It was a horse I looked after and yes it really helped.
If you reasearch it you will see it makes sense in a lot of ways.
I think the main thing is you are treating it from the inside rather than putting lotions and potions on it which often seem to irritate it more.
We stopped all other treatment other than an occasional clean with just warm water and gave him the chestnut tincture and it gradually healed.
Of course I cannot say 100% it was the cure but I saw a difference if we ever ran out of it or it was missed from his feed.
Worth a try surely??
Good luck!
