Can old herbal tea make you sick?

Properly stored, dried herbal tea does not become unsafe with age — it simply loses aroma and flavour. The exception is tea exposed to moisture, which can develop mould and should be discarded.

Is it okay to drink herbal tea past its best-before date?

Generally yes. A best-before date reflects peak quality, not safety — the tea will likely taste milder but is not inherently unsafe if it shows no signs of moisture or mould.

How do I know if my tea has gone bad?

Look for visible clumping, a musty smell, or any sign of mould. A faded aroma alone just means the blend is past its best, not spoiled.

Does Herbal Tea Go Bad? Shelf Life Explained

Herbal tea won't make you unwell once it's old — but it will stop tasting like much. Here's the difference between "expired" and simply tired.

Dried, not perishable

Properly dried botanicals have very little residual moisture, which is what makes them shelf-stable in the first place. Unlike fresh food, they don't have a hard point at which they become unsafe to consume.

What changes over time is aroma and flavour, not safety. The volatile oils that give a blend its scent and taste dissipate gradually, so an old blend tends to become bland well before it becomes questionable.

What actually causes tea to spoil

The exception is moisture. If a blend is exposed to damp — steam from a kettle, a humid cupboard, an improperly resealed pouch — it can develop mould, and that is a genuine reason to discard it rather than simply expect a milder cup.

Visible clumping, a musty smell, or any sign of mould are the clear signals to throw a blend away. A simply faded aroma is not.

'Best before' vs. 'use by'

A best-before date on dried tea is a quality marker, not a safety cut-off — the manufacturer's estimate of when the blend stops being at its peak, not a point after which it turns.

This is different from a use-by date on fresh food, which is a genuine safety boundary. Loose-leaf herbal tea, stored correctly, is generally fine to drink well past its best-before date.

Getting the most from an older pouch

If a blend has faded, a slightly longer steep or a slightly fuller measure can bring some of the character back, though it won't fully restore what's been lost to time.

The better approach is simply pacing purchases to what you'll get through in six to twelve months, so every cup is closer to its best.
