In addition to the above oils that stimulate and decongest the lymphatic system, there are a few oils that have been proven effective in stimulating the production of white blood cells: LAVENDER, BERGAMOT, LEMON, NIAOULI, ROSEMARY, TEA TREE and RAVINTSARA.
A 1995 Mie University study found that citrus fragrances boosted immunity, induced relaxation, and reduced depression. LEMON essential oil is an immune stimulant. It increases white blood cells, improves microcirculation and is antiseptic. Lemon essential oil consists of 68 percent d-limonene, a powerful antioxidant. Lemon has an approximate ORAC (Oxygen Radical Absorption Capacity) of 6,619 (TE/L). TE/L is expressed as micromole Trolox equivalent per liter. D-limonene has been extensively studied for its ability to combat tumor growth in over 50 clinical studies.
