Could there be a miracle cure-all wonder drug? In a kitchen at the back of a trailer in the Arizona desert a Swiss bio-chemist has developed a herbal "cure-all" medicine, using traditional native American plants. He claims his miracle elixir has successfully treated diverse conditions from cancer and chronic fatigue to ulcers and baldness. And he says that he has the patients to prove it. When documentary film-maker Henry Murray had a lump in his neck diagnosed as being a potentially malignant tumour, he decided to try alternative medicine rather than risk a dangerous six-hour operation. He spent a month in the desert trying the medicine for himself, helping in its manufacture and meeting people who believed they had been cured.
