Essential Oils and FEI Horse Competition Rules
Learn how FEI competition rules treat essential oils for horses, what riders must know before using them, and why checking with your vet and federation matters.

You are at the stables the week before a show, and someone mentions they use an essential oil rub on their horse's legs after a workout. If you are reading this, you are probably wondering whether that is allowed under FEI rules. The straight answer is that the FEI maintains a list of prohibited substances, and many naturally derived substances, including compounds found in essential oils, can appear on it. Before using any essential oil on a horse that competes, you must check the current FEI prohibited-substances list and speak with your veterinarian and your national federation.
Essential oils are not automatically permitted just because they come from plants. The same purity and sourcing standards that make doTERRA oils appealing for your own routines do not change what the FEI considers acceptable for a competing horse. For riders, the responsible approach is cautious, informed, and always documented.
Why FEI Rules Matter for Essential Oils
The FEI exists to keep equestrian sport fair and to protect horse welfare. Its anti-doping and controlled medication rules apply to competitions worldwide, and they cover substances that could affect performance or mask injury. A plant extract that seems gentle to you can contain compounds the FEI classifies differently.
This is where we see the difference between essential oils for humans and essential oils for horses. When we enjoy Lavender in a diffuser at home or use Deep Blue for our own post-ride massage, we are making choices for ourselves. A horse cannot read the label, and the FEI does not grade oils by brand but by what they contain.
| Consideration | For You | For a Competing Horse |
|---|---|---|
| What matters | Your personal preference and how you feel | What the FEI prohibited-substances list says |
| Who decides | You | Your veterinarian and your national federation |
| Documentation | Not needed | Essential, including any product used in the days before competing |
| Risk of rule violation | None | Real, even with natural products |
The FEI's rules also include detection times for certain substances. We will not guess at those here, because numbers can change and a wrong number could cost a rider a clean result. The only safe path is to look at the current list yourself and ask the experts who oversee your horse's care.
What to Do Before Using Any Oil on a Competition Horse
We have learned that horse people are practical, so here is the process we suggest, step by step.
- Look up the current FEI prohibited-substances list and read the categories carefully.
- Bring the exact product, with its full ingredient label, to your veterinarian.
- Ask your vet whether anything in that product could fall under FEI rules, even indirectly.
- Confirm with your national equestrian federation before you use it during a competition window.
- Keep a written record of what you use, when, and how, in case a stewards enquiry comes up.
This list matters more than any single product recommendation. Whether you are drawn to Frankincense for your own focus or Copaiba for your routine, the horse's competition status changes everything. Some riders enjoy Roman Chamomile in their own space, but that is a human choice, not an equine protocol.

If you are still asking whether any use is sensible at all, read Are Essential Oils Safe Around Horses for the cautious, vet-first perspective.
We also appreciate doTERRA's commitment to CPTG testing and purity. That quality standard matters for your own use of oils like Vetiver or Cedarwood. What CPTG does not do is override FEI rules, and no oil should ever take the place of veterinary advice for an animal.
Frequently Asked Questions
Are essential oils banned completely by the FEI?
Not as a blanket category. The FEI bans specific substances, and some compounds found in plant extracts may be on that list. You must check the current list and consult your vet rather than assume an oil is allowed.
Do doTERRA oils have an FEI clearance?
No. doTERRA's CPTG testing is a purity standard, not a competition clearance. The FEI does not certify essential oil brands, so a product's quality does not make it competition-safe.
What should I do if my horse tested positive after an oil was used?
Contact your veterinarian and your national federation immediately. Rule violations, even unintentional ones, require professional guidance, documentation, and a clear understanding of the substance involved.
Can I diffuse oils in a barn with competing horses?
We cannot give a blanket yes. Even diffusion can expose horses to airborne compounds, and the FEI rules do not care how a substance entered the horse's system. Confirm with your vet and federation before diffusing around competition horses.
The most important thing we can tell you is this: doTERRA oils can be a lovely part of your life with horses, but the FEI draws its own line. Purity earns trust for your own use. Compliance earns a clean competition record. Check the list, ask your veterinarian, and let the rules, not the label, guide what happens before show day.
