The presented paper provides a comprehensive survey and evaluation of medicinal plants described in the veterinary literature of the 18(th) and 19(th) century as used for the treatment of sheep and goats. A range of 40 books on sheep- and goat-diseases was covered and 381 bibliographical data were evaluated. One aim of this study is to possibly enlarge today's selection of phytopharmaceutic remedies. Symptoms and diseases have been sorted on a pathological classification. The plants surveyed have been evaluated following a certain scheme. Six categories of evaluated plants per indication could be stated: (1) plants still used in veterinary medicine, (2) plants recommended for clinical tests in sheep and goats, (3) plants providing a supporting activity, (4) plants with effects still unexplored, (5) noxious or toxic plants, (6) plants without therapeutic activity. The evaluation of the plants surveyed was carried out according to pharmaceutical standard literature, in addition the rather rare veterinary phytotherapeutic literature was used. These publications provided the information of the therapeutic values of these plants. As a result some medicinal plants were recommended for future clinical studies especially on diseases of sheep and goats. More knowledge about these medicinal plants would reveal their usefulness in today's phytotherapy.
