The color of each symptom follows the severity scale above.
Trifolium hybridum, the alsike clover, is a species of flowering plant in the pea family, Fabaceae. The trifoliate leaves are unmarked and the stalked, pale pink or whitish flower head grows from the leaf axils.
There is limited evidence of T. hybridum having toxic effects on horses including photosensitization and Alsike clover poisoning. Photosensitivity in horses, also known as alsike rash, is a reversible condition in which the mechanism is unknown. A diet in equestrians of at least 20% T. hybridum over the course of four weeks could lead to poisoning which includes deleterious neurological effects and liver failure. The active toxin is unknown. The plant can irritate skin if handled.
Also recorded as Hybrid Clover and Swedish Clover.
