I'm always happy to hear from others that get relief from this demon disease and can't understand why more doctors don't recommend giving cilantro a try. I wrote up my results as well as the results of others and gave this write up to both of my dermatologists which seemed to have no interest in the heavy metal detox theory to aid in GD remission. Transcient Acantholytic Dermatitis, aka, Grover's Disease, GD, is normally transcient, it comes and goes and as you have learned, just like the rest of us, there are no prescription medications to cure this disease or that even offer relief. Yet doctors all prescribe them trying to give us hope.
My first outbreak was crippling and lasted one full year and subsequently it ran a 6 months on and 6 months off cycle for years. The subsequent break outs covered large areas, was terribly itchy and painful, but was not as severe as the first outbreak. We're all different in that regard. Mine was more severe then many, yet I read of one man on an Earth Clinic GD blog whose initial outbread lasted 6 years! He started on cilantro and he went into remission.
I'm writing what you probably already know, but want to to encourage you not to be discouraged if it returns. If that happens, return to the cilantro routine. For me drinking 1/2 bunch daily put my 1 month old break- out in remission, but it took months for a full recovery and up to one year for some of the dormant scabs to completely heal and fall off not to return. Now years later I have a hard time believing I had to live with such misery for so many years. But I'm not cured. If I start to get that tingle in my torso, always starts in my upper back torso, and feel the beginning of the tiny under the skin papuales start I go back on the blended cilantro for about a week and it resolves the sensation and what I believe are the beginnings of GD papuales forming on the inside disappear. Other then that my life is back to normal. Always be vigilant. Best of luck fellow suffer.

Severe years ago I had been diagnosed with Grover’s. After 2 months of symptoms I decided to try cilantro. I made a smoothie out of cilantro, yogurt and orange juice. Made in blender. In 5 days all symptoms disappeared. Just use plenty of raw cilantro from produce section of your grocery store.
