• Same functions as the bark, though generally stronger overall, more moving to the Qi, and promotes the free flow of stagnant liver Qi.
• Primarily for depression, constrained emotions, irritability, insomnia, especially when accompanied by epigastric pain and feelings of pressure in the chest.
• There are at least four different plants used as this herb, including albizzia flower, which consists of many pink hairs when fresh and becomes brown when dry, and several unrelated others. Many practitioners prefer the substitute species to the “true” herb.
