I had a chronic cough for a couple years, bronchitis a few months before, and had skin breakouts (which I called acne), and dry skin problem on my face, scalp and back. Over the course of two months my cough had completely disappeared, I no longer needed any herbs for my chronic cough, but I still had some flaky scalp and skin breakouts on my back. In time this also nearly cleared up. It was interesting to learn that in order to help the cough with Chinese medicine, it would also help the skin and vice versa.
