MEDICINAL PLANTS USED TO TREAT HUMAN AND LIVESTOCK DISEASES IN DODOLA DISTRICT, WEST ARSI ZONE, OROMIA REGIONAL STATE, ETHIOPIA

ABSTRACT

Medicininal plants have been used for the treatment of human and livestock ailments

since ancient times.The study was conducted to investigate the medicinal plants used

to treat human and livestock diseases in Dodola district, West Arsi Zone, Oromial

above the age of 20 were randomly selected through simple random sampling

technique.Data were collected using semi structured interviews, field observations and

focus group discussions.Data were analyzed using descriptive statistics frequency and

percentage, preference ranking, paired comparison, direct matrix ranking, informant

consensus, and informant consensus factor, fidelity level index and jaccard’s coefficient

of similarity. A total of 128 medicinal plants belonging to 114 genera and 56 families

were documented. The Asteraceae family had the most species with 14 (10.9 %),

followed by Solanaceae with 12 (9.39%). Of these 86 species were used for the

stomachache while paired comparison showed Croton macrostachys the most

preferred species in treating febrile illense. Eucalyptus globulus was shown the most

multipurpose use species while agricultural expansion was considered as major threat

to plants in general and medicinal plants in particular. Hence, raising awarness is vital to

save medicinal plants from further loss.
