Plants have been used as a traditional medicine for many years for the people of Wolaita, Ethiopia. The aim of the study was to record the local knowledge of the peoples who inhabit the Diguna Fango district. A semi-structured interview was conducted with a total of 60 informants. Totally, 50 species belonging to 24 families were identified to treat 28 human and livestock ailments. Solanaceae (14.3%) was the most abundant family whereas; the Rosaceae (1.00) had the highest family use value (FUV). Most of the plants (82%) were reportedly used to treat human diseases. Herbs (34%) were the dominant growth habits, followed by trees (33%). The leaves (30%) were identified as the most used plant part. The most common methods of remedy preparations were eating and chewing (18.2% each) followed by grinding (13.61%). Oral (73.3%) was the major route of administration, followed by dermal (21.7%). The cardiovascular system diseases category (1.00) had a higher informant consensus factor value followed by the fever disease category (0.90). Croton macrostachyus Hochst. ex Delile, Commelina benghalensis L., Triticum dicoccon (Schrank) Schübl. and Pentas arvensis Hiern (100%) had a higher fidelity level to treat swelling, chirt (skin diseases), weight gain and bone fractures, respectively. Persea americana Mill. was ranked highest as the most preferable medicinal plant for various purposes by local people, followed by Acacia abyssinica Benth. The principal threatening factors reported were charcoal production (26%), agricultural expansion (15%) and firewood (14%). Out of the plants and their uses documented, 16% of the medicinal plants and 28.6% of the uses were novel. The present study showed the existence of indigenous knowledge of medicinal plants to treat human and livestock ailments. Therefore, there should be mentoring for the local people in the study area to conserve their indigenous knowledge and resources.

“…Repellents are substances that act as area repellents (at a distance) by deterring insects from flying to, landing on or biting human, or are applied to exposed skin and clothing for protection ( Brown and Hebert, 1997 ; Blackwell et al., 2003 ; Choochote et al., 2007 ). Many natural products are safe for humans when compared to synthetic chemical pesticides ( Sharma and Ansari, 1994 ; Regnault-Roger et al., 2012 ; Wendimu and Tekalign, 2020 ). Property utilized repellents are an inexpensive means of reducing or preventing arthropod-borne diseases and nuisance biters on a wide range of vectors ( Gupta and Rutledge, 1994 ).…”

The repellency effect of smoke from burning Azadirachta indica, Eucalyptus camaldulensis and Ocimum forskolin plants to reduce human-mosquito biting activity. Ground mixed powders of the plant leaves produced smoke by direct burning and thermal expulsion on the traditional stoves in experimental huts against An. arabiensis and Ae. aegypti. A four-by-four Latin-square design was used to assign treatment and control experimental huts over different nights. In the treatment huts, the percent repellency of the smoke produced by burning powdered plant mixtures of the plants were determined by reduction mosquito density. There was a reduction on An. arabiensis (93.75%, P < 0.001) and Ae. aegypti (92%, P < 0.001) respectively, for huts with burning powder versus no treatment. Overall, plant mixed powders tested by both methods of application offered significant protection (>90%) against both mosquito species tested and has the potential to be used as an alternative mosquito control method.

“…It is estimated that nearly 6000 plant species with popular therapeutic usage in Africa [27]. About 80% of the people in the country use raw medicinal plants to meet their primary health care needs.…”
