Lavandula x intermedia 'Grosso' is the dominant commercial lavandin cultivar — accounting for an estimated 75% of global lavandin production — and yields an essential oil with linalool (27-33%) and linalyl acetate (31-38%) as principal components, accompanied by comparatively modest camphor (6.5-7.7%) and 1,8-cineole (4.5-6.6%).^[1] Cell-based assays show that 'Grosso' oil at 0.0001% upregulates the antioxidant-response genes NQO1 and CYTB in SH-SY5Y neuronal cells, a profile distinguishable from both 'Abrialis' and L. angustifolia oils tested under identical conditions.^[1]
