The utilization of medicinal and psychoactive plants in the past represents a pivotal intersection of culture, health, and biodiversity. While such plants in Arabia have been known from classical and medieval textual records, this study provides material evidence of the use of one such plant for fumigation already in the Iron Age. Through metabolic profiling of organic residues recovered from archaeological artefacts at the oasis of Qurayyah, Northwest Arabia, we identified the drug plant Peganum harmala. Renowned for its antibacterial, psychoactive and multiple therapeutic properties, its presence highlights the deliberate utilization of local pharmacopeia by ancient communities. This discovery represents not only the first evidence for its use in Iron Age Arabia, but also the most ancient, radiometrically dated material evidence of Peganum harmala being used for fumigation globally. Beyond their health benefits, these plants were also valued for their sensory and affective properties. Documenting, understanding and preserving these ancient knowledge systems enriches our understanding of ancient traditions while safeguarding the region's intangible cultural heritage.

BACKGROUND: Reinwardtia indica, a highly valued ethnomedicinal plant, has been traditionally used to treat various ailments due to its rich phytochemical composition. However, the impact of environmental factors, particularly altitude, on its medicinal properties remains unexplored. This study investigates the effects of altitudinal variation on phytochemicals, mycorrhizal diversity, and soil physico-chemical parameters of R. indica. RESULTS: The phytochemical study of R. indica revealed significant variations in phytochemical content across different altitudes. The methanol extract from the high-altitude site (i.e. Chail, 2000 m) exhibited the highest levels of phenol (142.63 ± 1.88 mg/g GAE), tannins (146.11 ± 1.73 mg/g GAE), flavonoid (51.59 ± 2.20 mg/g RUT), carbohydrate content (485.00 ± 1.52 mg/g GLU), and protein (12.95 ± 0.35 mg/g GAE). GC-MS analysis identified different bioactive compounds with antioxidant, antimicrobial, and antitumor properties. HPLC analysis showed varying rutin content across altitudes, with the highest amount at higher altitude. The plant's association with arbuscular mycorrhizal fungi decreased with increasing altitude, as evidenced by reduced mycorrhizal spore diversity and root colonization. Soil physico-chemical properties like soil pH, organic carbon, phosphorus and nitrogen also increased with the altitude. CONCLUSION: This study demonstrates that altitudinal variation significantly influences the phytochemical composition, mycorrhizal diversity, and soil properties of R. indica. High-altitude sites exhibited increased phytochemical content, particularly phenols, flavonoids, and tannins, suggesting enhanced medicinal value. Conversely, mycorrhizal association decreased with altitude, potentially due to environmental and soil property changes. These findings have implications for optimizing cultivation and conservation strategies for R. indica, highlighting the importance of altitude considerations in harnessing its medicinal potential.

The prevalence of chronic venous disease (CVD) is relatively high, it affects 20-80 % of the population worldwide. CVD may affect any veins in the human body, however, the veins of the lower extremities are the most susceptible to this condition. Among therapeutic possibilities for CVD, mainly chronic venous insufficiency, some medicinal plants (Ruscus aculeatus L., Aesculus hippocastanum L., Centella asiatica (L.) Urb.) and their active compounds (ruscoside, aescin, asiaticoside) or close derivatives also have important places. This review describes shortly the updated knowledge on pathophysiology, clinical manifestations, evaluation, and diagnostics of CVD as well as treatment modalities. The primary focus of this review is on the existing knowledge about botanical medications for treating chronic venous disease (CVD). It covers the chemical makeup of these plant drugs, their pharmacological effects, results from clinical trials involving humans, and any associated safety concerns.

Several Ranunculaceae species are used in folk medicine to eliminate pathologies associated with oxidative stress as well as parasitic infections; however, a number of studies confirming their pharmacological properties is limited. In this study, 19 ethanolic extracts obtained from 16 Ranunculaceae species were assayed for in vitro antioxidant, antiproliferative, and antiparasitic potential. The maximum antioxidant potential in both oxygen radical absorbance capacity (ORAC) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assays was observed for Aconitum toxicum extract [half-maximal inhibitory concentration (IC50) 18.7 and 92.6 μg/mL]. Likewise, Anemone transsilvanica extract exerted the most promising antiproliferative activity against Caco-2 (IC50 46.9 μg/mL) and HT29 (IC50 70.2 μg/mL) cell lines in 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Additionally, a dual antioxidant and cytotoxicity effect was demonstrated for Aconitum moldavicum and Caltha palustris extracts. Whilst the efficacy of extracts was modest against Trypanosoma brucei (IC50 ranging from 88.8 to 269.3 µg/mL), several extracts exhibited high potency against Leishmania infantum promastigotes (Aconitum vulparia IC50 18.8 µg/mL). We also tested them against the clinically relevant intracellular stage and found extract of A. vulparia to be the most effective (IC50 29.0 ± 1.1 µg/mL). All tested extracts showed no or low toxicity against FHs 74Int normal cell line (IC50 ranging from 152.9 to >512 µg/mL). In conclusion, we suggest the above-mentioned plant extracts as potential candidates for development of novel plant-based antioxidant and/or antiproliferative and/or antileishmanial compounds.

Indigenous knowledge of medicinal plants is vital to local communities and cultural heritage, particularly in Ethiopia. This study aims to document native medicinal plants in the Jawi district, including associated traditional knowledge. The study involved conducting semi-structured interviews, focus group discussions, and guided field walks with a purposefully selected 54 traditional healers. The study identified 87 medicinal plant species from 50 families used treat over 50 ailments, with a preference for wild herbs. Fabaceae, Malvaceae, and Solanaceae were the most prominent families, each with five species; Zehneria scabra, was the most often mentioned species, followed by Lepidium sativum, Myrica salicifolia, Carissa spinarum, and Momordica foetida. 43% of identified species were herbs, with 44% of remedies made from roots. Pounding was the most common preparation method, and oral application was the most frequent use, followed by dermal application. 60% plants treated human ailments, 16% treated livestock, and 24% were used for both. Preference rankings indicated specific plants favored for certain ailments. The study highlights key plant families and species crucial for local healthcare but notes threats like habitat destruction and knowledge loss. Urgent conservation actions are needed to preserve medicinal plants and inform future research and strategies.

Despite their overlooked status, weeds are increasingly recognized for their therapeutic value, aligning with historical reliance on plants for medicine and nutrition. This study investigates the medicinal potential of native weed species in Bangladesh, specifically pigments, antioxidants, and free radical scavenging abilities. Twenty different medicinal weed species were collected from the vicinity of Khulna Agricultural University and processed in the Crop Botany Department Laboratory. Pigment levels were determined using spectrophotometer analysis, and phenolics, flavonoids, and DPPH were quantified accordingly. Chlorophyll levels in leaves ranged from 216.70 ± 9.41 to 371.14 ± 28.67 µg g-1 FW, and in stems from 51.98 ± 3.21 to 315.89 ± 17.19 µg g-1 FW. Flavonoid content also varied widely, from 1,624.62 ± 102.03 to 410.00 ± 115.58 mg CE 100 g-1 FW in leaves, and from 653.08 ± 32.42 to 80.00 ± 18.86 mg CE 100 g-1 FW in stems. In case of phenolics content Euphorbia hirta L. displaying the highest total phenolic content in leaves (1,722.33 ± 417.89 mg GAE 100 g-1 FW) and Ruellia tuberosa L. in stems (977.70 ± 145.58 mg GAE 100 g-1 FW). The lowest DPPH 2.505 ± 1.028 mg mL-1was found in Heliotropium indicum L. leaves. Hierarchical clustering links species with pigment, phenolic/flavonoid content, and antioxidant activity. PCA, involving 20 species and seven traits, explained 70.07% variability, with significant PC1 (14.82%) and PC2 (55.25%). Leaves were shown to be superior, and high-performing plants such as E. hirta and H. indicum stood out for their chemical composition and antioxidant activity. Thus, this research emphasizes the value of efficient selection while concentrating on the therapeutic potential of native weed species.

Wild chimpanzees consume a variety of plants to meet their dietary needs and maintain wellbeing. While some plants have obvious value, others are nutritionally poor and/or contain bioactive toxins which make ingestion costly. In some cases, these nutrient-poor resources are speculated to be medicinal, thought to help individuals combat illness. In this study, we observed two habituated chimpanzee communities living in the Budongo Forest, Uganda, and collected 17 botanical samples associated with putative self-medication behaviors (e.g., bark feeding, dead wood eating, and pith-stripping) or events (e.g., when consumer had elevated parasite load, abnormal urinalysis, or injury). In total, we selected plant parts from 13 species (nine trees and four herbaceous plants). Three extracts of different polarities were produced from each sample using n-hexane, ethyl acetate, and methanol/water (9/1, v/v) and introduced to antibacterial and anti-inflammatory in vitro models. Extracts were evaluated for growth inhibition against a panel of multidrug-resistant clinical isolates of bacteria, including ESKAPE strains and cyclooxygenase-2 (COX-2) inhibition activity. Pharmacological results suggest that Budongo chimpanzees consume several species with potent medicinal properties. In the antibacterial library screen, 45 out of 53 extracts (88%) exhibited ≥40% inhibition at a concentration of 256 μg/mL. Of these active extracts, 41 (91%) showed activity at ≤256μg/mL in subsequent dose-response antibacterial experiments. The strongest antibacterial activity was achieved by the n-hexane extract of Alstonia boonei dead wood against Staphylococcus aureus (IC50: 16 μg/mL; MIC: 32 μg/mL) and Enterococcus faecium (IC50: 16 μg/mL; MIC: >256 μg/mL) and by the methanol-water extract of Khaya anthotheca bark and resin against E. faecium (IC50: 16 μg/mL; MIC: 32 μg/mL) and pathogenic Escherichia coli (IC50: 16 μg/mL; MIC: 256 μg/mL). We observed ingestion of both these species by highly parasitized individuals. K. anthotheca bark and resin were also targeted by individuals with indicators of infection and injuries. All plant species negatively affected growth of E. coli. In the anti-inflammatory COX-2 inhibition library screen, 17 out of 51 tested extracts (33%) showed ≥50% COX-2 inhibition at a concentration of 5 μg/mL. Several extracts also exhibited anti-inflammatory effects in COX-2 dose-response experiments. The K. anthotheca bark and resin methanol-water extract showed the most potent effects (IC50: 0.55 μg/mL), followed by the fern Christella parasitica methanol-water extract (IC50: 0.81 μg/mL). This fern species was consumed by an injured individual, a feeding behavior documented only once before in this population. These results, integrated with associated observations from eight months of behavioral data, provide further evidence for the presence of self-medicative resources in wild chimpanzee diets. This study addresses the challenge of distinguishing preventative medicinal food consumption from therapeutic self-medication by integrating pharmacological, observational, and health monitoring data-an essential interdisciplinary approach for advancing the field of zoopharmacognosy.

BACKGROUND: The use of medicinal plants is integral to global healthcare systems, with Sub-Saharan Africa maintaining a robust tradition of herbal medicine alongside Western-oriented healthcare. As migrant communities tend to continue traditional herbal practices after migration, documenting this use is vital to develop culturally sensitive healthcare. This study investigates plant usage and perspectives in the context of sexual and reproductive health among the Congolese community in Belgium, particularly in the Matongé quarter of Brussels. Our research questions were: (1) What is the current knowledge of medicinal plants among the Congolese community in Belgium in the context of sexual health, and what are the applications and commonly employed administration methods of these plants? (2) What role does herbal medicine play in the context of sexual health for people of Congolese descent in Belgium and how this is influenced by perceptions of sexuality? and (3) Is there a gender bias in the use of medicinal plants, and if so, can this be related to perceived gender norms? METHODS: We conducted 22 semi-structured interviews with people of Congolese descent currently living in Belgium. Participants were selected using both snowball sampling and purposive sampling. Plant use in the context of sexual health was recorded through freelisting. Data on narratives, ideas, and perceptions of this plant use in the context of sexual health were collected. Interview transcripts were analyzed using thematic analysis. RESULTS: We identified 17 plant species used for sexual health. Three overarching themes emerged from our data. Plants were used with a notable gender bias favoring male sexual potency enhancement. Men used these plants for both remedying potency issues and enhancing sexual prowess. In contrast, knowledge about plants for female sexual health was limited. Gender norms reinforced the importance of male sexual potency, while stigmatizing open discussions of female sexuality. CONCLUSIONS: The use of medicinal plants for sexual health raises health, social, and conservation concerns, underscoring the need for further research in this area. This study contributes to understanding medicinal plant use within the Congolese community in Belgium and highlights the necessity for future research on herbal practices for female sexual health in this context.

From the leaves and stem bark of the Kenyan medicinal plant Calpurnia aurea subsp. aurea, four previously undescribed quinolizidine alkaloids namely, 2β-methoxy-13α-O-(2'-pyrrolylcarbonyl) virgiline, 2α-methoxy-13β-O-(2'-pyrrolylcarbonyl) virgiline, 3α-O-angelate-2β-hydroxy-13α-O-(2'-pyrrolylcarbonyl) virgiline, 2,3-dehydro-virgiline were isolated together with four known ones. Structural elucidation of the compounds was based on 1D and 2D NMR spectroscopy and mass spectrometry. Their relative configurations were determined by NOESY correlations and literature. The quinolizidine alkaloids were tested against Trichophyton rubrum, Trichophyton interdigitale, Trichophyton benhamiae, Microsporum canis and Nannizzia gypsea, common causative agents of most of the tinea infections in human. All the isolated quinolizidine alkaloids exhibited antidermatophytic activity with MIC ranging from 37.5 μg/ml to 300 μg/ml.

Unlike conventional drug substances, herbal medicines are composed of a complex of biologically active compounds. Therefore, the potential occurrence of herb-drug interactions is even more probable than for drug-drug interactions. Interactions can occur on both the pharmacokinetic and pharmacodynamic level. Herbal medicines may affect the resulting efficacy of the concomitantly used (synthetic) drugs, mainly on the pharmacokinetic level, by changing their absorption, distribution, metabolism, and excretion. Studies on the pharmacodynamic interactions of herbal medicines and conventional drugs are still very limited. This interaction level is related to the mechanism of action of different plant constituents. Herb-drug interactions can cause changes in drug levels and activities and lead to therapeutic failure and/or side effects (sometimes toxicities, even fatal). This review aims to provide a summary of recent information on the potential drug interactions involving commonly used herbal medicines that affect the central nervous system (Camellia, Valeriana, Ginkgo, Hypericum, Humulus, Cannabis) and conventional drugs. The survey databases were used to identify primary scientific publications, case reports, and secondary databases on interactions were used later on as well. Search keywords were based on plant names (botanical genera), officinal herbal drugs, herbal drug preparations, herbal drug extracts.
