Have you considered trying fresh cilantro instead of the capsules? The reason I ask is that fresh cilantro was a miracle for me. I started it and within 3 weeks could tell it was helping. After 2 months I was 90% better. Over the holidays I took a 10 day trip and I switched to capsules and by the end of my trip, my itch was popping back out. I know that cilantro doesnt work for everyone so I don’t mean to harp on about it. We are all on our own journeys. Just wanted to share that for me—fresh worked and capsules didn’t. Wishing you all the best as you search for relief!
