A simple but genuinely useful bit of kit for anyone who mixes their own aromatherapy blends. This calibrated 50ml glass bottle from Tisserand takes the guesswork out of home blending, letting you measure carrier oil accurately and add essential oils drop by drop.

The bottle is made from glass with a secure cap, and volume markings on the side help you follow standard dilution guidance easily: five drops of essential oil per 10ml of carrier oil for massage, up to two drops per 10ml for facial use, or four to six drops in 20ml for a bath blend. Once your mix is in, cap the bottle and shake well. Label anything you make, store it away from heat and light, and keep all blends out of reach of children. A handy companion to any of the Tisserand carrier oils.
