Six days a week, in a small basement room in London's Soho, a Chinese herbalist called Dr Luo treats the first 50 patients who scrawl their names on a list taped to her door. They come from all over the world and most of them come with eczema. Amazed by her success, a specialist from Great Ormond Street Hospital embarked upon a unique project to bring the benefits of Dr Luo's medicine to his own patients. The story of this courageous collaboration reveals the problems that arise when western medicine tries to adopt an eastern remedy.
