Background: homeopathy is held in organic agriculture as a means to control disease and plagues. However, different from doctors, who have works on materia medica and repertories available to choose the most suitable homeopathic medicine for each patient, agronomists do not yet have an equivalent Homeopathic Materia Medica of Plants (HMMP) describing symptoms observed in plants.
Aims: the aim of this study was to carry out a homeopathic pathogenetic trial (HPT) in plants comparing the effects elicited by boric acid in ponderable dose and dilution 6cH in two different plant species, namely bean and tomato cultivars.
Methods: 4 tests were carried out, 2 on tomato and 2 on bean plants, which received 1 to 6 applications of treatments.
Results: there were differences between both species regarding their sensitiveness to boric acid. None of the tomato plants that received Boron 6cH showed symptoms, differently from bean plants. On the other hand, in tests of ponderable doses of boric acid, tomato plants exhibited 3 symptoms more than bean plants. A higher number of bean plants exhibited symptoms with boric acid in ponderable dose than in dilution 6cH).
Conclusions: these results suggest that the elaboration of a HMMP must take into account the species in which symptoms were obtained. Moreover, HPTs in plants must be carried out with both ponderable doses and high dilutions in order for differences in sensitiveness among species be better identified.
