The blackflies are small, biting insects that drive the horses crazy. If we don't do something about it, the horses end up with great scabby patches on all their tender areas. The ointment works like a charm to keep this from happening, if Charles puts a bit on them every day or two. The horses love it and let him work it into their ears and apply it on their chests, udders, etc.
He makes it from a secret blend of herbs infused in oil. Some of the herbs are insect repellants that work well enough to give the horses some relief. The others are healing herbs for any bites that they already have. The oil is soothing, too.
This year, for the first time, we might try selling some.
