Avocado carrier oil is a penetrating oil, and invaluable when added to massage preparations to help circulationcellulite and fluid retention. It is rich in lecithin and vitamins A, B and D. Avocado carrier oil is a yellow to green slightly cloudy oil which can congeal slightly when cold, but will then liquefy at room temperature, these traits are considered to be a good sign as it means the oil has not been extensively refined. 

The tree originates from the tropical and sub-tropical Americas where it was discovered by the Spanish in the 15th century. Avocados have been cultivated for over 7000 years though were little known outside the Americas until the 20th century.
