In their seminal reference book, Prescription for Nutritional Healing, Dr. James Balch and the late Phyllis Balck, C.N.C., outlined several such oils.
Emu Oil - An excellent source of linoleic acid, linolenic acid, and oleic
acids, all of which have anti-inflammatory properties. It can be used topically for a number of
problems, including skin bites and poison ivy.
Fish Oil - This is a good source of omega-3s, with salmon, makcere, menhanden, herring, and sardines favored because they have a higher fat content.
Flaxseed Oil - Rich in essential fatty acids, several studies have shown it can reducce pain, inflammation, and arthritis. Dr. Balch and Ms. Balch also wrote that it has helped lower blood cholesterol and helped reduce the hardening effects of cholesterol on cell membranes.
Flaxseed also has tremendous benefits and is a terrific addition to shakes, salads, and yogurt.
Grape Seed Oil - Like flaxseed, it's ideal for cooking. It can be heated at temperatures up to 485 degrees F and has a "light, nutty taste that brings out the flavors in many foods," Dr. Balch and Ms. Balch wrote. Also, it has no cholesterol, no sodium, and it has among the lowest amount of saturated fats among the EFAs.
Primrose Oil - It contains 9 to 10 percent gamma linolenic acid, a beneficial omega-6. It's been known to "help prevent hardening of the arteries, heart disease, premenstrual syndrome, multiple sclerosis, and high blood pressure."
Also, "it relieves pain and relieves inflammation; enhances estrogen and testosterone; aids in lowering cholesterol levels; and is beneficial for cirrhosis of the liver," according to Dr. Balch and Ms. Balch.
