“…Medicinal plants, in turn, are indispensable for maintaining the health and safety of people in different parts of the world. Currently, in many South American countries, approximately 80% of the population uses medicinal plants (Firmo et al 2011), revealing a high degree of dependence (Nunes and Albuquerque, 2018). The number of studies on medicinal plants has increased significantly worldwide since the 1990s (Nunes and Albuquerque 2018).…”

“…Currently, in many South American countries, approximately 80% of the population uses medicinal plants (Firmo et al 2011), revealing a high degree of dependence (Nunes and Albuquerque, 2018). The number of studies on medicinal plants has increased significantly worldwide since the 1990s (Nunes and Albuquerque 2018). Since climate change may affect species distribution and physiology (e.g., Scheffers et al 2016), it may become an important threat to medicinal plant species and their ecosystem services (Borges et al 2017a;Gupta et al 2019).…”

Disruption of ecosystem services associated with climate change may affect human well-being in different ways. Medicinal plants provide extremely relevant ecosystem services. Here, we tested the hypothesis that highly suitable habitats (i.e., suitability ≥ 0.8) for medicinal plants in Caatinga dry forest may be potentially contracted under scenarios of climate change, which are represented by different levels of increases in greenhouse gas emissions. We performed species distribution modelling to simulate the effects of climate change on the range of suitable habitats for medicinal plants native to the Caatinga dry forest. We selected the 10 most important plant species based on their high local importance as medicinal resources. We documented that climate change may distinctly affect areas of suitable habitats for medicinal plants in the Caatinga dry forest. Independent of the future climatic scenario projected to 2090, 70% of the studied species will likely experience reductions in their areas of highly suitable habitats and 30% will likely experience increases. Specifically, suitable habitats will likely be reduced for (1) Amburana cearensis, (2) Anadenanthera colubrina, (3) Bauhinia cheilantha, (4) Myracrodruon urundeuva, (5) Neocalyptrocalyx longifolium, (6) Operculina hamiltonii, (7) O. macrocarpa; and will likely be increased for (1) Cereus jamacaru, (2) Erythrina velutina, (3) Maytenus rigida. We also documented a reduction in medicinal plant species richness and composition in all three future climatic scenarios analyzed. We alert that potential future contractions of highly suitable habitats for the most important medicinal plants may compromise ecosystem functions and the provisioning of relevant natural medicines, mainly to low-income communities, which are abundant in the Caatinga dry forest.

“…The tropical forests of Colombia boast remarkable biodiversity of flora and fauna, thanks to their abundant rainfall, which is the highest among all the regions in the Americas. This climatic condition, characterized by a bimodal regime, directly supports diverse ecosystems and promotes biodiversity [ 7 ]. Unfortunately, these once-pristine ecosystems have faced increasing devastation over the past five decades due to human activities, particularly poor agricultural practices such as extensive livestock farming and monocultures.…”

The utilization of plants with medicinal properties is deeply rooted in the traditional knowledge of diverse human populations. This study aims to investigate the cytotoxicity of nine plants commonly used by communities in San Basilio de Palenque, Bolivar (Colombia), for managing inflammation-related illnesses. Hydroethanolic extracts from various plant parts such as roots, stems, barks, or leaves were prepared through a process involving drying, powdering, and maceration in an ethanol–water (7:3) solution. The extracts were subsequently freeze-dried and dissolved in DMSO for the bioassays. Cytotoxicity against the human hepatoma HepG2 cell line was assessed using the MTT assay, with extract concentrations ranging from 0 to 500 µg/mL and treatment durations of 24 and 48 h. The total phenolic content of the nine extracts varied from 96.7 to 167.6 mg GAE/g DT. Among them, eight hydroethanolic extracts from Jatropha gossypiifolia L., Piper peltatum L., Malachra alceifolia, Verbesina turbacensis, Ricinus communis, Desmodium incanum, and Dolichandra unguis-cati showed low toxicity (IC50 > 500 µg/mL, 24 h) against HepG2 cells. On the other hand, the extracts of Aristolochia odoratissima L. (IC50 = 95.7 µg/mL) and Picramnia latifolia (IC50 = 128.9 µg/mL) demonstrated the highest cytotoxicity against the HepG2 cell line, displaying a modest selectivity index when compared to the HEKn cell line after 48 h of treatment. These findings suggest that medicinal plants from San Basilio de Palenque, particularly Picramnia latifolia and Aristolochia odoratissima, have potential activity against cancer cells, highlighting their potential for further research and development.
