Alder bark is one of the most under rated, under used and under researched botanicals, in my opinion. Its traditional usage is found in most parts of the northern hemisphere. From England and Russia to Alaska and New Mexico, Alder Bark has a long history of use, for good reason. It has a powerful ability to cleanse the waters of our bodies. Much like how alder trees cleanse the waters along streams and riparian ecosystems, Alder cleanses our lymph and blood from impurities and stagnant toxins. Alder is cooling and mildly drying in action and is very grounding.
