Different honeys, different questions
Mad honey vs manuka honey.
Manuka honey comes from the mānuka plant. Mad honey is associated with grayanotoxin-containing nectar, including certain rhododendrons. The similar names do not describe the same product. MPI: manuka identity · Utah Poison Control: mad honey

The differences at a glance
| Question | Mad honey | Manuka honey |
|---|---|---|
| Botanical source | Nectar containing grayanotoxins, including certain Rhododendron species. | Mānuka (Leptospermum scoparium). |
| Key identification question | Does evidence establish the product, origin and current batch’s tested content? | Does the honey meet the claimed botanical identity and applicable labeling requirements? |
| What the name does not prove | Safety, a predictable concentration or a safe serving size. | That the jar is a medical dressing or treats an illness. |
| Testing to understand | A report tied to the current product and batch, identifying measurements and laboratory. | New Zealand’s export identity definition uses four chemical markers and one DNA marker. |
| Distinctive safety issue | Grayanotoxin poisoning can cause low blood pressure, slow heart rate, nausea and vomiting. | Evaluate the actual food label and your health needs; do not apply medical-device claims to food jars. |
What manuka testing establishes
New Zealand requires honey labeled as manuka for export to meet a scientific identity definition and be tested by a recognized laboratory. The definition combines four nectar chemicals and a DNA marker from manuka pollen to distinguish monofloral and multifloral manuka. It is an identity test, not a grayanotoxin scale. Read MPI’s testing requirements.
What matters with mad honey
Utah Poison Control describes grayanotoxin poisoning as a cause of low blood pressure, slow heart rate, nausea and vomiting. Toxicity depends on the toxin content. A fixed spoonful, origin label or brand’s “strong” description cannot establish a safe amount. Read the toxicology case review.
Our mad honey brand profiles show seller source links, testing claims and information gaps. They do not independently certify the honey or recommend a dose.
Food honey and medical dressings are different products
The FDA database includes a specific gel dressing with active manuka honey. That is a regulated device record for that product; it is not a treatment claim for any jar labeled “manuka.” Use the instructions for an appropriate medical product and seek clinical advice for wound care.
