if you email me, i can put you in contact with the lady that i use, i have a mare that suffers from it too, Its a battle, especially this time of year with the increased chance of foot abesses. The oil i use is a natural anti imflamitory and pain killer, i did alot of reserch before trying it, but it was my last resort before going onto bute for long term use, The mare is in foal, so my decision was not taken lightly as a dead foal is no use, but unfortunately it will be the mares last year.
The farrier cant beleive the results i have had with it, and if he's happy im happy.
Costs about $40 for 375mls, but does last 6-8 weeks, I put it on twice a day for the first 2 weeks, and then down to once a day
