Tian Wang Bu Xin Dan because I had dizziness and headaches with An Mian Tang.
I think some time when I was taking Liu Wei Di Huang Wan, I noticed that all my ten finger tips started turning pink/red, my left thumb and index seemed very sensitive to touch (the same feeling like I have a light burn). I asked my accupuntist but he was unclear. He gave me a couple points on the thumb and index tips which were pretty strong but it didn't help much. Is it possible that one of the herbal medicine caused allergy or I am overtreated/mistreated? I don't have any food allergy that I've known of and my diet is normal. When I've recently stopped taking the herbal pills all together and I can still see the finger tips are still slightly pink.
