Ethnobotany of the Succulent Plant Genus Kalanchoe (Crassulaceae) in Kenya, East Africa

Succulent plants in the genus Kalanchoe hold significant biocultural value, yet inadequate information on their uses and identification constrains their utilization and management. This study set out to document the local names, distribution, and uses of Kalanchoe in Kenya, engaging 83 participants (32.5% female and 67.5% male) from nine ethnic groups (Kalenjin, Kamba, Kikuyu, Kisii, Luhya, Luo, Maasai, Mijikenda, and Taita) across six flora regions (K2-K7). Using purposive sampling and semi-structured interviews, the study revealed diverse uses of Kalanchoe, including treatment of sprains, swellings, wounds, gastrointestinal problems, as an analgesic, and against microbial infections in humans and poultry, relating to their pharmacological properties. The most utilised species are K. prittwitzii, K. densiflora, and K. lateritia, in that order. Threats such as agricultural encroachment and habitat loss underscore the urgency for in situ, ex situ, and agricultural conservation strategies to protect the biocultural heritage associated with Kalanchoe in Kenya.
