I have had Grover’s disease for almost 2 years, diagnosed with two punch biopsies. I tried everything standard and many other experimental treatments like ipl laser, chemical peel, dapsone gel, going off sugar and diary and an at home blue light therapy. The only things that temporarily got rid of the red bumps were the ipl and topical steroid. After a year of the steroid cream my skin started to thin and turn lobster red and the rash was spreading up onto my face. I decided to quit the steroid for good and was desperate for another option. I had read that some people had great success with cilantro smoothies but had dismissed it as anecdotal. BIG MISTAKE! It works!!! I have been doing a smoothie every day for two weeks and only have one spot left. On week two I added Chlorella tablets too and that accelerated the improvement more rapidly. The itching and ruddy color is gone. Each day is a little better. Thank goodness I took a before and after picture. I had to share for all those other people out there who haven’t tried cilantro. I hope this helps others.
