My gelding was very itchy and flax seed did work wonders. If you decide to try flax seed, it is important to feed fresh or stabilized ground flax seed or most of the seeds will be pooped out whole and won’t do any good! Ground flax seed is very unstable so that won’t help either, unless freshly ground. I use a stabilized ground flax seed product made by HorseTech (Glänzen, or in my case, Glänzen Lite) that really helped him. I am not guaranteeing that flax seed will cure your horse, but if you decide to use flax seed, make sure you use a product that will work.
