摘要：Pharmacognostical study of the 28^^^ chapter of the Lalangue's book Medicina ruralis Uliti Vrachtva ladanyszka was performed. This chapter is a botanical dictionary named Od kazitela vrachtveneh trav ovde zadersaneh zkratkem preopominanyem {The register of the herbal remedies presented in the book with short explanations). The material for the pharmacognostical study comprised 159 remedies, mostly herbal, which belong to 50 herbal families. We established that there were 125 well known plants and/or drugs, 13 unknown or obsolete herbal drugs, 11 inorganic substances and 10 animal remedies. The lexical units of the plant dictionary were classified and explained, with certain supplements in therapeutical and pharmacognostical fields. We tried to find out the importance of herbal drugs in Croatian medicine of the 18^^ century. We also discussed about obsolete drugs as well as about remedies which are in medical use for centuries but somehow they are not mentioned in the Lalangue's book. After investigation of Medicina ruralis Uliti Vrachtva ladanyszka we can conclude that Lalangue had a great influence and that he gave a large contribution to the medicine of that time. But also new questions have been opened which lead us to new investigations of Lalangue's work.
