A New Paradigm

Laminitis is a Mast Cell Activation Syndrome

"The inflammatory mediators elevated in laminitis are produced and distributed by mast cells — the same as in other systemic inflammatory disorders."

Laminitis is a painful and debilitating inflammatory response expressed in the feet of horses. The traditional view treated it as a foot condition — but research reveals it is a systemic immune disorder driven by mast cell dysregulation.

Mast cells are multi-functional immune cells found in all vascularized tissue. When over-activated by local and systemic stress, mast cells release inflammatory mediators that degrade connective tissue in the feet, leading to the pain and damage of laminitis.

Studies of horses with laminitis find two-fold increases in mast cell number and activation compared to healthy horses, along with elevated cytokines and inflammatory mediators — confirming the mast cell activation model.

🔬

Multiple Organs

GI tract, feet (digits), eyes, and skin are all affected — confirming systemic mast cell involvement.

🧬

Elevated Mediators

Studies find higher mast cell density and elevated inflammatory mediators in lamellar tissue of horses with laminitis.

🩺

Immune Dysregulation

Mast cells regulate vascularity, wound healing, homeostasis, and defense against infection. Over-activation disrupts all of these.

💊

Targeted Treatment

By blocking aberrant mast cell activation, Laminil halts the inflammatory cascade and restores vital function.

Laminitis is preventable and treatable

When administered prophylactically, Laminil stabilizes the immune system and prevents inflammatory episodes. When administered in the acute phase, it modulates the response and opens a window of opportunity for the horse to heal and recover.

Topical Application

Laminil™ Cream

120 gram per jar — Transdermal base

Laminil Cream applied to the coronary band, heel bulbs, and frog puts Laminil into circulation throughout the foot. It stabilizes mast cells in connective tissue, restores vascular function, improves blood flow, and promotes healthy hoof growth.

Laminil Cream promotes hoof growth by halting mast cell activation, opening growth receptors, and enabling healthy hoof development. Hoof growth typically increases by 30% in 60 days.

One jar is sufficient to treat two feet for 30 days
Compatible with all known drugs and treatments, including NSAIDs and steroids
Treats swollen joints, strained ligaments/tendons, and dermatitis
Available by veterinary prescription
Sterile Solution

Laminil™ Solution

60mL / 10% cromolyn sodium per vial

Laminil Solution is designed for intra-muscular (IM), intravenous (IV), and intra-articular (IA) injection. One vial is sufficient for two limb perfusions or one IM loading series.

The IM Loading Series of 12 injections in 30 days stabilizes mast cells, mitigates inflammation, resets the immune system, restores vital functions, and addresses underlying systemic inflammatory conditions.

IM Loading Series — 12 injections in 30 days to stabilize the immune system
IM Cluster — 5 injections in 7 days to prevent anticipated episodes
IV Limb Perfusion — acute treatment by veterinary injection
Joint Injection — added to corticosteroid injections to prevent inflammatory response
Active Ingredient

The Gold Standard: Cromolyn Sodium

The active pharmaceutical ingredient in Laminil, cromolyn sodium, is an FDA-approved mast cell stabilizing drug used for treatment of allergies, asthma, and other mast cell disorders in humans — repurposed with precision for equine care.

Cromolyn is considered the "gold standard" for mast cell stabilizers and is used in scientific experiments worldwide to identify the role of mast cells in various inflammatory diseases.

01
Not metabolized or absorbed in the body — excreted intact with a short 90-minute biological half-life and virtually non-detectable after 24 hours.
02
Non-toxic at 80× the maximum dose, does not bio-accumulate, and can be used perpetually without harmful side effects.
03
Does not interact with any known drugs or herbal treatments. Compatible with NSAIDs, steroids, and other pain medications.
Patent Protected

The use of mast cell stabilizers to prevent and treat laminitis is protected by international patent.

The herbal origin of cromolyn traces to ancient Egypt — Dr. Roger Altounyan discovered it in 1965 after studying Ammi visnaga (khella), a muscle relaxant used since ancient times. His discovery launched an entirely new class of compounds.

Treatment Guide

Treatment for Every Phase

Laminil can be used prophylactically and therapeutically across all stages of laminitis. Select a condition below to see the appropriate treatment approach.

Objective

Stabilize the Immune System — Prevent Acute Episodes

Horses with developmental laminitis have over twice the number and activity of mast cells as healthy horses. Pre-treatment with Laminil Cream and IM injections prevents aberrant mast cell activation and acute inflammatory episodes.

Mast cells play central roles in insulin dysregulation, obesity, GI tract disorders, and metabolic syndrome — all conditions that set the stage for laminitis. Early intervention is the most effective strategy.

Recommended Treatment
Laminil™ Cream — applied daily
Laminil™ IM Loading Series — 12 injections over 30 days
Prevention is more effective than acute treatment
Objective

Prevent Another Laminitis Episode

Laminitis episodes can be prevented when expected. Treatment should begin before acute symptoms appear and before triggering events such as severe weather, a long trailer ride, or hard work on hard ground.

In some cases, Laminil Cream alone prevents an episode. In others, the IM Cluster is effective. Combined, they offer the most robust protection for chronically vulnerable horses.

Recommended Treatment
Laminil™ Cream — daily
Laminil™ IM Cluster — 3–5 injections in 5–7 days before anticipated episode
Preventing an episode is easier than treating acute laminitis
Objective

Relieve Acute Symptoms Immediately

In a limb perfusion, a tourniquet is fastened above the knee or fetlock and Laminil Solution is injected into the vein below. Laminil perfuses the lamellar connective tissue, blocks mast cell activation, and stops the inflammatory cascade at the source.

The symptoms of acute laminitis — heat in the feet and pounding digital pulse — subside in the first hour after Laminil perfusions. Immediate icing (cryotherapy) while preparing for treatment is also recommended.

Recommended Treatment
Immediate cryotherapy — ice all four feet in icy water for 40 minutes
Laminil™ IV Limb Perfusion — all four feet, as soon as possible
Laminil™ Cream daily
Laminil™ IM Loading Series beginning 24 hours after first perfusion
Objective

Prevent Inflammatory Response to Corticosteroid Injections

Mast cells are abundant in the synovial lining. Aberrant activation of synovial mast cells produces MMP-9, IL-6, and other mediators that degrade the synovial membrane. Laminil stabilizes these mast cells and prevents the inflammatory response to routine procedures.

Fifty milligrams of Laminil added to a corticosteroid injection can prevent an unlikely but tragic inflammatory response to a routine joint procedure.

Recommended Treatment
50mg Laminil™ Solution added to the corticosteroid injection solution
Laminil™ Cream applied transdermally to the joint area
Objective

Prevent Inflammation from Injury, Transport, and Environmental Stress

Stress of air and ground transport and quarantine can induce laminitis in perfectly fit horses. Hard work on hard ground, severe weather, farrier visits, and injury all present inflammatory risk. Proactive Laminil treatment prevents these episodes.

For supporting-limb or surgery-related laminitis, IM injections begin as soon as possible after the initiating injury and continue through surgery and recovery.

Common Triggers & Response
After the farrier — apply Cream to prevent inflammatory response
Trailering — apply Cream before and after transport
Hard work — Cream and IM before/after training and competition
Surgery — add Laminil to IV drip in hospital to prevent supporting limb laminitis
Severe weather — treat vulnerable horses before cold front arrives
