He is not OK. I had threatened abortion (bleeding) and my friend suggested me visiting herbalist so finally I visited him. However, what made me shock was the Chinese medicine he asked me to drink... "gui san" (i.e, dong gui) and "chuan kung". I drank one time and found bleeding became more serious so I finally gave up. Finally, I changed to visit the herbalist whom I always visited. He told me both of gui san and chuan kung made my bleeding more serious and shouldn't drink any more. If I knew gui san is same as dong gui, I wouldn't have drunk it as even I know dong gui can't be drunk whenever "there" bleeds.
