I assume you've tried blending fresh or fresh frozen cilantro. That worked for me and haven't had any major issues in 5 years. I get a few papuales and start on the cilantro again for a few days. Have you had the 5 Day Extended Patch Test for Allergic Contact Dermatitis, ACD, an allergic form of eczema. Like you I have both ACD and GD.
Thanks for the tip on State of Cotton. I have a few good sources too.
Have you shopped at Cottonique? Among my ACD allergies I am allergic to all blended materials. So elastics are out for me. On this site you can find quality soft cotton for underwear. Of course temper your expectations. Bras must be seamed and have drawstrings or adjustable straps. However these bras would not be suitable if you are large breasted. Same with panties. They have heavy duty quality cotton socks that work well, not pretty. Buster Brown makes a nice, cute 100 cotton lightweight sock, but they wear out quickly. LifeKind, a pricey source for bedding and linens has my favorite 100 cotton blanket, wonderful for summers. Super high quality. Ridiculously priced, but white sale times they also mark down their quality products and I add to my collection. These cottons simply don't wear out. The White Cotton Gown makes my favorite night gowns. Very soft, I wear all seasons. If it's colder out I wear an 100 cotton t-shirt, long sleeve or short sleeve, under them and I like to order a size up for that reason. Good value overall and they last forever.
Grover's never responded to any topicals, px or otc for me either. Steroids topical or injected did nothing. A complete waste of money, but at least they gave me temporary hope.
I'm writing this free of all forms of eczema which I had for years, so keep educating yourself and don't limit yourself to one dermatologist or allergist.
