Cleavers (Galium aparine) is one of herbalism's most beloved spring tonics, treasured for centuries for its gentle, cooling support of the lymphatic system. Also known as goosegrass and sticky willy, this mild, grassy herb is traditionally used to encourage lymphatic drainage, ease fluid retention, and promote clear, healthy skin. It is a go-to herb for seasonal cleansing, urinary comfort, and sluggish, congested tissues. Naturally caffeine-free and easy to prepare — steep as a cold or warm infusion, or blend with nettle, calendula, or dandelion root for a nourishing spring detox tea.
