I stopped using my smoothies at the end of November last year. I initially stopped ALL medication and "treatments" including the cilantro about two weeks prior to my visit to the Mayo Clinic on Dec 3rd. I wanted them to assess things without having anything in my system. As it turned out the Grover's papules and severe itching never came back and there was NO sign of grovers in the two biopsies I had done there. I do still have chronic hives and urticaria which came at exactly the same time my GD appeared. Super weird. But it is FAR less bothersome than the GD.
