When shopping for chamomile tea, consider going organic if it’s in your price range because herbicides can be used2 for weed control during plant cultivation.

Look for tea that has a certification (such as USDA Certified Organic) that supports the organic product label, and check the company’s website for evidence that it supports sustainable farming practices that consider worker health and safety. says Feller.

However, “it’s important that we don’t shame people for not buying organic—it may not be available or it may be available,” Feller adds.

If you use tea bags to get your dose of chamomile tea, you’ll also want to consider plastic and non-glue bags. These bags 17 were found to release billions of micro- and nanoplastics into your drink during the steeping process.

Once stocked up, store bagged chamomile tea in a cool, dark place according to package directions. Otherwise, store your chamomile tea in a tightly sealed container at room temperature and away from sunlight, which can help extend its shelf life, Feller says. “It’s best to store herbs away from extremes of temperature, humidity and light,” adds Robinette. “Once they dry, they won’t go bad, but they can lose effectiveness or strength after a couple of months on average.”

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