Yes, dry salt aerosol therapy is a real, drug-free treatment for respiratory and skin conditions in horses, and the technology is now protected by patents and used across multiple species. This article examines the myths and facts around equine salt therapy, with the horse as the original proving ground for a platform now licensed for poultry, swine and companion animals.

What is equine salt therapy and how does it actually work?
Equine salt therapy is the inhalation of micronised pharmaceutical-grade sodium chloride delivered as a dry aerosol, combined with topical contact with the same aerosol for skin conditions. A halo-generator micronises the salt into particles small enough to reach the lower airways, bronchi, bronchioles and alveoli, according to Equine Salt Therapy’s history and invention page.
The inhaled particles stimulate the mucociliary escalator, the natural clearance system that moves mucus and trapped debris out of the airways. This is the same mechanism that keeps healthy lungs clear, but the dry salt aerosol gives it a measurable boost.
The practical format is straightforward. A treatment takes fifteen minutes and is recommended over three consecutive days. There is no sedation, no injection and no forced administration. The horse simply stands in the treatment space while the aerosol does the work. The Horse reported that micron-sized salt particles penetrate deep into the lungs to reduce inflammation, dissolve bacteria and cleanse the respiratory system.
Kane Harris noted that the treatment effectively cleans dirt and grime out of the horse’s lungs and clears mucus from the airways in an equine salt therapy overview.
Where did equine salt therapy come from and who invented it?
Equine Salt Therapy was invented and founded by Richard Butterworth and built in Australia. The invention is protected by patents covering the “Livestock Treatment Method and Apparatus,” the delivery system, the halo-generator and the Ultisalt™ formulation, according to the history and invention page.
Ultisalt™ formulations were developed over 12 years of research and development. That timeline reflects the complexity of creating a salt formulation that behaves predictably in real-world equine environments, not just in a laboratory.
The horse came first for a reason. An equine athlete moving at speed places extreme demands on its respiratory system, and that made the horse the natural proving ground for a treatment designed to support airway clearance and skin health. Once the system proved itself in equine applications, the platform extended to other species.
The patent protection is significant because it covers the method and apparatus as a complete system. That means the delivery technology, the halo-generator and the salt formulation are all part of one protected platform.
What is Ultisalt™ and why does the salt formulation matter?
Ultisalt™ is a proprietary salt formulation developed specifically for equine physiology, not standard pharmaceutical-grade salt. The distinction matters because standard pharmaceutical grade salt clumps in humid settings, which would make consistent aerosol delivery unreliable in many climates, according to the history and invention page.
The air filled porosity of Ultisalt™ is tailored to cope with different uses and climates. That engineering detail means the salt flows and micronises consistently whether the treatment space is in a dry inland stable or a humid coastal training centre.
Certain modalities include Thyme Oil to loosen mucus. The addition is a targeted formulation choice, not a fragrance decision.
The Enduro Formula includes alkalising agents that have alleviated TCO2 levels to a safe performance buffer without breaching thresholds. That formulation work is part of the 12 years of research and development behind Ultisalt™.
What conditions can equine salt therapy help with?
Equine salt therapy supports respiratory conditions including equine asthma, heaves, Recurrent Airway Obstruction (RAO), lower airway disease and travel sickness. The Horse reported that dry salt therapy is a natural, drug-free therapy that helps combat these respiratory issues.
Skin conditions treated by topical contact with the aerosol include mud fever, rain rot, dermatitis, boils and ringworm. The same session that delivers respiratory support also exposes the skin to the dry salt aerosol.
The dual-action premise is central to the treatment. Respiratory and skin conditions are treated at the same time in one fifteen-minute session, which is a practical advantage for busy stables.
DVM360 reported benefits including decreased travel sickness, lower veterinary bills and quicker race times in a Kane Harris also noted the treatment clears dirt and grime from the lungs in an equine salt therapy overview.
Is equine salt therapy legal and compliant in racing and competition?
Yes, dry salt therapy is completely compliant with competition rules and regulations in racing and every equine performance discipline. DVM360 confirmed this compliance.
The reason is simple. The treatment is 100 percent drug-free, so there is no withdrawal period and no pharmaceutical footprint. A horse can receive a session and compete without any regulatory concern.
Equine Salt Therapy describes the system as reducing reliance on medically important antibiotics and the pharmaceutical footprint of training centres, according to the history and invention page. That positions the therapy as a stewardship tool, not just a performance aid.
The compliance profile matters for trainers and owners who operate under strict anti-doping rules. A drug-free treatment removes an entire category of risk.
What does the science and real-world race results say?
A UK study on racehorses found that a proportion of horses flagged as underperforming were suffering from undiagnosed Lower Airway Disease, according to the history and invention page. That finding matters because it suggests some performance problems have a treatable respiratory cause.
Respiratory disease is the second most common cause of lost training days in horses, behind only musculoskeletal injury. The scale of that impact makes respiratory support a practical priority for trainers.
The Santa Anita Park result provides real-world race evidence. Gregorian Chant, Strike Me Down and Thanks Mr. Edison, all undergoing equine salt therapy, finished first, second and third in the $70,000 Clockers’ Corner Stakes on January 31, as reported by The Horse.
How did a horse therapy become a patented multi-species platform?
The global equine industry is valued at approximately $300 billion annually, according to the history and invention page. That scale explains why the equine application came first and why it attracted the research investment behind the patented system.
Equine Salt Therapy offers Licensed Business Opportunities and Master Licenses for Equine, Poultry, Swine and Companion Animals. Territories are sold under License and Master Licenses are available for various modalities under US Patent 11,497,593 and CA 3019046, with pricing from $110,000 to $1,000,000.
Licensees are referred to as Practitioners and animal clients as Salties. The terminology reflects a structured business model built around the patented platform.
The extension from horses to poultry, swine and companion animals follows the same physiological logic. Any animal with a respiratory system and skin can benefit from the same dry salt aerosol mechanism.
What are the most common myths about equine salt therapy?
Myth: it is the same as a human spa salt room. The reality is a patented delivery system with a proprietary formulation, not ambient salt. The halo-generator and Ultisalt™ formulation are engineered for equine physiology, according to the history and invention page.
Myth: it is unproven or alternative. The reality is patent protection and documented race results. The Santa Anita Park trifecta and the UK study on undiagnosed Lower Airway Disease provide real-world evidence, as reported by The Horse.
Myth: it requires medication or sedation. The reality is a drug-free, non-invasive treatment that is competition compliant. DVM360 confirmed compliance with racing rules.
Myth: it only works for horses. The reality is the platform now extends to poultry, swine and companion animals under the same patent protection.
