Key Findings

  • The study in Quara, northwestern Ethiopia, documented 128 medicinal plant species used by local ethnic groups
  • Leaves were the most commonly used plant parts, and oral administration of plant extracts was the primary mode of remedy preparation
  • The study identified nine plants and 39 therapeutic uses not previously reported in Ethiopia, highlighting unique local knowledge
Ethiopia is a country known for its rich biodiversity, including a wide variety of medicinal plants. Many communities across the nation rely heavily on these plants for their primary healthcare needs. However, there has been limited documentation of this traditional knowledge in certain regions, such as the Quara district in northwestern Ethiopia. A recent study conducted by the University of Gondar aimed to fill this gap by documenting the indigenous and local knowledge of medicinal plant use among three ethnic groups in Quara[1]. The study, conducted from August 2022 to October 2023, utilized a comprehensive ethnobotanical approach. Data were collected through semi-structured interviews, field walks, and focus group discussions with 286 informants. Various sampling techniques, including snowball, purposive, and random sampling, were employed to ensure a diverse and representative sample. Quantitative analyses such as Rahman's similarity index (RSI), informant consensus factor (ICF), and direct matrix ranking (DMR) were used to analyze the data, along with descriptive statistics for basic ethnobotanical information. The researchers documented a total of 128 medicinal plant species from 112 genera and 50 families used to treat 14 disease categories. Notably, the Fabaceae family was the most represented, with 22 species. Trees accounted for the majority of the documented plants (37.5%), and leaves were the most commonly used plant parts (23.1%). The primary mode of remedy preparation and use was oral administration of plant extracts (56.7%). The highest ICF value (0.93) was recorded for circulatory and blood-related disorders, indicating a strong consensus among informants on the efficacy of these plants for such conditions. This study identified nine plants and 39 therapeutic uses not previously reported in Ethiopia, highlighting the unique medicinal knowledge in Quara. The RSI showed high overlap with neighboring areas, suggesting a shared ethnobotanical heritage, while low similarity with distant areas indicated regional specificity in medicinal plant use. The findings from Quara align with previous ethnobotanical studies in other parts of Ethiopia and Africa. For instance, a study in the Raya Kobo district of Northeastern Ethiopia documented 91 medicinal plant species used to manage various human and livestock ailments[2]. Similar to the Quara study, leaves were the most frequently used plant parts, and traditional knowledge was found to be rich and diverse. Another study highlighted the use of wild plants by pregnant women in Ghana and Benin, emphasizing the nutritional and medicinal properties of these plants[3]. These studies collectively underscore the importance of traditional medicinal knowledge and its potential contributions to healthcare. The Quara study also revealed significant threats to medicinal plant resources, such as agricultural expansion and fuelwood collection. These findings echo concerns from other regions where deforestation and environmental degradation pose risks to traditional knowledge and plant biodiversity[2]. The researchers recommend integrated conservation efforts to address these challenges and preserve valuable plant resources. In conclusion, the study conducted by the University of Gondar demonstrates the rich diversity of medicinal plants and associated traditional knowledge in the Quara district. The high ethnobotanical indices and unique findings warrant further phytochemical and pharmacological investigations to validate and potentially integrate these traditional remedies into broader healthcare systems. Conservation efforts are crucial to safeguard this important heritage for future generations.
