Hydrodistilled essential oil of the aerial parts of Laggera crispata (Vahl) Hepper & Wood, collected from the Kumaon region of the western Himalayas was analysed by gas chromatography and gas chromatography-mass spectrometry. Eighty constituents, accounting for 83.9 % of the total oil composition, were identified. The oil was mainly dominated by sesquiterpenoids (45.3 %) and benzenoid compounds (33.9 %). Among them, 2,5-dimethoxy-p--cymene (32.2 %), 10-epi-γ-eudesmol (14.7 %), β-caryophyllene
