Black Poplar

Scientific Summary

Black Poplar (Populus nigra) is a deciduous tree whose bark, leaves, and roots have been used in herbal medicine. The extract is applied for its mild anti‑inflammatory and soothing properties, and the bark is traditionally used to support heart health, reduce swelling, and calm irritated skin. The plant is generally safe when used externally; however, ingesting large amounts of bark or root can cause mild gastrointestinal upset, and caution is advised for those with kidney issues or on blood‑thinning medications.
