Conservation status of species used in the UK herbal medicine industry

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1692-1701, September 2026.
Given the ongoing biodiversity crisis, sustainable use and management of medicinal plants is critical. We assessed the conservation status, threats and conservation actions of 298 species sold by UK suppliers to medical herbalists. We found that most species used are unevaluated, representing a gap in conservation knowledge, and of those with ...

17‐epi‐Melianodiol, a new protolimonoid from Melia azedarach fruits, exhibits larvicidal activity and is associated with oxidative imbalance and midgut epithelial damage in Aedes aegypti larvae

Pest Management Science, Volume 82, Issue 9, Page 9240-9248, September 2026.
The bio‐guided phytochemical study resulted in the new compound 17‐epi‐melianodiol. The compound eliminated 100% of Aedes aegypti larvae at 100 ppm, causing pronounced morphological changes, cuticular damage, and extensive vacuolization. Abstract BACKGROUND In Brazil, Aedes aegypti is the primary vector of arboviruses such as dengue, chikungunya ...
