Description:
Red maple is a tree with 3-5 lobed leaves that are palmately veined. In autumn the leaves turn red, purple, or orange. The inflorescence is an elongated cluster composed of smaller clusters of male and female flowers that are usually red. The fruit is a samara (often called "helicopters" by children). The wood is used for furniture, cabinets, and flooring.
Toxic Part: The wilted leaves are reportedly toxic.
Toxin: Unknown
Symptoms: Consumption of wilted red maple leaves has been reported to cause severe illness and death in horses. Clinical signs of red maple poisoning include depression, anorexia, difficult or labored breathing, jaundice of the whites of eyes (yellowing), and an increase in heart rate. Horses that consume wilted red maple leaves often develop hemolytic anemia which is characterized by red blood cell destruction in the spleen or bloodstream.
Treatment: Recommended treatment includes supportive care for symptoms and denying animal access to red maple leaf material. Plumlee suggests blood transfusions for the anemia if it is severe. If however, the animal is in renal failure, this treatment may not be effective.
