Petitgrain is one of three oils derived from the Bitter Orange tree, which also gives us Bitter Orange (from the rind of the fruit) and Neroli (from the flowers). Formerly derived from the unripe fruits (hence the name petit grain) it is now more cost-effectively produced from the leaves. The oil is a great balancing oil, a component of many fragrances, and has wide value in aromatherapy with its uplifting influence, which makes it useful for against the blues, as an aid to sleep and for stress and anxiety. Petitgrain is produced from a number of different citrus trees. It blends well with Lavender, Clary Sage, Geranium, and Sandalwood.
