We assessed the diversity, knowledge, and use of antidiabetic
plants by traditional healers, plant traders, and
farmers from different locations in Benin. Altogether, 254
face-to-face interviews were conducted using a
semistructured questionnaire. Plant diversity was described,
based on species richness. Jaccard Index was used to
examine the similarity between locations. Consensus values
for plant part and manner of use were also computed.
A generalized linear model (GLM) with a Poisson distribution
was applied to assess the effects of social factors
on informants' knowledge. A total of 203 antidiabetic plant
species were mentioned, belonging to 176 genera and 72 families.
