Citrus reticulata also known as Citrus deliciosa
Tangerine and Mandarin are the same oil -- although the fruit from the tree are slightly different in color -- the essential oil is the same.
It protects wounds from becoming septic as well as from other bacterial, fungal or viral infections. It forms a protective covering on the wound and promotes the collection of blood platelets and leucocytes at the affected place, thereby blocking the intrusion of microbes. Furthermore, the oil itself has bactericidal and fungicidal properties and kills them, thereby adding to this protective effect.
It is also known to be helpful with spasm in both the respiratory system and the digestive system, to name a few.
As always, with all citrus oils, be mindful of their skin sensitizing action -- always use in a carrier, and never with direct sun.
