Monterey Bay Spice Company Slippery Elm Bark

European settlers learned how to use slippery elm bark from Native Americas, who used water-soaked strips as bandages. The dried herb is also traditionally prepared as tea, alone or in combination with chamomile, mint or other herbs. Slippery elm bark is also used to make infused oils, tinctures and liquid extracts.   Expiration Note: Amazon and Woot work hard to ensure that expired products are not shipped from Amazon fulfillment centers, but the nature of our business means that products with different expiration dates are shipped and thus we have no specific dates to disclose in advance.
