Frankincense essential oil is known for its immunostimulant and expectorant properties. It strengthens the natural defenses and acts on respiratory disorders. Its fragrance induces relaxation and meditation and calms states of agitation. Frankincense comes from a small tree in the arid regions of Africa or Arabia. It is obtained by steam distillation of aromatic plants, i.e. flower, leaf, wood, root, bark and fruit.
