Introduction: Thai Traditional herbal medicine employs multi-herb formulations for managing inflammatory conditions. This study investigates the anti-inflammatory properties, cytotoxicity, and chemical composition of Cha-Nu-Ruk, an eight-herb traditional poultice formulation for knee pain. Methods: Eight medicinal plants (Tiliacora triandra, Thunbergia laurifolia, Azadirachta indica, Clinacanthus nutans, Pandanus amaryllifolius, Justicia gendarussa, Sida acuta, and Zingiber cassumunar) were extracted with 70\% ethanol. Anti-inflammatory activity was evaluated through nitric oxide inhibition assay using Jurkat cells. Cytotoxicity was assessed via MTT assay. Chemical profiling employed GC-MS analysis. Results: Individual plant extracts demonstrated variable anti-inflammatory activity (NO inhibition: 28.52-73.80\%) with Clinacanthus nutans showing highest potency. The combined eight-herb formulation yielded 11.82{\textpm}0.41\% extraction efficiency with 26.2\% NO inhibition. GC-MS analysis identified 21 compounds, with DMPBD (19.13\% relative abundance) and β-sitosterol (1.13\%). Cytotoxicity evaluation revealed acceptable safety profiles (\>80\% cell viability) for most extracts. Conclusions: While individual herbs showed promising anti-inflammatory potential, the traditional eight-herb combination did not demonstrate synergistic enhancement. Chemical standardization revealed significant batch-to-batch variability, highlighting the need for optimized formulation ratios and quality control protocols.

Introduction: The rhizome of Enhalus acoroides (L.f.) Royle is used in traditional medicine for treatment of many diseases e.g. muscle pains, wounds and stomach problems where pharmacognostical studies are lacking. Many chemical constituents; luteolin, apigenin, luteolin glycosides, stigmasterol, daucosterol have been reported. The aim of this work was to perform a pharmacognostical evaluation. Methods: Macroscopical, microscopical and physicochemical parameters were assessed. Results: E. acoroides has characteristic morphology. Microscopical studies indicated the presence of vessels, fiber, parenchyma cells, sclereids, tracheids and trichomes. Physicochemical parameters of E. acoroides rhizome; foreign matter, loss on drying and total ash content were measured. As well as chemical investigation through TLC and HPLC were specified. Conclusion: The present study of E. acoroides rhizome provides useful information that can serve as a diagnostic tool for the standardization of E. acoroides and will be helpful in characterization of the crude drug in the market.
