Scientific Name: Hypericum perforatum
Toxicity: Toxic to Horses
Toxic Principles: Hypericin
Clinical Signs: The adult plant is not very palatable, but can be ingested if suitable forage is unavailable; the young plant is attractive and may be grazed in abundance. The toxic component is light-active, and causes a chemically induced sunburn, usually within 24 hours after ingestion on light, unpigmented areas of skin. Dermatitis, itching and ulceration of the skin leading to skin damage are possible effects.
