I am so sorry you are dealing with sarcoids. My old grey TB had a bunch of them since I got him. Over the course of 4 years I had him we tried everything, but eventually lost him due to a sarcoid that grew internally into his spinal column (extremely rare, DO NOT worry about this happening to your mare).
He first came to us with multiple occult and fibroblastic sarcoids, the worst one being a grapefruit sized tumor on the side of his sheath, the smallest being dime sized occult lumps on his ears.
Here is what we tried, what worked and what made things worse. Note that during the whole thing he was able to stay in work and continue eventing, jumping and everything, just a few days off here and there.
Xterra: This worked exceptionally well for the first 8-9 months. It removed the largest protruding tumors. However, Hank became very weary of it and we eventually had to tie a hind leg up with one person holding it, and apply the xtera with a yard stick. And soon many smaller sarcoids were showing up in new locations.
De-Bulking with Liquid Nitrogen: The vet performed surgery on some large tumors that developed after using xtera. After cutting out the tumors, surrounding flesh was frozen with liquid nitrogen. This is when we discovered Hank is a heavy bleeder,and the surgery only made more sarcoids pop up in more areas.
Ditton Cream: Hank was much more willing to have this applied than the xtera. During treatment with the cream the sarcoids did not grow, but they did not really heal or shrink, either.
Wheat Grass spray: Using powdered wheatgrass made into a liquid spray. Saw no effect, good or bad. He liked to drink it for a treat, too.
OSU vet school: We started taking him to the vet school every 3 weeks. They started with a debulking surgery followed by cauterizing the areas. Then every 3 weeks he went in to get injections around the sarcoids of an inocculation developed from his own sarcoid cells to try and stimulate his immunoresponse. From the outside it seemed to work, though we now suspect is caused the sarcoids to morph into an internal infection form.
He handled everything like a champ, and through it all was otherwise comfortable and healthy, and a wonderful ride.
Best of luck, and hope that you can learn from some of my experiences. Remember to enjoy your horse! The sarcoids aren't likely to kill her!
