The most useful of the four gift packs, because both bottles get used long after the occasion.

Tranquil Sleep is bergamot, lavender, neroli and clary sage, the blend Dolphin Clinic recommend for a bedroom vaporiser and specifically for children who have got over-excited before bed. The lavender is French Lavandula angustifolia, the single most versatile oil in the range and one of the few that can go straight on skin.

Diffuse the blend, or put three to six drops on a tissue by the pillow. Dab two to four drops of lavender on wrists, or add it to a bath.

Avoid if pregnant.
