Citrus hystrix has a sharp, fresh citrusy aroma.  It is produced on-site at the Essential Essence Aromatherapy Oils distillery using locally obtained fruit peel.  This oil will not cause phototoxic skin irritation because it is steam distilled.  You can use lime oil for headaches, oily skin, stress related disorders and acne.  It blends well with other citrus essences, clary sage, lavender, rosemary and ylang Ylang
