Carrot Seed (Davcus Carota Sativa) This must be one of the most underrated essential oils in aromatherapy. It has a soft earthy smell and not only helps to relieve stress and exhaustion, but is a powerful detoxifier and liver booster, while stimulating and rejuvenating the skin in general, thereby adding elasticity to any skin. At the same time it fights any skin problems, such as psoriasis, eczema, weeping sores, ulcers, boils and carbuncles. The formative action on the epidermal cells help to keep wrinkles at bay and is also helpful when fighting liver spots (age spots).
