Mares, Am I Right?!
Spring can be a difficult time for the mares in the herd, and for those of us that have to deal with them. Their tenacity and grit is why we love them, but sometimes they are just too much.
There are many wonderful herbal and nutraceutical options specifically designed for these ladies on the market that can significantly support their health and well-being. Most of these products contain the same essential herbs, though they come in different ratios to suit individual needs. What particularly interests me is the common overuse of Raspberry leaf and the noticeable under-use of chasteberry. Both of these herbs have their distinct place in equine health management, yet almost everyone tends to reach for raspberry leaf when addressing issues related to the mare-ish behavior, often without fully understanding its effects. Meanwhile, Chasteberry, is frequently overlooked despite its valuable benefits.
The first up: Raspberry leaf. Raspberry leaf, scientifically known as Rubus idaeus, is a very common ingredient in a wide variety of mare supplements, but it’s actual function is frequently overlooked in discussions about equine health. Its historical uses encompass strengthening and toning the uterine muscles, assisting with contractions during the foaling process, as well as effectively checking the progression of hemorrhaging and encouraging the cleansing of the afterbirth. However, there doesn’t seem to be anything here about helping with the unpredictable and often troublesome cycles, is there? I do firmly believe it has merit if you suspect your mare is suffering from cramping akin to what women experience. Many studies are readily available that note the benefits of Raspberry leaf; these discuss it’s efficacy based on the combination of fragarine, an alkaloid component found in raspberries, and tannins, which are naturally occurring polyphenols often identified in wine. Together, they are known for their effectiveness in treating PMS symptoms, particularly those bothersome issues such as cramping, vomiting, nausea, and diarrhea.
Chasteberry, scientifically known as Vitex agnus-castus, may be the more suitable herb depending on your mare's specific needs. This herb, widely regarded as the PMS herb for humans, offers several notable benefits. When taken as needed, Chasteberry serves as an effective anti-inflammatory agent that also assists in calming hormonal fluctuations and alleviating mood changes associated with premenstrual syndrome (PMS) in humans. It is often noted for its ability to make difficult mares more manageable and has demonstrated some calming effects on aggressive stallions as well. Additionally, Chasteberry has been linked to improved pregnancy success rates, although it is important to note that it should not be used during pregnancy. An exciting aspect of this herb is its reputed capacity to support the functioning of the hypothalamus and pituitary gland in horses. According to various studies, it can aid in shedding, decrease fatigue while enhancing energy levels, and help to reduce pain in equines.
When looking in to “Mare” supplements, be aware of what the ingredients actually do. Herbs are medicine, and some herbs can disrupt the absorption or efficacy of pharmaceuticals. Always check with your vet if your horse is on any medication before starting an herbal regimen.
