The Blood Orange is a variety of sweet orange, also known as Citrus sinensis. The name Blood Orange indicates its blood-red coloured pulp inside the fruit. Blood orange essential oil is derived from the peel of blood oranges, a type of orange with a deep red or crimson flesh. The chemical constituents in the fruit’s essential oil are antiseptic and healing in nature, and its red pigment, anthocyanin, is an antioxidant that is rare to find in the fruits of the rest of the citrus family.  The oil has a sweet, citrusy aroma with a hint of bitterness, and is often used in aromatherapy to promote relaxation and reduce stress and anxiety.
