Alternative and Natural Approaches to Health and Wellness

Conventional medicines have proven highly effective at managing, minimizing, or even eradicating diseases in humans, but an increasing segment of the population is searching for less invasive, alternative, and more natural approaches to health and wellness. This trend is now overflowing into the equine world.

The growing interest in complementary or alternative modalities such as Chinese herbal medicines, acupuncture, massage therapies, chiropractic work, and homeopathy is allowing for a more integrative approach to horse health as veterinarians welcome these healing methods into their practice.

CHOOSING WISELY

Along with the growing interest in alternative treatments comes a lot of confusion, misinterpretation, or a general lack of education surrounding these approaches for horse owners. “There is a lot of information available on the internet, but also a lot of misinformation,” notes Kirsten Anderson, a veterinarian in Guelph, ON, who has a certification in equine acupuncture, veterinary spinal manipulatory therapy, and Chinese herbal modalities. “It can feel overwhelming to a client to know the best thing to do for a pet.” So how does a horse owner navigate through all the information, the plethora of products available, as well as the inherent discord between conventional and alternative therapies, in order to better understand the risks and benefits to their horse’s health?

First and foremost, get a proper diagnosis from your equine veterinarian so you know what you’re dealing with. “Do the workup and know what you’re treating,” urges Anderson. Attempting to treat a horse, whether by alternative or conventional treatments, without a proper diagnosis puts your horse at risk.

If you’re interested in alternative therapies, it’s highly recommended that you use an equine veterinarian who is certified in alternative therapies, or for massage or chiropratic therapy, a certified practitioner. The College of Veterinarians of Ontario provides a Position Statement that clarifies its position regarding the rights and responsibilities of providing complementary and alternative therapies in accordance with the Veterinarians Act. It’s important to understand that the vet has to let you know which conventional treatments are available first; in many instances, you may need to sign a form to agree to the alternative treatment, knowing there are conventional treatments available. If you decide to employ a non-vet to provide alternative treatments outside of the vet-client relationship, you do so at your own risk.

When you’re meeting with new practitioners, Anderson says it’s okay to ask for qualifications. A veterinarian in North America with training and credentials in alternative therapies can be verified through several websites, including the American Holistic Veterinary Medical Association website (AHVMA.org).

During your initial consultation, be prepared to reveal as much of your horse’s history as you know to the practitioner, including any changes you have noted and questions you want answered, suggests Dr. Joyce Harman, an equine veterinarian certified in equine acupuncture, chiropractic, and homeopathic treatments in a radio interview for Holistic Horse Radio. Gain an understanding of how the treatment will help your horse and how you can evaluate its effectiveness and outcome. With Chinese medicines, “There isn’t a one-size-fits-all remedy. There are large selections of formulas that need to be pieced together and each horse will react in a unique way to each one,” she states.

All members of your health team should be up-to-date and in the know with your horse’s health at all times. This is important to ensure that your horse is getting safe and effective treatment options. If you choose a practitioner who is not your regular vet, it’s advisable to inform your vet of what’s happening. “It’s always a good idea to consult your vet before you move forward with a product or modality,” advises Anderson. Moreover, “Be wary of claims about products or non-vets: when it seems too good to be true ‒ it usually is!”

ARE THERE RISKS?

There has been more research aimed at understanding the risks and benefits of herbal products, but to date it remains scant and relies mostly on testimony, antecdotes, or an extrapolation from human studies. “Many people believe that because herbs are ‘natural’ products that it also qualifies them as ‘safe’; however, evidence of various herb toxicities and negative side-effects has shown this to be a dangerous misnomer,” wrote researchers C. Williams and E. Lamprecht in their report Some commonly fed herbs and other functional foods in equine nutrition. “Herbs can have a drug-like action that can interact with other components in the horse’s diet. Unlike conventional veterinary medicines, which are well characterized with respect to bioactivity, toxicity, and contraindications, medicinal herbs are largely uncharacterized, with relatively unspecified and variable bioactivities.” Some herbs have the same biological effects as aspirin and NSAIDS (non-steroidal anti-inflammatory drugs) and when used together for long periods of time can have serious adverse effects to the animal. Williams and Lamprecht further stated, “Most herbs and functional foods have not been scientifically tested; this is especially true for the horse. Common [suppliers] for supplements like echinacea, garlic, ginger, ginseng, and yucca [may] not be regulated, and few studies have investigated safe, efficacious doses.”

CAVEAT EMPTOR

Many of the Chinese Herbal Medicines must be prescribed through a licensed veterinarian. But for the many non-prescribed supplements and ‘natural’ or herbal products that are available for purchase at retail outlets, Anderson says that buyers should be cautious: “Not all supplements and herbs are created equal. You need to understand what you’re buying and purchase your products from a reputable source, one where testing is done to assess purity and toxicity, quality of ingredients (e.g. how much filler is added) as well as accountability for labelling.” She adds, “If someone is selling a product and making claims, but they don’t have the credentials or [are not] collaborating with vets, that’s a red flag.”

If you are uncertain, Anderson advises clients to consult with their veterinarian or look for products with the National Animal Supplement Council Quality Seal on it, which tells consumers they are buying from a reputable company that has successfully completed a facility audit.

You can also refer to the Notification Products List through the Low-Risk Veterinary Health Products Interim Notification Program website (lrvhp.ca). Although health products sold for animal use aren’t well-regulated at this time, Health Canada is attempting to change this through the Interim Notification Program. Initiated in 2012 and ongoing, its goal is to obtain a higher level of quality control for low-risk natural health products sold in Canada for dogs, cats, and horses, including supplements, vitamins, minerals, TCM, probiotics, and homeopathic medicines. It’s a voluntary program in which an importer or manufacturer of a product can apply for a Notification Number (NN) through North American Compendiums (NAC), a third-party administrator. If the product meets the relevant conditions established by Health Canada, a notification number is issued, indicating that Health Canada has reviewed all of the active ingredients and evaluated the efficacy based on historical data, ensuring label claims are accurate and risk levels and guidelines are met. For a product to meet these standards, there are strict marketing claim guidelines where the product cannot claim to “cure cancer” or “reduce inflammation,” instead only general claims that refer to the maintenance of normal physiology such as “help maintain,” “support,” “promote,” “enhance,” “is a factor in,” “contribute to,” “has a role in,” etc.

COMBINATION TREATMENTS

Anderson says that her treatment approach depends on a number of factors. “I will often treat a horse with acupuncture first, and then treat with VSMT [veterinary spinal manipulative therapy] for areas of soreness that were not resolved by the acupuncture treatment. In a horse that has signs of mild stiffness/arthritis, I would consider a trial of an herbal product as a reasonable course of action if the owner’s preference was to use an herbal product over conventional drugs. If I have an animal that was in significant pain, however, then conventional anti-inflammatory drugs will make the horse comfortable much more quickly. In this case, an herbal product may be helpful as an adjunctive therapy, or to help keep the horse comfortable as the conventional drug is reduced or discontinued. Owners do need to be aware that in some cases there can be adverse drug/herb interactions, so it is best to consult with your veterinarian.”

She shares a personal experience. “One of my own horses is prone to sweet itch over the summer. During this time, I use an oral herbal product along with fly sheets to help reduce his itching. If I find that this is not enough to keep him comfortable, then I start him on an antihistamine. By doing this, I have been able to manage his condition without the use of corticosteroids, which have the potential risk of inducing laminitis.”

We all want to provide the best care for our equine partners and alternative therapies are certainly proving a viable option. “There is a place for both; you still need to know what you’re treating, but alternative approaches can be very beneficial under the right circumstances and under the expert care of the right practitioner,” advises Anderson. With an arsenal of knowledge and reputable care from a licensed equine practitioner, you don’t have to take it with a grain of salt but instead, perhaps, with a teaspoon of turmeric.

COMMON NATURAL THERAPIES

Homeopathy

Homeopathy originated in the late eighteenth century with the German physician Samuel Hahnemann. It is believed that homeopathic remedies stimulate the body’s own healing processes, based on the idea that substances that produce symptoms of sickness in healthy people will have a curative effect when given in very dilute quantities to sick people who exhibit those same symptoms. (For example, using ipecac, which induces vomiting and causes gastrointestinal distress, to treat a person with similar symptoms.) Even though these extremely diluted remedies may have no chemical trace of the original substance at all, practitioners believe that the electromagnetic energy of the original substance is retained, while the toxic side-effects of the remedy are not. This electrochemical “message” stimulates the body to heal itself.

Acupuncture

“Horses are one of the species that respond the best to acupuncture,” states Anderson. “The acupuncture points are located in areas that have an increased number of blood vessels and nerve bundles. When needles are placed, they cause micro-trauma to the tissue which stimulates the nervous system, resulting in changes in the body that cause the release of hormones and endorphins and stimulates the flow of energy, or ‘Qi.’”

Acupuncture can be used to improve overall movement and treat musculoskeletal issues, coughing in horses with COPD, help manage pain in laminitic horses, reduce hives, and help stimulate gut motility in cases of colic. Anderson warns, “Horse owners should be aware that acupuncture is not an instant fix. Multiple sessions are usually needed before the ailment or injury is healed.”

As it is considered a medical procedure, only licensed veterinarians with specialized training should perform equine acupuncture; according to the College of Veterinarians of Ontario, individuals who practice on humans are not licensed to practice on animals unless under the direct supervision of a vet.

Chiropractic

Chiropractic, or veterinary spinal manipulative therapy (VSMT), works by restoring normal motion to a joint, including those in the spine and also in the legs. A joint not moving through its full range of motion (vertebral subluxation) can be treated using a short-lever, high-velocity thrust in a specific direction. Human chiropractors who have taken additional training in animal chiropractics are allowed to treat horses.

“One horse I treated was a quarter horse mare who was short-striding behind and was tight in her lower lumbar region,” says Anderson. “VSMT helped to loosen up her lower back and subsequently her short-striding resolved, improving her hind end movement.”

Herbal remedies

A 2009 study of racing Standardbreds published in the Canadian Veterinary Journal demonstrated the benefit of herbs in several equine disorders including recurrent obstructive pulmonary disease, allergic dermatitis, and joint inflammation, in addition to modulating immune responses in healthy horses.

Chinese Herbal Medicine (CHM) has been around for over 3,000 years. Contrary to conventional western medicine that treats specific symptoms with pharmaceuticals, surgery, or other methods directly, CHM looks at the body as a whole ‒ psychological, physical, and social ‒ and is based on the belief that disease is a result of physical, emotional, spiritual, social, and environmental imbalances. CHM relies on acupuncture, treatment with herbs, and Tui Na (acupressure/massage) used separately or jointly.

“I have found that herbal remedies can be helpful in some cases of recurrent airway disease, helping to calm or reduce anxiety, and for treating some cases of arthritis,” notes Anderson. “Xiao Yao San is one Chinese herbal formula that I have used successfully in a mare who was prone to anxiety and irritability. This formula contains phytoestrogens and is thought to have both an estrogen-balancing and calming effect.”

Western herbs used to treat arthritis include white willow bark, meadowsweet, devil’s claw, turmeric, and hawthorn. The TCM formula Xiao Huo Luo Dan is composed of six different herbs that work synergistically in the treatment of acute arthritis, soft tissue injuries, and back pain.

Massage therapy

Massage therapy can be helpful to improve performance, increase suppleness, and improve mobility by releasing muscle tension in the body and relieving muscle soreness.

Tui Na, or Chinese meridian massage, ranges from being vigorous deep massage and manipulation to gentle superficial massage. The Thumb Pressure Technique is used in sensitive areas where more intense pressure could be harmful, such as the horse’s neck. Crossed-Hands Pressure can relieve tension in larger muscle-mass areas, such as the horse’s shoulders and hindquarters

THE GREAT VACCINE DEBATE

Vaccinating your horse has become a hot topic. When Horse Sport conducted an informal on-line survey, the results showed that 17% of horse owners choose not to vaccinate.

The great debate over whether to vaccinate our horses is a tricky one to navigate while maintaining respect for both sides. Vaccination has effectively eradicated or severely diminished the occurrence of many deadly infectious diseases, such as polio and small pox in humans and tetanus and sleeping sickness in horses. However, opposition to vaccines raises concern over adverse reactions and unnecessary need for an already immune-protected animal.

The Ontario Ministry of Agricultural, Food, and Rural Affairs (OMAFRA) provides guidelines for vaccinating horses. They are neither mandatory nor legally binding, just a starting point for horse owners and veterinarians to discuss their appropriate use as part of a disease prevention program. Most vets will recommend the ‘core’ vaccines, those that will protect your horse from diseases that are endemic to your region, pose a significant public health risk, are highly infectious, or can cause severe disease. This includes rabies, tetanus, eastern and western equine encephalomyelitis, and West Nile virus.

Much of the belief that vaccinations are dangerous results out of fear, misinformation, or when stories are shared. While there have been no legitimate studies that link vaccination to an over-stimulated immune system such as headshaking to allergies, there can be adverse reactions such as local swelling, fever, nasal discharge, temporary blindness, blood platelet deficiency, muscle wasting, and even colic. The AAEP cautions horse owners from abandoning a vaccination protocol altogether, instead suggesting that in cases where side-effects are experienced to pre-medicate the horse with an anti-inflammatory to prevent or lessen the reaction. Another suggestion would be to split the vaccines up over several weeks.

Most horses are vaccinated annually or semi-annually for at least the core vaccines, but the question remains: are we over-vaccinating our horses? There is increased interest to perform vaccine titre testing in order to assess the immunologic status of the animal against certain infectious diseases. A titre test is a laboratory test measuring the level of antibodies in the blood, which are produced when an antigen (a virus or bacteria) provokes a response from the immune system. Titre tests are available for equine herpes III (rhinovirus), Potomac horse fever, equine encephalitis (EEE, WEE and VEE), equine influenza, equine viral arteritis, rabies, West Nile virus, strangles, and Lyme disease. A titre test may run you around $150, compared to the vaccine at around $20.

Veterinarians caution horse owners that this is just one piece of a big immunity puzzle. “A positive titre result does not guarantee your animal is protected ‒ it’s just an indication,” notes Anderson. And if you travel with or show your horse, or are considering a new barn, test results alone may not be accepted.
