Due to their isolation and insufficiency of official medical care, the inhabitants of several Transylvanian “Csango” farms in Romania have valuable archaic knowledge of plants. Such ethnobotanical data reported previously from different regions of the country are available only in Hungarian. Of the various ethnic groups constituting the Csangos’ culture the present study was undertaken to survey those living in the Uz-valley (Romania), focusing on the indigenous human ethnomedicine and ethnoveterinary practices of Csinod, a village in the Eastern Carpathian Mountains. The aim of the study was to summarize the occurrence and diversity of food, medicinal, ornamental and fodder plants, as well as herbal home remedies applied on a daily basis. In the summers of 2007–2009 altogether 85 plant taxa in 13 home gardens were registered, using free interviews with local terminology, concentrating on drug parts, use, origin of knowledge and peculiar magico-mythological procedures associated with the species concerned. Due to the obvious decrease in the villagers’ traditional knowledge the prevention of these data from disappearing has gained primary importance in an effort to preserve this heritage as an integral part of the folk medicinal system in Transylvania.
