Ethnomedicinal knowledge of plants used in alternative medicine as uterotonics in Lubumbashi, Haut-Katanga, Democratic Republic of Congo.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTraditional medicine constitutes a principal component of primary healthcare in Democratic Republic of Congo (DRC), particularly in Lubumbashi. However, ethnobotanical knowledge related to its use remains incompletely documented and underutilized. The present study aimed to systematically document medicinal plants used as uterotonic among residents of Lubumbashi.
methodsEthnobotanical data were collected through structured interviews with 207 informants (housewives, 𝑛 = 103; herbalists, 𝑛 = 26; traditional healers, 𝑛 = 78; sex ratio M/F = 0.5; mean age 35.6 ± 4.3 years; mean professional experience 13 ± 4.2 years).
resultsInformants cited 98 medicinal plant species, predominantly trees (38 species), distributed across 43 botanical families, with Fabaceae being the most represented family (16 species). Malaria was the most frequently reported non‑uterotonic indication (46 species). A total of 122 traditional oxytocic formulations were recorded; most involved leaves (43 recipes) and were principally administered as cataplasm (44 recipes). To our knowledge, 34 species were reported for the first time with oxytocic uses, of which eight are documented for the first time as medicinal plants in DRC. Among taxa, Hylodesmum repandum (relative citation frequency, RCF = 0.20) and Crassocephalum montuosum (RCF = 0.19) exhibited the highest citation frequencies, while Securidaca longepedunculata (use value, UV = 0.27) and Hibiscus sabdariffa (UV = 0.25) showed the greatest overall use values.
conclusionThese findings provide a baseline inventory for pharmacological, phytochemical, and toxicological studies, and support prioritization of bioassay-guided validation and conservation strategies for culturally important species.
