Hormonal Regulation:

Chasteberry is known for its ability to support the regulation of the pituitary gland and hormonal balance. It helps to increase the secretion of dopamine, which in turn can reduce the production of prolactin, a hormone involved in lactation and other reproductive functions.

This can be particularly useful for mares with irregular estrus cycles, stallions with overly aggressive behaviour, or geldings exhibiting hormonal imbalances.

It can also help horses with mares in heat or those showing mood swings associated with hormonal fluctuations.

Behavioural Support:

Horses exhibiting aggressive behaviour, irritability, or frustration, particularly in geldings or stallions, may benefit from chasteberry. Its ability to balance hormone levels can help reduce mood swings, aggression, and frustration associated with excess testosterone or other hormones.

Managing Mare’s Heat (Oestrus):

For mares who experience difficulties during heat cycles, chasteberry can help to regulate the hormonal fluctuations that contribute to behaviours like mood swings, irritability, or frequent urination. Some mares that have excessive or prolonged oestrus cycles may benefit from chasteberry as part of a holistic approach to managing this issue.

Supports the Pituitary Gland:

Chasteberry’s action on dopamine receptors can help support the function of the pituitary gland, which plays a central role in regulating hormones throughout the body. In horses with conditions like PPID (Pituitary Pars Intermedia Dysfunction, also known as Cushing’s disease), chasteberry may be used as part of a broader management plan to help support the pituitary gland and balance hormones.

How Chasteberry Works:

Chasteberry primarily affects dopamine production in the brain. Dopamine is a neurotransmitter that inhibits the release of prolactin and other hormones that may be out of balance. By increasing dopamine levels, chasteberry helps restore normal hormonal function, particularly in horses suffering from hormone-related issues.

Dosage and Administration:

• Dosage can vary depending on the horse’s weight, age, and the issue being treated. Generally, 10–30 grams per day of chasteberry powder is the recommended dose for most horses, but it’s important to follow the manufacturer’s instructions or consult your veterinarian for specific guidance.
• The dosage may be given over a period of weeks to months, and the response will often be gradual. Some horses may show improvement within a few weeks, while for others, it might take longer.

Chasteberry for Specific Conditions:

• Mare Reproductive Health: For mares that experience irregular heat cycles or significant discomfort during oestrus, chasteberry can help balance hormones and reduce irritability or discomfort.
• Behavioural Issues in Geldings and Stallions: Horses with hormonal imbalances may show aggression or frustration. Chasteberry can help moderate these behaviours by regulating testosterone levels and restoring hormonal balance.
• PPID Management: While not a treatment for Cushing’s disease (PPID), chasteberry can be part of a complementary management plan for horses with PPID to help regulate pituitary function and balance hormone levels.

Chasteberry is a natural herb that can help manage hormonal imbalances in horses, particularly those related to reproductive health, mood swings, and behavioural issues. It is a useful option for mares, geldings, and stallions experiencing hormonal fluctuations or conditions like PPID.
