At least 12% of children are affected by asthma, and at least 90% of children with asthma have inhalant allergies. Some of this may be due to food intolerance, and a tendency to bronchial hyper-reactivity seems to be genetically determined. A case is described of a family who all have allergies of some description. The daughter, Janie, now aged 9 is treated for asthma conventionally using inhalers and steroids. An osteopath, a homoeopathic physician and a practitioner of traditional Chinese medicine then each describe how they would treat Janie and the expected outcome. The homoeopathic physician would conduct an in-depth interview and prescribe a constititutional remedy, 3 doses only, to be taken all on the same day, at 30c potency. He would take skin tests to test for allergies to house dust, pollens, feathers, fur and moulds. Ten days after the first remedy he would prescribe the worst of her allergens at 30c. Conventional medication would not be removed and would only be reduced very slowly on improvement. When weaning a patient off steroids, it is helpful to use a homoeopathic potency of Cortisone. After one month, reassessment is necessary if there has not been good improvement, although a correct homoeopathic prescription can last for several months without needing to be repeated. The likelihood of great improvement is very high.
