Ethnopharmacology and Natural Products in Drug Discovery

Ethnopharmacology integrates anthropological insights into traditional medical practices with modern biochemical and pharmacological methods to identify and validate bioactive compounds from natural sources. Drawing on centuries of empirical knowledge, researchers investigate plants, fungi, marine organisms and microbial symbionts for structurally diverse metabolites that can serve as drug leads. Advances in analytical chemistry, high-resolution spectroscopy and metabolomic profiling have accelerated the isolation and characterisation of secondary metabolites, while computational approaches such as molecular docking and network pharmacology enable in silico prioritisation of candidates. Emphasis on polypharmacology acknowledges that many natural extracts exert therapeutic effects through synergistic interactions across multiple targets. Sustainable sourcing and conservation of biodiversity are increasingly recognised as essential components of the discovery pipeline, prompting collaborations between ethnobotanists, chemists, pharmacologists and data scientists to preserve both biological and cultural heritage. This interdisciplinary framework addresses global health challenges—ranging from antimicrobial resistance to chronic diseases—by harnessing the chemical ingenuity of nature and the depth of traditional knowledge.

Research from Nature Portfolio

One foundational study applied a phylogeny-guided framework to the genus Euphorbia, reinterpreting traditional medicinal uses according to biological response categories rather than conventional body-system classifications. By mapping uses related to the inflammatory response onto an evolutionary tree, researchers identified clades with unexpectedly high chemical diversity and a greater number of promising species for early-stage screening. This approach demonstrated that integrating evolutionary history into ethnopharmacological assessments can substantially improve the efficiency of lead discovery and uncover novel structural scaffolds.

Technical terms

Ethnopharmacology: interdisciplinary field studying traditional medicinal practices and the bioactive natural substances employed within cultural contexts.

Phylogenetic screening: approach using evolutionary relationships to predict the distribution of bioactive compounds and guide selection of species for study.

Dereplication: rapid analytical identification of known metabolites in complex extracts to prevent redundant isolation of previously characterised compounds.

Metabolomic profiling: comprehensive analysis of small-molecule metabolites in biological samples to characterise chemical diversity and potential biological effects.

Polypharmacology: design and investigation of compounds that act on multiple molecular targets, reflecting the multifaceted nature of many diseases and traditional medicinal extracts.
