Abstract:
Background: in a previous paper we reported the statistical analysis and other distribution data of a
homeopathic pathogenetic trial (HPT) of Plumbum metallicum 30cH carried out by our group. However,
at that time we did not report the resulting pure materia medica, i.e., the totality of symptoms elicited
by the tested medicine on healthy volunteers. Aim: to communicate to the homeopathic community
the full record of symptoms collected in our HPT of Plb. Methods: methods to collect and select
symptoms have been reported in the previous paper. In synthesis were excluded all previous common
symptoms of volunteers, even with slight differences, and selected only those that were really unknown,
never seen, unusual or very strange for the prover. In this paper special emphasis was given to new
symptoms as well as unusual or repeated dreams, while in the previous paper special emphasis was
given to repeated and crossed symptoms. Results: symptoms are reported in their chronological
order of appearance in each volunteer. 37 new symptoms were found, useful to update Homeopathic
Repertories. It is also included a synthesis of the original HPT of Plb carried out in 1828 in order to
make available the full experimental materia medica currently existing. Conclusions: the new HPT,
besides widening the pathogenetic picture of Plb (skin and mucosae symptoms), also allowed us to
give new and deeper meanings to some of the symptoms reported in the original trial, such as Anxiety,
Activity, Depression, Slowness, Gastro-oesophageal problems, Colitis. The dreams complete the
remedy image, mainly in work, religion and sexual themes. Up to the present time there is no peerreviewed
publication devoted to HPTs. For this reason, researchers are compelled to publish HPTs
as private editions. This results in poor control of the quality of publications and a lack of standards
on how to present the results of HPTs.
