Seed research in Minnesota
Posted on June 30, 2014 by Bradford S. Weeks, MD
Dr. Weeks’ Comment: Dr. Leonard and U. Minnesota have pioneered the research in the USA re black cumin seed oils as well as black raspberry seed oils and Chardonnay grape seed oils. These are the key ingredients in SOUL – a powerful anti-inflammatory and anti-oxidant drink which also is loaded with concentrated nutrients!
Creation of Super-Potent Antioxidant Values Through Synergy of Cold-Pressed Botanic Oils for Therapeutic Purposes
By Arnold S. Leonard, MD, PhD; Dan Saltzman, MD, PhD; and Mark Mueller
Free radicals are atoms or molecules with open negative charges capable of damaging the human body. Free radicals are produced as a result of metabolism, by dietary imbalances or pollutants, or from inflammation and biochemical reactions in the body, that can increase the probability of viral infections or cancer.
Long-term presence of these oxidizing radicals eventually can be detrimental to the human body. Oxidative stress also is thought to play an important role in numerous chronic diseases, such as coronary heart disease and cancer. Although there are many factors in the development of these diseases, considerable experimental evidence has linked the production of free radicals to biologic damage that can provide a basis for the beginning, as well as the progression, of certain diseases. When free radicals exceed the body’s capacity to protect or repair itself, oxidative damage can occur. Penetration of the cell membrane over time leads to oxidative damage to organelles.
Antioxidants, which reduce oxidative stress, might play a role in the prevention or treatment of many diseases, and also might slow the progression of aging. The accumulation and growth of free radicals in the body often occur in association with a suppressed immune system, including infections such as HIV, SARS, cancer and heart disease. Diets high in added antioxidants have been shown experimentally to be protective against cancer and various diseases. Damage to the heart also has been shown experimentally to be reduced with increased dietary antioxidant intake.
Cold-pressed plant seed oils that can be extracted from seeds and other parts of various plants have been found to be excellent sources of antioxidants. In addition to traditional antioxidants such as vitamins C and E, plant oils contain phenolic compounds which are excellent free radical scavengers due to their electron structure. Plant seed oil extraction, carried out in an oxygen-deprived environment, yields excellent quality oil as compared to traditional high-temperature and solvent extraction methods. When using cold pressing, nothing is added to the seed or to the oil. The oils are potent, pure and unadulterated. Without solvents, bleaching agents or high temperatures, these legendary botanical seeds release their nutrient-dense oil containing a diverse array of nutrients, including omega-3 essential fatty acids and potent antioxidants. Oils produced by this process might accelerate the activity of the immune system and could play a role in moderating the aging process.
ORAC is an analytical measure-ment that represents the total antioxidant value of an oil-soluble or water-soluble substance, and demonstrates the potency created by the cold press process. Lab data at the University of Minnesota, collaborated by work at the University of Maryland and by Brunswick Laboratories, has verified the ORAC values and vitamin E content. Independent work at the University of Minnesota demonstrates the effect of the high-antioxidant cold-press oils in stimulating a marked increase effect on the immune system (evaluating T8 and NK cells) when the organism is subjected to foreign tumor cells. The oils of black raspberry seed and black cumin catalyze and are synergistic in reducing liver metastasis in a colon cancer experimental model using genetically engineered bacteria with an attached human Interleukin-2 gene. These experiments and others verify the potency of the cold-press oils and their therapeutic effect on boosting the immune system.1,2
Collaborative effort with the University of Maryland also has demonstrated a higher inflammatory index of a number of the cold-press oils than aspirin, without the complications associated with the latter.3 Used properly, these oils and others carried out in an oxygen-deprived environment should be advantageous in the support of the immune system and in certain problems where inflammation occurs. Recent laboratory observations have demonstrated a phenomenon of antioxidant synergism when black cumin oil is combined with other oils. The antioxidant values of combined black cumin oil and other oil are increased over the expected weighted average of the individual component parts. Also, when more than two oils are added to the black cumin oil, an even higher antioxidant level occurs than would be expected again by the weighted average. These super-potent antioxidant values in blends of black cumin and other oils can be added to our armamentarium for hopefully preventing many disease processes from progressing. It also is important to recognize that the common oils sold over the counter, such as canola, sesame seed, flax, and sunflower, have low antioxidant values when compared to the cold-press oils with synergism.
It follows that multiple antioxidants are thus better than single antioxidants – an observation known for many years. The “timing” or modulation of the immune system and neutralization of free radicals by this important observation, producing higher antioxidant levels of well-recognized nutrients, might play a role in moderating the aging process and affect a number of diseases produced by a gradual increase in free radicals.
It also is important to recognize the overall role of black cumin oil in this process. This oil, containing the antioxidant thymoquinone, which in turn promotes the production of prostaglandins E1, is the modulator of the immune T-cell response. Black raspberry oil also modulated the immune response by increasing T8 and NK cells in a colon cancer model at the University of Minnesota. Clinical trials are underway to evaluate these observations.
A free-radical test called “CHECK UP” has been designed to measure oxidized fat in the urine by evaluating the level of the breakdown product, malondialdehyde. The test is simple and has a color chart to evaluate the level of these oxidized radicals. It’s a warning, if high, to add antioxidants, change your diet, or be evaluated for chronic diseases. This should be a helpful addition to the armamentarium of professionals, and the patient, in judging and evaluating therapy.

Cold-Pressed Oils: Synergy of Black Cumin With Other Oils
Multi-antioxidants, with addition of black cumin produced by plant seed oil extraction, can yield super-potent antioxidants greater than their weighted averages (synergism). Black caraway adds stability.
