Ethnobotanical survey and antimycobacterial activities of plants used against tuberculosis in Lubumbashi, DR Congo.
Article in Tropical medicine and health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTuberculosis is still a serious threat to public health in Africa and especially in the Democratic Republic of Congo, which is one of the eight countries with approximately two-thirds of the global cases of tuberculosis. Given the difficulties in accessing health care services and antitubercular treatments, indigenous population also uses plant-based traditional medicine. This study aimed to identify plants with antituberculosis potential in traditional Katangese medicine.
methodsInterviews were conducted on traditional healers using snowball sampling method. Ethnobotanical data were assessed by determination of the informant consensus factor and the relative frequency of citation. Guided field walks allowed to collect plants. Methanolic extracts were tested on Mycobacterium smegmatis and Mycobacterium bovis BCG using microdilution, diffusion and agar proportion methods. The cytotoxicity of the best extracts was evaluated by cell viability assay on the human cervical squamous carcinoma SiHa cell line. The 50% inhibitory concentration and minimal inhibitory concentration (MIC) were used to determine the selectivity index.
resultsThirty-eight plant species from 23 families were identified, most of which were from Fabaceae (16%). Eleven out of 17 plant extracts inhibited the growth of M. smegmatis at MIC ranging from 13 to 250 μg/mL. The methanolic extracts of Zanthoxylum chalybeum and Parinari curatellifolia showed MIC
conclusionsThe demonstration of antimycobacterial activity in the plants used in Lubumbashi against tuberculosis opens opportunities for more in-depth research into their chemical composition and toxicity, ultimately aiming to enhance their safety for treatment of tuberculosis.
