Scheid and Ellis (2016) also suggest this formula can be used for Heart Heat patterns with red or painful eyes, mouth ulcers, irritability and restlessness or nosebleeds, but also suggest if these are significant a formula like Dao Chi San or Xie Xin Tang might be more appropriate. Using this formula to treat these symptoms seems even less appropriate in the UK given the difficulty of replacing Mu Tong.
