Low Risk
Symptoms may include: Photo-sensitisation where the skin becomes sensitive to sunlight and develops small lesions on its surface which may allow infection to set in. Loss of appetite, debility, staggering gait and coma.
Notes: Low level poisoning is probably more common in Britain than is realised. Severe cases have been reported in horses. St John's Wort loses 80% of its toxicity when dried, but it can still be dangerous in Hay. |
