It is dried plant matter; without moisture there is nothing for harmful organisms to grow on. You may be underwhelmed by a flat, aromaless cup, but that is not illness, just disappointment.\nDamp and mouldy: yes, potentially\n\nSource: Teas.co.uk.

Canonical: https://teas.co.uk/wiki/can-old-tea-make-you-sick/The genuine risk is mould. If tea has taken on moisture, from a humid kitchen, a leaky pack, condensation, it can grow mould, and drinking visibly mouldy or musty tea can make you unwell. This is the one scenario where the answer is a firm yes and the action is the bin, immediately, no rescue attempt.\nHow to recognise the danger\n\nSource: Teas.co.uk.

Safe-but-stale signs: looks normal, dry, just smells faint and brews weak. When the two are hard to tell apart, err to the bin, see can you drink old tea.\nBrewing does not fix it\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Brewing does not fix it, Can Old Tea Make You Sick?. Canonical: https://teas.co.uk/wiki/can-old-tea-make-you-sick/Boiling water does not make mouldy tea safe; it does not undo spoilage and you would still be drinking the off product. \"Brew it stronger to mask it\" is exactly the wrong instinct. Spoiled is spoiled, see does tea go off.\nPrevention is the whole answerBecause the only real risk is moisture, the entire defence is moisture control: opaque airtight tin, cool dark dry cupboard, away from steam and the kettle, bought in amounts you will drink, see how to keep tea fresh and how to store tea. Do that and this question never becomes real.\nIn a sentenceDry old tea will not make you sick, it will bore you. Damp, mouldy tea can, and goes straight in the bin.
