Homeopathy is based on the principle of cure by similarity and on the prescription of minimal doses and single medicine to healthy individuals. In plants, performing treatments on the basis of drug dynamisation has increased in the recent decades. In these treatments, it is necessary to conduct a pathogenetic experimentation in order to apply homeopathic principles and to consolidate homeopathic plant material. Through a pathogenetic test with bean plants treated daily by pulverization and irrigation, using diluted and dynamized essential oil of Eucalyptus citriodora - (dilutions: 0.5 and 1%) (oil dynamisation: 12 and 30CH) -, there appeared external symptoms similar to those symptoms caused by Pseudocercospora griseola, i.e., the causal agent of angular leaf spot of bean. The pathogenetics study with E. citriodora raises the possibility of its application to control angular leaf spot in bean plants in accordance with the homeopathic principle of cure by similarity.
