Adding honey to hot tea does not make it harmful.
The claim that heated honey becomes toxic derives from Ayurvedic tradition rather than from food safety research, and no credible evidence supports it at culinary temperatures. Heating does reduce volatile aroma compounds and enzyme activity, and raises hydroxymethylfurfural — a quality marker, not a safety threshold at these levels.
What this does not claim: This does not claim heating honey is without effect. Aroma is genuinely lost and expensive honey is genuinely wasted. It claims only that the safety concern is unsupported.
