Other Information:

Su Mu, from the Sappan Wood tree, was originally exported from Southeast Asia during the 17th century and is used in traditional Chinese medicine. When the wood of the sappan tree is freshly cut, it is yellow in color, but quickly turns to the vibrant red color associated with the Su Mu herb. When put in hot water, the color leaks quickly and within 8 hours the extract will be a deep orange color. 

The Su Mu herb has been used to ease abdominal pain postpartum, as well as pain from fractures, falls, and sprains. It also can be used to stop bleeding. Su Mu is known to reduce inflammation and open the channels while harmonizing the Blood. It should not be used during pregnancy or when Blood Stasis is not present.
