Mad Honey Poisoning: Symptoms and What to Do

Grayanotoxin poisoning is rarely fatal but it is genuinely dangerous, and it does not look like ordinary food poisoning. The pattern is a slowing heart, falling blood pressure, sweating and dizziness, sometimes hours after the honey was eaten.


If someone is unwell

If you are with someone who is faint, grey, confused, vomiting repeatedly or unable to stay upright, stop reading and call your local emergency number.

If you are unsure, your national poison centre will take the call, will not charge you and will not involve the police. Nothing on this site can assess a person; only a clinician can.
