Laurel Plant in the UK: A Poisonous Danger to Horses

Laurel (Prunus species) is a common plant found in the UK, but it can be toxic to horses if ingested. Laurel contains hydrocyanic acid, a toxic substance that can cause serious health problems in horses. Excluding Bay Laurel, all other species of Laurel hedging are poisonous to horses and we recommend choosing Bay Laurel hedging if it is likely that horses may come into contact with your hedge. Otherwise, you may prefer to choose an alternative species.

Ingestion of laurel can cause a variety of symptoms, including respiratory distress, colic, excessive salivation, muscle tremors, and even death. The toxic effect of the hydrocyanic acid can be rapid, and death can occur within a few hours of ingestion.

It is important to be aware of the presence of laurel in your horse’s pasture or feed, as the plant is often overlooked as a potential hazard. Laurel is most toxic when it is in full bloom, but it can still pose a threat to horses even when it has matured and dried.

If you suspect that your horse has ingested laurel, it is important to seek veterinary attention immediately. Treatment will depend on the amount of the plant ingested and the severity of the symptoms, but can include medication to control symptoms, supportive care, and in severe cases, hospitalization.

To prevent exposure to laurel, it is recommended to remove the plant from your horse’s pasture or feed source, or to regularly rotate your horse’s grazing area to reduce the risk of repeated exposure.

In conclusion, laurel is a common plant found in the UK, but it can be toxic to horses if ingested. Horse owners should be aware of its presence in their horse’s environment and take necessary precautions to prevent exposure. If you suspect that your horse has ingested laurel, seek veterinary attention immediately.
