Drugs used for asthma are a short-term solution providing long-term side-effects. Doctors are regularly prescribing inhalers to those with marginal problems, thereby converting a transient wheeze into a chronic condition which only ever-increasing doses of drugs can keep under control. In this work, Dr Mansfield examines recent research and presents his findings, offering practical advice and a programme of things that can be done to tackle the cause of the illness. He states that food sensitivities and candida are related and that indoor pollutants (fumes from gas cookers, carpets, paints, mites and moulds), which are exacerbated by hermetically-sealed modern houses, are a major cause of asthma, with outdoor pollutants forming only 5% of the cause.
