Red Maple Toxicosis

Red Maple Toxicosis

Acer rubrum (Red Maple) is a deciduous tree native to northeastern North America and commonly found near pastures. The leaves of A. rubrum, especially when wilted in the fall, cause severe oxidative damage to equine erythrocytes, leading to potentially fatal methemoglobinemia. Gallic acid and tannins from A. rubrum leaves have been implicated as the toxic compounds responsible for Red Maple Toxicosis (Boyer et al, 2002), but this study found that pyrogallol is a more potent inducer of methemoglobinemia.
