You know how stiff and sore you can feel after spending hours in the saddle. Your horse feels it too—especially after a tough trail ride, training session, or long haul.
You want your horse to feel and perform their best, bounce back quickly, and be ready for tomorrow’s ride. That’s where an equine poultice comes in! It’s a simple and natural barn staple for supporting healing and recovery.
We’ve tapped into Redmond’s own expertise with clay—as well as insights from a certified equine massage therapist and a former jockey—to answer your top poultice questions. Let’s break down the basics of what they do and when and how to use them.
A poultice is a smooth, spreadable paste made from natural clay and water. The clay does the heavy lifting, while water activates its healing properties. Some poultices include extra ingredients, like mineral salt or essential oils, to boost benefits.
Poultices are applied directly to a horse’s skin or packed into hooves to help relieve swelling and soreness. They’re also used to protect and draw infection from wounds or abscesses.
While poultices may be new to you or your horse, they’re actually an age-old remedy! People have used them for thousands of years to care for both themselves and their animals.
If you’re taking the time to poultice your horse, you want it to work. That means picking the right ingredients. Look for a natural product with a base of clay, like bentonite or kaolin. Bentonite, in particular, has powerful absorbing and adsorbing properties. (You can dive deeper into the science and benefits of bentonite clay for horses here.)
When hydrated, bentonite becomes a powerful cooling and drawing agent that helps:
Q. What does a poultice do for a horse? Poultices are versatile and helpful in many situations. Depending on the ingredients and your horse’s needs, a clay poultice can:
Always check your poultice ingredients and directions for use before applying. Essential oils might not be a good fit for wound care, and some deep wounds may require vet attention first.
Horses' legs are incredibly powerful—but they’re also quite delicate. With 20 bones, plus tendons and ligaments working under intense strain, legs are prone to stress and injury. Poulticing keeps legs healthy by:
Lindsay Robins, a certified equine massage therapist, recommends running your hands over your horse’s legs after a strenuous workout to catch early signs of stress or injury. Look for:
“If you find abnormalities, your horse will likely benefit from a poultice, Lindsay said. “It helps reduce swelling and inflammation in areas I can’t directly massage, like joints and ligaments.”
Former Utah jockey Jennifer Quarnberg agrees; she used Redmond clay poultices on her racehorses’ legs for 15 years.
“There was a noticeable difference in how quickly the muscles were ready to run again,” she said. “Tendons tightened quickly or stayed tight after a race, and overall, we just had better success keeping them sound. It worked on our racehorses, and it’s great for our family rodeo horses today.”
Yes! A bentonite clay poultice will relieve stocking up, which occurs when lymphatic fluid builds up in the lower legs.
“It usually happens after a horse is worked hard then put in a stall or trailer to stand,” Lyndsay said. “If your horse isn’t stretched out well enough or able to cool down long enough, their legs may swell and get sore.”
While not uncommon, stocking up shouldn't be ignored. It affects a horse’s performance and may lead to injury. Poulticing will help draw out that excess fluid and reduce swelling.
There’s no wrong time to poultice a horse—but there are situations when your horse will really benefit. Here are five Jennifer recommends:
Poultices are also beneficial on wounds—but check ingredients before applying. Cooling agents and some essential oils may not be appropriate for wounds. A simple clay poultice can help soothe and heal:

Most poultices work well with or without wraps—but wrapping can maximize results. Just make sure your poultice is safe to use under wraps before pulling out the polos.
Here are Jennifer’s preferred methods when poulticing her horses’ legs:
“Some people say using a brown paper bag is an old wives’ tale,” she said, “but it really helps draw out more swelling and heat. You can see a huge difference in the tendons if you wrap the poultice in a soaked brown paper bag.”
Poultice products vary, so check the instructions for use. But generally, these guidelines apply:
Poultices are a trusted essential every rider should have in their toolkit—and Redmond has your horse covered from head to hoof.
