Herbal Support for Mares

Mares can be wonderfully expressive, sensitive and subtle. Herbal support should always respect the mare in front of you, not label every behaviour as “hormonal”.

Botanical supplements for nutritional support — not medicines, treatments, cures, or a replacement for veterinary care.

Start by observing the pattern

Mare behaviour can change with the seasons, with management, with discomfort, with stress or with pain. Before reaching for a supplement, it helps to keep a short diary. Note the date, behaviour, ridden work, turnout, feed changes and any signs of physical discomfort. Patterns matter.

Herbs traditionally used for mares

Raspberry leaf is one of the best-known herbs used in mare routines. Chasteberry is also widely discussed for seasonal mare support and older horses, although it should be used carefully, especially where medication or diagnosed endocrine issues are involved. Chamomile and vervain are often selected for sensitive mares where the aim is to support settled behaviour and relaxation. Nettle can provide gentle nutritional support.

Avoid overclaiming

It is tempting to say a herb will balance hormones, but responsible wording is more careful. A better way to think about mare herbs is that they may support normal seasonal balance and comfort as part of a wider management routine. They do not replace veterinary checks, saddle fitting, dental care, bodywork or sensible training.

Pregnant and breeding mares

Do not feed herbs to pregnant or lactating mares without professional guidance. Breeding, pregnancy and lactation are specialist areas, and even gentle-sounding herbs may not be suitable. Always seek veterinary advice.
