Heart-stopping 'mad honey' reportedly on sale online

Only the headline was available for this item — the article body was not provided, so the details below are limited to what the headline itself claims and should not be treated as a full summary. The piece, published by Phys.org and surfaced via Hacker News, reports that so-called ‘mad honey’ — a product associated with serious cardiac effects, up to and including cardiac arrest — is being sold through online channels. No specifics on the toxin involved, dosage thresholds, sellers, marketplaces, affected regions, or documented harm can be summarized here because the source text is missing. To generate an accurate, non-fabricated summary, supply the full article body and I will rewrite it in original prose.
