Laminitis in horses: treatment and support.

Laminitis is not just sore feet. It is a breakdown of the laminar tissue that bonds the coffin bone to the hoof wall, and once that tissue is damaged, the bone itself can begin to rotate or sink. That distinction matters more than most owners realise, because it changes the urgency of what comes next.

Step 1: Call your vet and get an x-ray

Before anything else, call your vet. A clinical examination alone cannot tell you whether the coffin bone has moved. An x-ray can. That image shapes every subsequent decision, from how the farrier approaches the trim to how much movement is safe.

For horses over 12, ask for a blood test for PPID (equine Cushing's disease) at the same time. PPID disrupts cortisol metabolism and creates chronic insulin dysregulation, which is one of the most common drivers of recurring laminitis. If your horse has been through this before and you have never checked for PPID, this is the moment to do it.

Step 2: Get the horse off hard ground

Soft footing reduces concussive loading on inflamed laminae. Wet sand, sawdust, or wood shavings all work. Avoid dry sand. Horses eating from the ground can ingest enough to cause sand colic, which is a separate problem you do not want alongside laminitis.

Hoof boots are worth having. They add cushioning and make movement less painful during the acute phase, which helps the horse rest properly rather than standing rigid and loaded on one leg.

Step 3: Ice the hooves

Continuous cryotherapy applied to the feet in the first 72 hours of an acute episode is one of the most evidence-supported interventions in laminitis care. Cold slows the inflammatory cascade in the laminar tissue and limits secondary damage. The practical approach is a bucket of iced water or purpose-built ice boots kept on throughout the acute phase. This is not a one-hour treatment. Research supports continuous cooling for as long as the acute phase lasts.

Step 4: Overhaul the diet immediately

Remove the horse from grass. Pasture, especially in spring and autumn when fructan levels peak, is one of the primary dietary triggers for insulin-driven laminitis. No grain either. The goal is to drop dietary non-structural carbohydrates (NSC) as low as possible while maintaining gut function.

Keep feeding hay. A horse with laminitis still needs forage. Soaking hay for 30 to 60 minutes leaches water-soluble sugars and can meaningfully reduce NSC content [1]. For horses that eat fast and push the hay around, a slow-feeder hay net limits intake without forcing the gut empty. An empty gut raises cortisol, which is exactly what you do not want.

Step 5: Targeted herbal and mineral support

Most laminitis cases have a metabolic component. The herbs and minerals below address the mechanisms most commonly implicated: insulin response, circulation, liver function, and hoof tissue integrity.

Insulin response and metabolism

Magnesium deficiency impairs insulin receptor sensitivity [2]. Horses on laminitis-prone pastures are frequently low in magnesium, partly because high-fructan grass grows fast in soils where mineral availability is uneven. Supplementing magnesium is low-risk and addresses a real metabolic gap in most of these horses.

Berberis vulgaris (barberry) has been studied for its effect on fat and glucose metabolism. Berberine, its main active alkaloid, works through a mechanism comparable to metformin in metabolic syndrome models [3]. It is not a replacement for veterinary treatment in PPID, but it is a useful metabolic support herb in the broader protocol.

Circulation and hoof perfusion

Damaged laminae have poor blood flow. Pinus pinaster (maritime pine bark) and L-arginine both support vascular dilation. L-arginine is a nitric oxide precursor and has documented blood-pressure-lowering effects through vascular mechanisms [4]. Getting blood into the hoof is part of how the laminar tissue repairs.

Hoof tissue integrity

Equisetum (horsetail) is the primary botanical source of bioavailable silicon. Silicon is a structural component of connective tissue and hoof wall, and research supports its role in tissue integrity and repair [5]. MSM (methylsulfonylmethane) provides organic sulfur, another structural element in keratin and hoof tissue.

Liver and cortisol support

Chrysanthellum americanum has documented hepatoprotective activity in animal models [6], and Silybum marianum (milk thistle) has its own well-studied liver-protective mechanisms [7]. Liquorice has a known role in cortisol metabolism: its compounds inhibit the enzyme that normally breaks cortisol down, which prolongs its activity in the body [8]. In horses with PPID who are not yet medicated, liver and cortisol support can provide some palliation while the full diagnostic picture is established.

Blood oxygenation

Chlorella is a high-magnesium microalgae. The chlorophyll molecule is structurally similar to the heme group in haemoglobin, differing primarily in its central magnesium atom rather than iron [9]. In practice, it is used to support red blood cell quality and oxygen transport to peripheral tissues, including the hoof.

Step 6: Hoof care and farrier work

The farrier's role in laminitis is not just cosmetic. Correct trimming and, in rotation cases, remedial shoeing directly influence whether the coffin bone continues to migrate. The trim should relieve rotational forces by lowering the heel and breaking the hoof-pastern axis appropriately for that x-ray, not for a generic template.

Step 7: Movement (but not during the acute phase)

This is where well-meaning owners cause damage. Movement during the acute phase, when the laminae are actively inflamed and the coffin bone is at risk of rotation, increases mechanical stress on already-compromised tissue. Rest the horse completely until the vet confirms inflammation is controlled and the x-ray is stable.

Once the acute phase has passed, gentle movement on soft ground is beneficial. If the horse moves around voluntarily, that is a good sign and worth encouraging. If he is reluctant, do not push it. Forcing movement on a horse that is still uncomfortable will set recovery back rather than advance it. The pace of return depends on the severity of the original episode and what the follow-up x-ray shows.
