The Green and Red are used in much the same way. The Red having a sweeter and riper scent. Also known as Tangerine or Satsuma. Mandarin is the only citrus that is sedating. This is great added to the diffusor to calm and relax with especially when the tension is nervous. This can be added to facial products to increase skin tone and to reduce congested and acne prone skin. Can soften scars and seriously dry patches.New shipment from a distillery in France this Fall. Very bright and yummy.
