I just want to share my experience with this Dr.
My daughter cough for very long time, I went to this Dr with Herbs for 5 months, spent $14K and also introduce some friends to this Dr. In fact, he is quite expensive.
At the beginning, it seems to be a bit effective, however, from time goes on, I can only say, she've got a bit improve, but still can not stop her cough. Dr just also said changed Herb again and again. My conclusion is my daughter need to change another Dr. This is only my experience, hope it can help Mums who is suffering now. :-(
