Abstract
ABSTRACT: An ethnobotanical study of medicinal plants was conducted between
October 2009 and April 2010, in Ofla Wereda of Southern Tigray, Ethiopia. The study
employed common ethnobotanical methods including semi-structured interviews, field
observations, preference ranking, paired comparisons and informant consensus. A total
of 84 informants from 12 Kebeles (7 informants from each Kebele) were selected
randomly and 36 key informants with the help of local administrators, recommendations
from elders and members of the local community. In this study, 113 traditional
medicinal plants were collected and identified. These species represent 95 genera and
51 families. The family Asteraceae with 12 species (10.62%), Lamiaceae and
Solanaceae with 11 species (9.73%) each were commonly used medicinal plants in the
study area. From the total of 113 medicinal plants, 82 species (72.57%) were used to
treat human ailments for 55 health problems, 16 species (14.16%) were used to 14
livestock health problems and the remaining 15 species (13.27%) were used to treat
both humans and livestock diseases. Herbs are the most used plants, accounting for 52
species (46%), shrubs 34 species (30.1%) and trees 27 species (23.9%). Leaves, roots,
and fruits are the most used plant parts accounting for 68 species (45.3%), 31 species
(20.7%) and 18 species (12%) in that order. Fresh plant parts from 74 species (65.5%)
are frequently used in the study area than dried plant materials (27 species, 23.9%) and
both dry and fresh materials (12 species, 10.6%). From the collected traditional
medicinal plants informants reported that species used as crushed preparations were 39
(26.2%) followed by pounded which were 34 (22.8%) and those used as fumigants were
20 (13.4%). Most herbal preparations are administered externally compared to internal
