Poverty and poor sanitation in sub-Saharan Africa are the main reasons for parasitic infection prevalence. Medicinal herbs have been sources of natural and cheaper remedies for the treatment of many parasitic infections, including intestinal parasites. The study aimed to document medicinal herbs used in treating intestinal worm infections in the Ibadan metropolis through an ethnobotanical survey. The three main traditional herb markets, Oje, Oja Oba and Iwo Road, in Ibadan city, were purposively selected for the survey. The respondents, who were mainly herb sellers, were interviewed using structured questionnaires. The information obtained included demographic information, names of plants used in the treatment of worms, plant parts, dosage and method of preparation. The data collected was analysed using descriptive statistics and the Relative Frequency Citation (RFC), Use Value (UV) and Informant Consensus Factor (ICF) of the mentioned plants were calculated. The survey revealed 45 plants that are used in the treatment of intestinal worms in Ibadan. These plants belong to 31 families. The most frequently mentioned plants with their RFCs were Cryptolepis sanguinoleta (Lindl.) Schltr (0.39) and Aristolochia albida Duch (0.39) while most of the plants belong to the Families Apocynaceae and Euphorbiaceae. The roots (25%) and the leaves (18.75%) were the most commonly used plant parts. Most of the plants were indicated to be used singly while some were used in combinations of two or more. The study has revealed the medicinal plants that are used against intestinal parasites. Thus, bioassay studies to confirm the claims should be carried out to establish the activities of these plants.
