With the changeable weather, there are sniffles in the office as well as the stables, and the simple use of essential oils may just help keep some of those bugs at bay.

Your horse’s body often gets compromised by microorganisms. Aromatherapy can be used to help your horse with any infection, however it is adjunctive to your horse’s veterinarian care, so the suggestions in this article are for your information and not to replace his advice.
Microorganisms that cause disease are called pathogens and can include bacteria, fungi and viruses. They can cause infection and they actively reproduce causing damage to healthy cells, often being responsible for producing toxins in the body. Infection can be systemic where it speads thoughout the body, or localised, and when your horse’s body responds to an infection, the severity of this response is displayed by the symptoms you see. With the use of essential oils we aim to strengthen your horse’s own defence system and lessen the intensity of symptoms so your horse can recover with less stress as his body destroys the offending microorganisms.
Early recognition of an invader is important for any treatment to be effective. Your horse’s body is designed to minimize attack of its body by microorganisms. As orifices are often the points of entry they are designed to keep the body protected. Eyes have tears to wash away microorganisms, mouths fend off invaders with mucous membranes and alkaline saliva, the hairs in the nostrils minimize entry of microorganisms, the respiratory tract secretes mucous to trap microbes, the urinary system contains healthy bacteria to prevent harmful microorganisms taking hold, the stomach and intestines produce acid, enzymes and beneficial bacteria that destroy unfriendly bacteria, and even the sebaceous glands of the skin secrete chemicals which are highly toxic to bacteria. It is important when we use essential oils we assist these natural barriers, and not compromise their function.
Essential oils in themselves all have varying anti-microbial properties. Depending on their chemical makeup, they will be more effective with different microorganisms, however to some degree all essential oils exhibit anti-bacterial, anti-fungal, anti-viral properties. They act to directly oppose threatening microorganisms and help build a healthier body resistant to attack.
Bacteria are what we commonly refer to as germs. They can include the bacteria Clostridium tetani, which causes tetanus and Streptococcus equi, which causes strangles. Your horse’s body will attempt to fight invading bacteria and sometimes this is successful without treatment, but in some cases your horse may need an antiserum, such as with tetanus, or anitbiotics as in bacterial pneumonia.
Essential oils such as tea tree, Melaleuca alternifolia, have been shown to be very effective in helping fight Streptococcus bacteria in human trials. When a horse has been infected with this bacteria and you need to quarantine him, regular diffusion of a blend of essential oils inculding tea tree will assist the infected horse with his battle against this invader. An immune-building blend to help your horse if this is an issue would include tea tree, bergamot (Citrus bergamia), and lavender (Lavendula officinalis or angustifolia). If other horses have come in contact with an infected horse before his quarantine, you can also strengthen their immune systems by diffusing their stalls with a similar blend.
Not only would these essential oils inhibit the progress of the bacteria, they would also assist any horse healing with the stress of confinement. Simply add 5% of equal parts into a bottle of distilled water with a dash of alcohol or detergent to help disperse the essential oils and spray the horse’s stable throughout the day. Alternatively these essential oils could be added to an electric diffuser undiluted and left to disperse throughout the day and night to support the animal.
With any wounds where your horse may have come in contact with the bacterium responsible for tetanus, you can use tea tree essential oil to wash the wound while monitoring the horse and checking with your veterinarian if further treatment is necessary.
Fungi are relatively simple invaders, however they can penetrate into the tissue of the horse. One common fungal infection is ringworm. Your horse can also suffer fungal infection of gutteral pouch from the fungus Aspergillus. Tea tree oil is also highly antifungal and our first choice as an essential oil when it comes to fungal infections. Patchouli, Pogostemon patchouli, is also a highly antifungal essential oil and useful applied to skin fungal infections. A lesser known antifungal essential oil is manuka, Leptospermum scoparium, a native of New Zealand and often referred to as the New Zealand Tea Tree, it is similar in scent yet softer, though this does not diminish its action. Another essential oil from the same family is niaouli, Melaleuca viridifolia. Each of these essential oils may be applied undiluted to small areas, less than one square inch, or on larger areas in aloe vera gel.
Viral infections can include something as simple as a wart to extremely serious diseases such as rabies, as well as a cold virus. Viruses can be inhaled in droplets or swallowed in food or water; they may also be passed through the saliva of biting insects, or may enter the horse’s body durig covering/breeding.
We have a wide selection of antiviral essential oils including Eucalyptus globulus and Eucalyptus radiata, which are useful in fighting adenoviruses responsible for the common cold. Introducing eucalyptus in a body rub or diffused in the air can assist the body to produce white blood cells to help it fight infection. When it comes to localised infections such as warts we can look at topical applications of lemon, Citrus limonum, which can be applied undiluted to small warts or in aloe getl to larger areas. Lemon is not photosensitive, especially the essential oil obtained by distillation, so it is safe to use ocer a period of time no matter what time of theyear you are working with your horse.
Building up Your Horse’s Immunity
It has been shown in human health that for those who are exposed to and use essential oils regularly, their immune systems are more finely tuned and often fend off attack by invaders with little effect on the body. I have seen this with horses that have regular aromatherapy sessions or where owners incorporate aromatherapy into a weekly grooming routine.
Most essential oils from the Myrtaceae family are anti-infectious and can be used around your horse to protect him from any disease that may be circulating in your area. They include Cajeput (Melaleuca leucadendra), niaouli, clove (Eugenia caryophyllata), Eucalyptus, and Myrtle (Myrtus communis). They will also assist the sick horse with his battle to overcome disease states.
The regular use of essential oils such as bergamot, which is also antiviral, and lavender, ravensara (Ravensara aromatica), thyme (Thymus vularis), pine (Pinus sylvestris), palmarosa (Cympopogom martini), kunzea (Kunzea ambigua) will not only help build your horse’s immune system, it will also create a barrier in the form of negative ions. When there are plenty of negative ions in the air, it is more difficult for any invader to move unimpeded through the air.
Blue cypress (Calitris intratropica), lemon eucalytus (Eucalyptus citriodora), lemon myrtle (Backhousia citriodora), lemon tea tree (Leptospermum petersonii) can also make effective insect repellents, offering limited protection from disease-spreading mosquitoes while also helping your horse build his immune system.
As an aside, the scent of an essential oil, once inhaled, is filtered by the limbic system of the brain and then this information is fed on to the hypothalamus gland. The hypothalamus gland in turn then sends out instructions to the endocrine system, whereby each gland in the body is affected and given a “tune-up.” It is the glands that help keep the immune system healthy. With this in mind the use of any essential oils will help your horse maintain a stronger and healthier immune system.
