Red willow bark comes from the Salix laevigata tree, commonly found in North America. This tree is known for its distinctive red stems and is often found near water sources. The bark has been traditionally used by various Indigenous peoples for its medicinal properties. The bark contains compounds similar to those found in aspirin, which may help reduce pain and inflammation. It has been used in herbal remedies for headaches, muscle pain, and other ailments. However, scientific research on its effectiveness is limited, and it is important to consult a healthcare professional before using it for medicinal purposes.
