Cypress oilwas analyzed using GC-MS,revealingα-pinene (50.72%) and 3-β-carene (27.57%) asthe major constituents.An optimized nanoemulsion (dropletsize 105.28±2.12 nm, PDI 0.112±0.016) wasincorporated into a carbopol hydrogelto form a stable nanoemulgelwith a zeta potential of –33 mV. The nanoemulgel exhibited enhanced antioxidant activity,with an IC50 of 6.6±0.13 μg ml−1 , compared to 14.7±0.3 μg ml−1 forthe oil alone.It demonstrated potent antimicrobial activity against multiple bacterialstrains,with inhibition zones of 11–36 mm, and antifungal activity againstCandida albicans (16–24 mm). Strong anticancer effectswere observed againstHep-G2 (IC 50 39.81 μg ml−1 ),MCF-7 (IC 50 58.88 μg ml−1 ), andHeLa (IC 50 61.65 μg ml−1 ) cells, alongwith anti-fibrotic activity on LX-2 cells(IC 50 63.09 μg ml−1 ). SelectiveCOX-2 inhibitionwas also confirmed (IC50 13.96 μg ml−1 ).These findings highlightthat cypress oil-loaded nanoemulgel effectively enhancesthe biological activities of cypress oil,suggesting its potential as a therapeutic platform for managing infections, inflammation, and cancer
