I bought some magnetic wraps for my horse and used them when he was on box rest with laminitis but I couldn't say whether they helped his recovery or not. I figured that if they did improve the circulation then they were a good idea but who knows whether he would have had the same results without them? I think they're worth a try as at least you feel you've thrown everything at it!
