Book excerpt: This book makes an important contribution to our understanding of miasms and their place in classical homeopathic prescribing. The following statement from the foreword summarises its appeal -- "Generally it's rather easy to make a correct first prescription. Real difficulties mostly occur later on when the first remedy is not effective any more and only a few symptoms point to an exact following remedy." It includes information on miasms, diathesis, Bowel nosodes, Isopathic nosodes, energetic points, musle testing and various sample cases. The book emphasises on the fact that the only way in homeopathy to treat the negative information carried by chromosomes is by the use of classic and bowel nosodes which acts as a preventive approach against degenerative diseases like arteriosclerosis, coronary infarction, rheumatic diseases and diseases due to failure of the immune systems such as allergy, cancer, etc.,
