Feeding Raspberry Leaves To Your Horse

Raspberry leaves have long been used in herbal medicine, but their role in equine care is gaining traction thanks to both tradition and emerging science. Whether you're managing a moody mare, a reactive gelding, or a broodmare preparing for foaling, raspberry leaf might be the herbal support your horse needs. I started using them for my horse Finn as a way to reduce his anxiety from track trauma.

What Are Raspberry Leaves?

Raspberry leaves come from the Rubus idaeus plant and are rich in magnesium, tannins, flavonoids, and antioxidants. These compounds contribute to muscle tone, hormonal balance, and nervous system support—making raspberry leaf a popular choice in natural equine supplements.

Is This Backed By Research?

As typical with most natural supplements in the horse world direct studies on horses are limited for raspberry leaf usage. However, research on raspberry leaf compounds and their effects in other animals and humans provide compelling insights:

  • Hormonal Regulation: Raspberry leaf has been traditionally used to support reproductive health. Studies on Rubus species show uterine toning effects and potential benefits for gestational health in mammals[^1].
  • Anti-inflammatory & Antioxidant Properties: Research on Rubus coreanus and Rubus corchorifolius (related raspberry species) has identified terpenoids and flavonoids with anti-inflammatory and immune-modulating effects[^1].
  • Hypoglycemic Effects: Raspberry leaf extracts have shown blood sugar-lowering effects in diabetic rats, suggesting metabolic benefits that may extend to equine health[^1].
  • Veterinary Use: Raspberry leaf is listed among medicinal plants used in British Columbia for reproductive health in pets, including horses[^1].

These findings support using raspberry leaves as a calming, hormone-balancing supplement—especially for mares during heat cycles and broodmares during pregnancy.

Why Use It For My Horse?

  • Mares in Heat: Helps reduce irritability, muscle cramps, and sensitivity during hormonal cycles.
  • Geldings with Attitude: Supports emotional stability and reduces reactivity.
  • Broodmares: Promotes uterine health and may aid in smoother foaling.
  • Stressed Horses: Offers non-drowsy calming support for travel, training, or competition.

How Do I Give It To My Horse?

Horses may eat raspberry leaves because they are rich in vitamins and minerals and can act as a natural supplement, but it's best to feed them dried and cut leaves in moderation. Avoid feeding the fresh, green leaves or giving large amounts, and never give them to mares in the first nine months of pregnancy due to potential risks. A typical dose is around ½ cup of dried raspberry leaf daily. I split this into morning and night. Finn loves the taste and will actually eat them out of my hand.

Note: Always consult your vet before introducing new supplements. Ensure leaves are fully dried—partially wilted leaves may contain high tannin levels that can irritate the digestive tract[^2].

Personal Experience Too!

When I first started working with Finn he had quite a bit of anxiety under saddle. We had done extensive bonding, ground work and trust work but I think he associated being ridden with some trauma he experienced at the track. At first I just gave it to him pre-ride. It really helped "take the edge off" so he could focus and learn that I wasn't going to ask him for anything that he couldn't manage. It doesn't dull their senses or make them groggy.

Where Can I Get It?

Final Thoughts

Raspberry leaf is more than a folk remedy—it’s a scientifically supported, vet-approved supplement that can enhance your horse’s mood, comfort, and performance. Whether you're managing hormonal swings or seeking a natural calming aid, this humble herb might be the key to a happier horse.

Peace and Good Rides,

Laura
