Mad honey and blood pressure: who should never take it
Mad honey lowers blood pressure and slows heart rate, but this is a toxic effect, not a treatment — the drop is unpredictable in size and it is the same mechanism behind grayanotoxin poisoning. Anyone with a heart condition or low blood pressure, and anyone taking blood-pressure or heart-rate medication, should not take mad honey at all, because the effects stack dangerously in the same direction.
Why it affects blood pressure
Grayanotoxins act on voltage-gated sodium channels in nerve, cardiac and vascular tissue. In practical terms that means the compound acts directly on the cardiovascular system: reported effects at higher doses include a marked fall in blood pressure and a slowed heart rate (bradycardia). This is well documented in the medical literature — but it appears there as a description of poisoning, not of a therapy.
Do not use mad honey to manage blood pressure
It is sometimes marketed for this. That is both unsupported and dangerous: the size of the drop is unpredictable, it is a toxic effect rather than a controlled dose, and combining it with actual blood-pressure medication can push you too far. We mark sellers down for making this claim.
Who should never take it
- Anyone taking antihypertensives (blood-pressure medication) of any kind.
- Anyone on beta blockers or calcium channel blockers, or other heart-rate or rhythm medication — the effects add up.
- Anyone with a heart condition, arrhythmia, or naturally low blood pressure.
- Anyone who has fainted from low blood pressure before.
- Anyone pregnant or breastfeeding, and anyone under 18.
If you are unsure whether a medication you take affects heart rate or blood pressure, ask a pharmacist before going anywhere near mad honey.
Why not with alcohol
Alcohol also lowers blood pressure and impairs coordination. Combined with mad honey, the risk of fainting and injury rises. Keep them completely separate.
Warning signs that need medical help
Fainting or near-fainting, chest pain, a pulse that feels very slow or irregular, persistent vomiting or confusion. Seek medical attention and say exactly what was eaten and how much — grayanotoxin poisoning is treatable when the cause is known. If in doubt, call your local poison control service. See the how much is too much guide.

Frequently asked questions
Does mad honey lower blood pressure?
Yes, but as a toxic effect with an unpredictable magnitude — not a treatment. It must never be used to manage hypertension.
Can I take mad honey if I'm on blood pressure medication?
No. The effects act in the same direction and can stack dangerously. Avoid it entirely and ask a pharmacist if unsure about any medication.
Is mad honey good for high blood pressure?
No. Marketing that says so is both unsupported and dangerous. The drop it causes is a poisoning effect, not a controlled dose.
What are the cardiovascular symptoms of too much mad honey?
Low blood pressure, a slowed or irregular heart rate, dizziness and fainting. These are the reasons it is not a 'ride it out' substance — seek help.
