Dragon’s blood resin (Xue Jie) is often classed as a herb for external application, but is also taken internally, usually as a powder. It enters the blood level of the Liver channel to invigorate the blood, disperse stasis, and stop pain, and is used for blood pooling due to internal injuries, contusions from falls, stabbing pain in the chest and abdomen, and gynecological conditions such as amenorrhea or postpartum pain due to blood stasis.
