What a clay poultice for horses is
A clay poultice (“cretata” in Italian stable jargon) is a clay-based wrap spread over the horse's legs after work. It is one of the oldest gestures in equestrian tradition: grooms and riders have used it for generations to relieve tendons and ligaments at the end of training or competition.
The principle is simple: as the moist clay dries slowly in contact with the skin, it exerts an osmotic, cooling action that helps drain excess fluids and release the heat accumulated in the tissues during effort. Modern poultices combine this mineral base with targeted botanical extracts, such as arnica.
What it is for: the benefits on tendons and legs
The poultice is applied above all to cannons, fetlocks and flexor tendons — the structures most stressed by work — and is indicated for:
- Relieving tendons and ligaments after training or competition
- Reducing swelling and heat in the legs after effort
- Draining fluids accumulated in the tissues (osmotic action)
- Cooling the legs during periods of intense work or hot weather
- Remineralising the skin thanks to the minerals in the clay
When to use it
- After every demanding session: jumping, dressage, racing, endurance
- After competition, as part of the recovery protocol
- After long journeys, when the legs stand still and tend to swell
- During periods of intense load, even in cycles of several consecutive days
- In summer heat, for the prolonged cooling effect
Clay, poultice or wrap: clearing up the terms
The terms overlap and are used interchangeably around the stables: clay is the raw material; the poultice is the ready wrap — clay already mixed, often enriched with botanical extracts — and by extension the gesture of applying it. If you search for “clay for horses” or “clay wrap”, you are talking about the same thing.
Not all clays are the same
The quality of a poultice depends first of all on the clay it is made of: mineral composition, grain size and absorption capacity vary greatly from deposit to deposit. Miraclay poultices are born from Nocera Umbra clay, an Umbrian lacustrine clay known since antiquity, with 11 naturally occurring active minerals — silicon, magnesium, calcium, iron and potassium among others.
Clay is not simple “mud”: it is the active ingredient of the poultice. Choosing it well means choosing what actually reaches the horse's legs.
Ready to use or powder to mix?
Powdered clay must be mixed with water at every use: economical, but consistency and performance change with every preparation. A ready-to-use poultice has a constant formulation — density, moisture and active ingredients always the same — spreads in a few minutes and requires no equipment. For those who work their horse every day, the difference in time and regularity is tangible.
Which poultice to choose: routine or intensive recovery
The right choice depends on the intensity of the work. For the daily routine — relief after training, leg maintenance — the answer is a mineral poultice like ArgiStrong, designed for the well-being of muscles, tendons and ligaments day after day.
For intensive recovery — after competition, with marked swelling, during periods of maximum load — something more is needed: ClayPower combines the same Nocera Umbra clay with 99% fat-soluble arnica, which penetrates deeply and enhances the decongestant action of the wrap.
Both are ready to use, non-doping and compatible with FEI and FISE protocols — they can be used on competition days without worries.
How to apply it, in short
- Clean and dry the limb before application
- Spread a 1–2 cm layer from top to bottom, covering cannon and fetlock
- Let it work for a few hours or overnight, with or without a bandage
- Remove with lukewarm water in the morning

Frequently asked questions about the clay poultice
- How often can the poultice be applied?
- Even every day during working periods: it is a natural wrap for external use. In the routine it is applied after the most demanding sessions; after competition it can continue for several consecutive days.
- Is a bandage necessary?
- It is not mandatory: the poultice also works in the open air, drying slowly. A bandage prolongs the moisture and the action time — useful for overnight intensive recovery.
- How long should it stay on?
- From a couple of hours up to a whole night (6–8 hours) for maximum effect. It is removed with lukewarm water, without deep rubbing.
- Is the poultice a doping agent?
- Miraclay poultices are non-doping and compatible with the FEI and FISE anti-doping protocols: they can also be used on competition days.
- Is it suitable for summer too?
- Yes, it is one of the best moments: the cooling effect of the clay helps the legs release the heat accumulated with work and high temperatures.
In short: the clay poultice is the most natural, time-tested way to take care of the sport horse's legs. With a quality clay and the right formula for your workload — ArgiStrong for the routine, ClayPower with arnica for intensive recovery — a few minutes at the end of the day become an investment in the health of tendons and ligaments.
