- About Adesium -
Nature's gifts often are destroyed after a corporation with a factory gets involved, since corporate bodies often add their share of mass farmed ingredients like soybean and rapeseed (canola) oils. We do the opposite, using glass containers and bottling in the growing region, in a facility that is small enough to monitor continuously. Absolutely no mass corporate products are bottled alongside our small-scale offerings.
We’re passionate about making naturally healthy products that keep you feeling young deep into your nineties. These products contain ingredients that have been proven health-wise for thousands of years.
The oils corporations use as the main ingredient in their products are made using extraction methods that are unfit for consumption. We don't recommend even using them on your skin. Their refining process, the extracting method from the original source of the oil (the seeds, fruits or other oil-bearing raw materials) involves solvent extraction. This process is often carried out in the country of origin, so the conditions may be worse than I describe them in the following paragraphs.
More than half of the oil in seeds/beans can be removed by mechanically pressing it cold, without solvent use, but the rest of the oil is left in the solids; the process uses considerable horsepower, there is considerable wear and maintenance, and it takes many machines for high capacity. In comparison, solvent extraction with hexane (the primary solvent used worldwide) will remove over 99% of oil, uses less horse power, and requires less maintenance. It is relatively efficient and reliable, and this is one reason why solvent extraction is the primary means of separating large tonnages of oil from the meal.
Why hexane? Actually, it is not a pure n-hexane but a mix of isomers with very similar properties sometimes called extraction hexane or commercial hexane. The properties shown in Table 1 are listed in the NFPA-36 safety standard for solvent extraction. It does appear to have slightly greater ability to extract oil from oilseeds than does pure n-hexane, perhaps due to the variety of isomers present. Hexane has about the best characteristics of the many solvents tried over the years. With a boiling point of 156°F (69°C), it is a liquid in all but the most extreme climates of the world. With a fairly high volatility and a low sensible heat of 144 Btu/lb (335 kJ/kg), it is relatively easy to remove from the solids and oil with low energy use. It has an azeotrope, a slightly reduced 143°F (61.6°C) boiling temperature when in the presence of water or steam and resulting in a vapor coming off at about 95% by weight hexane and 5% by weight water. The azeotrope is convenient for efficient removal of the solvent from solids (or “meal”) using direct steam contact. Hexane has a long record of use without as much irritation of human skin or the immediate severe toxicity of many competitive solvents. It does not mix with water, allowing fairly simple processes to keep it in the system while water passes through the extraction process as moisture in the seed, meal, oil or air. Hexane has a good and aggressive capability to dissolve and mix with vegetable oils so that it can wash the desired oils out of a fibrous or solid material. It is selective and leaves the proteins, sugars and some undesired gums largely undisturbed in the meal. Last but not least, hexane has a relatively ‘tolerable’ odor and a low tendency to cause discomfort when one is subjected to a brief exposure.

Why not use other solvents? Hexane has maintained the dominant position as a solvent for the major plants which extract oil from oilseeds. Every so often the media discusses a new solvent or means of extraction which may replace solvent extraction with hexane, but (so far) the existing technology has sufficient virtues to maintain credibility while it continues to be developed in a competitive market. Widespread use and familiarity ensures that many people and resources will continue to improve on stubborn problems and optimize the hexane process. There is also the advantage of well-understood industry expectations for performance, the availability of trained personnel, and established standards for safe use. Any proposed replacement must exceed hexane’s basic advantages and still might be expected to require a lot of time, development and capital investment to work as well.
It should be noted that other solvents may be required to produce different and specific products. For example, an alcohol-water mixture is used in an additional extraction step (after hexane extraction) to produce soy protein concentrate (or “SPC”) by removing the sugars from standard soybean meal. Various alcohols, isohexane, heptane, butane – many other solvents have found applications in niche markets. For the standard oil removal plant, only isohexane – an isomer with properties very close to hexane - has replaced hexane in a significant number of extraction plants. Hexane is my focus here since it is still the highest volume and most commonly used.
Plant location for large-scale solvent extraction plants?
Most extraction systems are located near rail lines suitable to moving the very large volumes of oilseed and products. The plants are often large enough to process 6000 tons of seed per day, and require a city large enough to provide mechanical services, operating staff, reliable electric power, etc. There are perhaps 55 commercial-scale plants in the USA. If you eat food out a box from a factory, chances are that your body is being stressed regularly by these low-cost oil products.

Why Wild´Picked Organic Oils?
We delight in helping people use healing plants in everyday life, while eating really great tasting food … and becoming healing to their bodies again. We recommend keeping away from factory-made corporate foods, and focusing on wild-grown plants, fruit, vegetables, and minimal animal product foods.
We are helping people feel their best and have the greatest lifespan and energy they can attain. Mass-farmed products that use commercial fertilizers, pesticides, and genetically-modified seeds can not nourish our bodies properly, often creating more stress than good. Pasteurizing foods kills enzymes and nutrients, changing the effects the foods would have on our bodies if eaten without being heated above 150 degrees.
You don't have to be a Healing Foods Specialist to know that cold pressed oils give us immune-benefiting components, antioxidants, and have substances that trigger the inflame/anti-inflame healing process, and more.
Olive oil is an oil that humans have used for centuries with healthful results. It is full of natural antioxidants, like Vitamin E, which defend your cells and tissues from free radical damage. It has healing and anti-inflammatory effects, stimulates bile flow (important for the digestion of fats and for avoiding constipation), stimulates liver and pancreatic enzymes, has anticancer effects, as well antibacterial and antiviral properties. It’s been shown to improve brain cell maturing and function. It has many components that are important besides Omega-3 and Omega-6…such as beta carotene, chlorophyll, squalene, phytosterols, triterpenic substances, and oleic acid (Omega-9). These important substances are easily destroyed by refining and heating.
I recommend olive oil be bought, and served, unrefined, cold pressed and raw as it is sensitive to heat damage.
Look for unrefined extra virgin olive oil from a company you can trust, as most of the olive oil on the market has been blended with cheaper vegetable oils. Extra virgin olive oil has been processed at low temperatures, without chemicals.
As a family, we visit Greece 5 times a year from our Bavarian home, so we can watch exactly how careful our family's oil production process is, from start to finish. The bottling is done within a couple days of olive picking, ensuring no other oils are mixed into the product you receive in our bottles. The wet winters and very dry summers in Kalamata, along with the grazing animal fertilizers used on our olive orchards, create the greatest environment for our olives. My family has been producing this quality of oil for tens of centuries in the Messinian valley Kalamata is located in. We invite you to come to one of our immersion programs to see the amazing environment and process involved in our product bottling.
Our immersions are performed far from modern civilization, cities, factories, and highways to allow a deep mental involvement required for learning abstract concepts in a 5 day course. The absence of external factors within an open air setting creates a learning environment where we can focus without distraction.
