    ETHNOPHARMACOLOGICAL RELEVANCE: Derris scandens (Roxb.) Benth. has been used as active ingredient in Thai traditional medicine recipes for pain treatment. Dry stem powder and ethanolic extract also recommended in Thailand National List of Essential Medicines (NLEMs) for musculoskeletal pain treatment as herbal medicine. However, no summarization of clinical effect and safety has been evaluated.

    OBJECTIVE: Our study aimed to determine the clinical effects and safety of D. scandens for musculoskeletal pain treatment compared with standard regimen, nonsteroidal anti-inflammatory drugs (NSAIDs).

    METHODS: International and Thai databases were searched from inception through August 2015. Comparative randomized controlled trials investigating oral D. scandens for musculoskeletal pain were included. Outcomes of interest included level of pain and adverse event. Mean changes of the outcomes from baseline were compared between D. scandens and NSAIDs by calculating mean difference.

    RESULTS: From 42 articles identified, 4 studies involving a total of 414 patients were included for efficacy analysis. The effects of oral D. scandens on reducing pain score were no different from those of non-steroidal anti-inflammatory drugs at any time points (3, 7, 14 days and overall). The overall pain reduction in the D. scandens group was not inferior to treatment with NSAIDs (weighted mean difference 0.06; 95% CI: -0.20, 0.31) without evident of heterogeneity (I(2)=0.00%, p=0.768). When compared, the adverse events (AEs) of D. scandens showed no different relative risk with NSAIDs. The major adverse events were gastrointestinal symptoms.

    CONCLUSION: D. scandens may be considered as an alternative for musculoskeletal pain reduction.

    Trypanosoma evansi, the causative agent of "surra", infects many species of wild and domestic animals worldwide. In the current study, the aqueous and ethanolic extracts of six medicinal plants, namely, Aquilaria malaccensis, Derris elliptica, Garcinia hombroniana, Goniothalamus umbrosus, Nigella sativa, and Strobilanthes crispus were screened in vitro for activity against T. evansi. The cytotoxic activity of the extracts was evaluated on green monkey kidney (Vero) cells using MTT-cell proliferation assay. The median inhibitory concentrations (IC50) of the extracts ranged between 2.30 and 800.97 μg/ml and the median cytotoxic concentrations (CC50) ranged between 29.10 μg/ml and 14.53 mg/ml. The aqueous extract of G. hombroniana exhibited the highest selectivity index (SI) value of 616.36, followed by A. malaccensis aqueous extract (47.38). Phytochemical screening of the G. hombroniana aqueous extract revealed the presence of flavonoids, phenols, tannins, and saponins. It is demonstrated here that the aqueous extract of G. hombroniana has potential antitrypanosomal activity with a high SI, and may be considered as a potential source for the development of new antitrypanosomal compounds.
