Global herbs Fly free

[FAYEFUDGE]

Has anyone tried this?
Just wondered if it was any good?
My boy was tortured last year and I’m willing to try anything this summer!!

Scanning the ingredients it contains at least 2-3 species containing compounds which are toxic to herbivores if given in large amounts. You won't be feeding enough to do harm but
I would not feed it.

I think most things on the market that you feed to deter flies basically rely on plants that produce compounds to deter herbivores and so the horse 'tastes' or smells like them a bit to the flies. But they are anti herbivore compounds. So.
Like garlic is massively anti microbial and the horse's gut biome is so sensitive that I'm not sure I would feed anything with potential to disrupt that

We have found black salt to be effective with a sweet itch horse.
It stinks but he doesn't mind.
