Ethnobotanical Study of Medicinal Plants Used in the Treatment of Diseases in the Kangu Grouping

Abstract

Aims: This study aimed to establish a systematic ethnobotanical inventory of medicinal plants used by vendors and traditional healers for the treatment of human diseases in the Kangu community, Democratic Republic of Congo. Specifically, it sought to identify the main afflictions treated, the most frequently used plant parts, and the predominant modes of preparation and administration. Study Design: A descriptive ethnobotanical survey based on structured questionnaires and statistical analysis. Place and Duration of Study: Conducted in the Kangu Grouping between January and June 2025. Methodology: Data were collected from 30 respondents, including traditional healers and herbal vendors, through structured questionnaires and interviews. Plant species were identified and therapeutic indications categorized. Descriptive statistics were applied to analyze citation frequencies, plant parts used, and preparation modes. A total of 67 medicinal species were documented. Results: The respondents reported 67 species used to treat 40 afflictions grouped into 10 categories. Malaria emerged as the most frequently cited condition, followed by gastrointestinal disorders and reproductive health issues. Leaves were the most commonly used plant part, while enemas and oral intake represented the predominant modes of administration. Conclusion: This study provides a baseline ethnobotanical inventory of medicinal plants in the Kangu community, emphasizing their cultural and therapeutic relevance. The findings highlight species of potential pharmacological interest and underscore the importance of preserving traditional knowledge. They also open new avenues for validation and safe integration of local remedies into future clinical research, while promoting sustainable use of biodiversity.
