Erms, well I haven't tried it yet, but I know that lavender oil is an antihistamine (something that combats/suppresses allergic reactions). My totally cool teacher told me about it when I had some sort of weird thing goin' on with my elbow, and had some that he let me use. It got 99% better within 10 minutes! It was a mix between lavender oil and grapeseed oil, and worked wonders on me.
I know that the pH of a horse's skin is different from humans, but the next time that Lunar or another horse breaks out in random hives, I think I'll try it! (If anyone has anything to say about this idea, please please let me know, because I don't want to accidentally do something bad to my horses while I'm trying to help!!)
The mix was mostly lavender oil with about 1/8 grapeseed oil, I believe(:
