Instead of a poultice, which is a clay compound, I would consider carrying a small plastic bottle of liquid --- unless you want to carry the vet wrap and a pair of scissors with you to do a wrap???
I use both the liquid and the clay poultice "Sore-No-More". It is all natural and its primary ingredient is arnica. It's a cooling clay and works very well on my horse.
I have arthritis in my hands and will coat my hands, then vet wrap them before I trim my horses. Ack -
the links come up as "search results"; I guess that's because I went to Valley Vet's website and did a search on their site. I buy from Valley Vet as they are great to do business with and offer discounts for buying some things in bulk. Search Results -
It really is a "cooling clay" as advertised.
I hate Absorbine's clay poultice as it feels gritty, takes a lot of Dawn dish soap to get that stuff washed off and makes my horse's legs itch.
Numotizine is a sweat and really works but that stuff makes my mouth tingle and feel funny - even when I use rubber gloves. It's reacts against me the same way the old ammonia blueprints did, back when I had a real job. The blueprint room had to have my stuff ready & waiting outside the door; I was so sensitive to the ammonia, I couldn't even go inside the BP room.
Numotizine does the same thing
Or, there's the AnimalIntex poultice pads which are also all natural. I love those and they work but they work best if they're wet. Then you're back into haveing to vet wrap them onto the horse and having either warm or cold water to soak them in before applying them Search Results -
They're not cheap either
