In Traditional Chinese Medicine (TCM), mugwort (Artemisia vulgaris) is documented as the primary material for moxibustion, prepared as moxa floss (ai rong, 艾绒), moxa cones (ai zhu, 艾炷), and moxa sticks (ai tiao, 艾条) to warm the channels and regulate qi–blood [6–8]. We therefore investigated A. vulgaris compounds for multi-target anti-gout relevance, anchored in these TCM indications.
Network pharmacology and molecular docking prioritized A. vulgaris phytochemicals against gout-related targets, followed by in-vitro validation in LPS-challenged RAW 264.7 macrophages.
Of 62 compounds, 52 met drug-likeness and intersected 277 gout genes. A flavonoid (AV52) showed strong predicted binding to PTGS2/XO, and artemisinin (AV46) to urate transporters (SLC22A12/ABCG2). Experimentally, AV46 reduced IL-6/TNF-α and nitrite while preserving IL-10. IL-10 showed a small, non-monotonic change at 6.25 µM (p < 0.05) that was not reproduced at adjacent doses, suggesting limited biological relevance, while overall IL-10 was preserved alongside reductions in IL-6 and TNF-α.
Framed within TCM practice of moxibustion and warming/qi–blood-regulating indications, these data support a lead–anchor concept (AV52 anti-inflammatory/XO; AV46 uricosuric-anti-inflammatory) warranting further in-vivo and formulation studies for TCM-relevant applications.
A. vulgaris phytochemicals demonstrate complementary potential against gout-related inflammation and urate handling within a TCM use-case anchored to mugwort preparations (moxa floss/cones/sticks). AV46 showed experimental activity consistent with predictions, while AV52 requires bench confirmation. These results motivate focused biochemical, transporter, pharmacokinetic, and in-vivo evaluations to support translation into Chinese preparation - compatible applications.
