The data presented in this article is in support of the research paper "Medicinal plants and their uses recorded in the Archives of Latvian Folklore from the 19th century" [1]. This article provides the list of plant species and disorders treated with medicinal plants mentioned in the records of Latvian folk medicine and used by indigenous people of Latvia in the 19th century. In total, the data include 211 genera belonging to 71 plant families. The accepted scientific names of plant species, plant parts used, dosage forms of herbal medicines, and routes of administration are reported in the table. Plant uses are grouped into one of the 17 categories based on the body systems and psychological and social problems. The frequency of citations is indicated for each use of medicinal plant.

Medicinal plants and their uses recorded in the Archives of Latvian Folklore from the 19th century.

ETHNOPHARMACOLOGICAL RELEVANCE: The records of folk medicine present historical evidence of medicinal plant usage in the territory of Latvia and describe native and imported plants and plant products that were used as medicine. AIM OF THE STUDY: To collect and analyse the ethnobotanical knowledge found in records of Latvian folk medicine available in the Archives of Latvian Folklore. MATERIALS AND METHODS: Following the International Classification of Primary Care, plant uses were grouped into one of the 17 categories based on the body systems and psychological and social problems. Each plant was identified by its scientific name according to The Plant List website. Additionally, the plant parts used, dosage forms of herbal medicines and routes of administration were analysed. RESULTS: In total, 211 genera belonging to 71 families were mentioned in the analysed materials. The most common health conditions were digestive system disorders, respiratory system disorders and skin disorders. The plant families with the largest number of taxa were Asteraceae, Rosaceae, Lamiaceae, and Apiaceae. The most frequently mentioned native plant taxa were Achillea millefolium L., Matricaria chamomilla L., Allium cepa L., Artemisia absinthium L., and Plantago sp. L. Leaves and flowers were the most commonly used parts, and herbal tea was the most common dosage form. Only 59 out of 211 taxa mentioned in this study are included in the official herbal monographs of the European Medicines Agency. CONCLUSIONS: One hundred and fifty-two plant taxa mentioned in the records of Latvian folk medicine are not included in the European Union herbal monographs providing scientific information on the safety and efficacy and deserve further exploration as traditional herbal medicines.
