When shopping for chamomile tea, consider choosing an organic option if that’s in your price range, as herbicides may be used2 to control weeds during the plant’s cultivation.

Look for a tea that has a certification (such as USDA-certified organic) that backs up its organic label, and consider scouting the company’s website for evidence that it supports sustainable farming practices that take worker health and safety into consideration, says Feller.

However, “it’s important that we don’t shame people for not purchasing organic options—it may not be readily accessible or affordable,” adds Feller. 

If you’re using sachets to get your dose of chamomile tea, you’ll also want to consider plastic- and glue-free bags. These bags have been found17 to release billions of micro- and nanoplastics into your drink during the steeping process.

Once you’ve stocked up, store your bagged chamomile tea in its packaging in a cool, dark area according to package recommendations. Otherwise, store your chamomile tea in a well-sealed container at room temperature and out of sunlight, which can help extend its shelf life, says Feller. “It’s best to store herbs away from temperature changes, humidity, and light,” adds Robinett. “Once dried, they won’t go bad but can lose efficacy or potency after a couple of months on average.”

Brewed tea can be stored in the fridge for up to two days; after that, it may start to ferment and taste sour, says Feller.
