For mild thrush I have been using a 50/50 mixture of generic desitin diaper cream and generic lotrimin athletes foot cream. I put it in a small ziplock bag, mix well, cut off a corner and pipe it into a large syringe. To apply, use the syringe to get the cream into any cracks, then use a 1” chip brush to spread it on the surface of the frog. My last horse has pretty good feet but was susceptible to thrush at times. This mixture worked really well. It’s not something I came up with on my own, it was recommended by Pete Ramey

This article mentions copper sulfate, which is no longer recommend as it is too strong. He does a great job of explaining what happens when thrush turns painful and how the horse/hoof responds.
I think my new guy will eventually have good feet but it’s going to take a few more trim cycles. When I got him 6 weeks ago he had some pretty painful thrush and hadn’t been trimmed regularly until a few months before I got him. The thrush is almost gone and doesn’t seem to be painful anymore. It has been so dry here that I was looking for ways to increase moisture while maintaining antibacterial properties. That may no longer be a concern as it has started raining (yay) and hopefully that will provide the moisture he needs.
Last year the barn owner where I board asked me to dupe a hoof wax product. One of her horses has trouble if he gets too much moisture on his feet, his frogs get very soft and painful. Maybe this product would be helpful?
36% beeswax
36% coconut oil
22% raw honey
2% oregano eo
2% eucalyptus eo
2% lavender eo
This makes a really thick wax, take out a pea size piece, warm between your hands and apply to frog. It creates a moisture barrier that will stay on for several days.
