Classical Commentary on Jiegumu (Bone-Setting Wood)

From the *Ben Cao Xin Bian* (New Compendium of Materia Medica): "Jiegumu enters the joints, specializing in mending tendons and bones. For fractures, it can be taken with wine; for wind-damp itching, it can be used in a medicated bath. While its standalone power to mend bones and joints is truly remarkable, its bone-mending effects are even more extraordinary when used in combination with herbs that nourish and invigorate blood. It is most effective when used fresh. When dried, its potency is reduced by half, and stir-frying it further diminishes its power by another half."
