These same anti-inflammatory benefits can have a protective effect on internal organs. When researchers examined sumac for intestine damage and failure, they found sumac is a promising treatment for preventing these injuries. Sumac has antioxidants, immune support, and helps prevent cell death. Another 2009 study concluded sumac benefits help protect against organ and DNA damage.
Sumac can even help with muscle pain after workouts. A randomized trial in Physiology International gave one group sumac juice daily. The sumac group had less pain and better workout recovery compared to their non-juicing counterparts. Researchers found sumac reduced inflammation and helped with pain.
