Horses, like humans, face a wide range of health issues, from skin conditions to joint pain, digestive problems, and more. While veterinary care is essential in treating most serious conditions, many horse owners are turning to natural remedies to support their horses’ health and well-being. Before adding any of these natural remedies, consult with your veterinarian to determine if it is the best option for your horse. Most natural supplements lack FDA approval because there isn’t enough research to support their effectiveness or safety. While these supplements may offer potential benefits, there are no established guidelines for proper dosages or administration. Therefore, it’s important for consumers to educate themselves before using them. These holistic treatments focus on using natural ingredients and methods that have been used for centuries to promote healing and improve quality of life.

1. Herbal Remedies for Digestion
Because horses are designed to graze constantly, digestive problems are common, especially in horses that experience stress, travel, or changes in diet. Natural herbs can help promote gut health and ease digestive discomfort.
- Slippery Elm: This herb is known for its soothing properties and can help alleviate symptoms of colic, ulcers, and other digestive issues. It works by coating the stomach lining and aiding in the healing process. It has been shown in a 2020 study to reduce contractility of nonglandular gastric smooth muscle from pigs and may indicate a protective effect of this nutraceutical in horses with mechanically induced gastric ulcers. More equine research is needed for positive evidence.
- Peppermint: Known for its anti-spasmodic effects, peppermint can help relieve bloating and gas, making it useful for horses with colic or indigestion. You can also add peppermint oils to water to encourage drinking and increase the palatability of unfamiliar water when traveling. Evidence in other species indicate that there are benefits, like reduced nausea in dogs, but more equine specific research is needed.
- Aloe Vera: Research indicates that aloe vera can help soothe the digestive tract and is rich in compounds such as polysaccharides, which have anti-inflammatory and immunomodulatory effects, and may help in the healing of gastric ulcers, a common issue in horses, especially those under stress. Aloe vera also contains enzymes that may assist in the digestion and absorption of nutrients. However, excessive amounts can lead to laxative effects, which may result in diarrhea or other digestive disturbances.
2. Joint and Muscle Support
As horses age, joint problems like arthritis and stiffness can become a concern. While veterinary interventions like joint injections and medication are commonly used, natural remedies can be effective in maintaining joint health and reducing discomfort.

- Turmeric: This golden root contains curcumin, a potent anti-inflammatory compound that can help alleviate joint pain and inflammation. It has become popular as a natural remedy for arthritis in horses and is often combined with black pepper to enhance absorption.
- Devil’s Claw: This herb has been used for centuries to treat joint pain and inflammation. It is especially helpful for horses with arthritis or lameness, as it has pain-relieving properties. This is often found on the ‘banned substances’ list for many equine organizations.
- MSM (Methylsulfonylmethane): MSM is a naturally occurring sulfur compound that supports joint health, reduces inflammation, and improves flexibility. It is often included in natural joint supplements for horses. There is suitable evidence that MSM has positive results for horses.
- Glucosamine and Chondroitin: Glucosamine and chondroitin support joint health by helping repair cartilage and maintain its elasticity. They are often used to alleviate joint pain, stiffness, and inflammation in horses, particularly those with arthritis or heavy work. Research shows they can promote cartilage repair and improve joint function.

3. Skin and Coat Care
Horses can suffer from a variety of skin issues, from minor irritations to more serious conditions like rain rot, mange, or dermatitis. A healthy shiny coat begins with a high-quality diet. Many topical natural ingredients can help soothe the skin, promote healing, and enhance the condition of their coats.
- Aloe Vera: Aloe is widely used for its cooling and healing properties. It can be applied topically to soothe sunburn, minor wounds, or skin irritations. Aloe vera also promotes faster healing of cuts and abrasions. Aloe is a safe natural remedy to include in your treatment of minor wounds.
- Coconut Oil: Rich in fatty acids, virgin coconut oil is great for moisturizing dry, flaky skin. It can also be used to promote a shiny, healthy coat when fed. Coconut oil possesses antimicrobial properties that can aid in the healing of cuts and scrapes. Studies on rodents treated with virgin coconut oil have shown accelerated wound healing. Consult with your vet or equine nutritionist to determine the amount of coconut oil to feed.
- Lavender Oil: Lavender is not only known for its calming aroma but also for its antiseptic and anti-inflammatory properties. It can be applied topically to minor cuts, scrapes, or insect bites to speed up healing and reduce irritation. Always apply with a carrier like coconut oil and be mindful of potential allergic skin reactions with you and your horse.
4. Immune System Boosters
A healthy immune system is essential for keeping horses free from illness and disease. Natural remedies can help support and strengthen the immune system, especially during stressful times or when a horse is recovering from an illness or injury.
- Echinacea: This herb is renowned for its ability to stimulate the immune system and help fight off infections. It is often used to prevent illness and support recovery. Corticosteroids medicines can counteract the effect of this plant.
- Spirulina: Spirulina offers significant immune-boosting benefits for horses due to its rich nutrient profile, including vitamins, minerals, and antioxidants. It contains high levels of beta-carotene, vitamin E, and phycocyanin, all of which help to enhance the immune system’s response to infections and diseases.
- Vitamin E: Vitamin E is essential for immune support in performance horses because it is a powerful antioxidant. Vitamin E supports the production and activity of immune cells, such as T-lymphocytes and macrophages, which are critical for fighting infections and responding to injuries. Horses that may benefit from supplementation include those without access to pasture, performance horses undergoing intense work, breeding horses, and those diagnosed with neurological conditions such as equine motor neuron disease (EMND) or equine protozoal myeloencephalitis (EPM).
5. Stress and Anxiety Relief
Horses are sensitive creatures, and stress can significantly impact their health and behavior. Natural remedies can help calm anxious horses and improve their emotional well-being.
- Roman Chamomile: Chamomile has calming properties and can help reduce anxiety and stress in horses. It is often used to help with issues like separation anxiety, travel stress, or general nervousness. Roman Chamomile has been shown to be effective in muscle relaxation while at rest.
- Valerian Root: Valerian is a natural sedative that can be used to calm anxious or hyperactive horses. No studies have been done in horses, but one study found that when given to pigs, there was a sedative and anti-anxiety effect.
- Lavender and Lemon Balm: Both of these herbs have a calming effect on horses and can help ease stress. Lavender can be used in aromatherapy or applied to the skin, while lemon balm can be fed to the horse as a tea.
6. Fly Control and Pest Repellent
Horses are often plagued by flies, mosquitoes, and other pests, especially in warm weather. Instead of relying on chemical repellents, many horse owners are turning to natural alternatives to keep their horses pest-free.

- Citronella Spray: Some studies have shown that this mixed as a spray reduces the annoyances of pests like flies. Citronella has been used to repel biting and sucking insects like mosquitos.
- Neem Oil: Known for its insect-repelling properties, neem oil can be used as a natural alternative to chemical fly sprays.
- Garlic: Adding garlic to the horse’s diet can make them less attractive to insects, as garlic has natural insect-repelling properties. However one study showed garlic supplemented horses to have slightly declining hemoglobin values.
Final Thoughts
Natural remedies can be a valuable tool in supporting a horse’s health and well-being, but they should be used thoughtfully and in conjunction with traditional veterinary care. Always consult with a qualified veterinarian before starting any new natural treatment, especially if your horse has an existing condition or is on medication. The United States Equestrian Federation cautions against the use of herbal and natural products because they can result in a positive detection of prohibited substances when drug tested. The ingredients and properties of products to be classified as prohibited are included but not limited to valerian, kava kava, passionflower, skullcap, chamomile, vervain, leopard’s bane, night shade, capsaicin, comfrey, devil’s claw, hops, laurel, lavender, red poppy and rawuolfia. By integrating these holistic approaches with a balanced diet, regular exercise, and proper veterinary care, horse owners can provide their horses with the best possible care for a long, healthy life.
