Plants Toxic to Horses- Horse Tails
2007 K. Blocksdorf
The soil around my old property is largely sand and gravel. It drains quickly, making it the perfect for this variety of horsetail. Other varieties grow in more marshy areas. If the plant is dried into hay the toxin may have a greater effect than in the fresh plant. The toxin in this plant destroys the Vitamin B in the horse's blood.

Symptoms of Horsetail poisoning are:

  • weakness
  • stumbling
  • arrhythmia of increased pulse
  • death
  • irritability

If you suspect poisoning from any plant or substance call your veterinarian immediately.
