The ‘strength’ of an extract is often expressed as a ratio. When reading labels on herbal products, you will notice the ratios expressed as 2 numbers inside a parenthesis, such as (1:5) or (12:1). This number expresses the ratio of plant material (by weight) to solvent (by volume). The higher the first number, the stronger the extract. When using natural solvents, the best ratio would be (1:1). Several companies are now expressing ratios of a much higher number. One example is Astragalus (12:1). Anything over (1:1) indicates that additional ingredients have been added, other than the holistically balanced components as they would exist in nature. In order to get these high ratios, a chemical solvent is often used such as hexane or benzene. Nature’s Answer uses only pure natural solvents and ends with a product that is Holistically Balanced™ with a true ratio of all naturally occurring plant components.
In The Beginning The Bio-Chelated¨ process describes a proprietary cold extraction technique developed by Mr. Frank D'Amelio Sr., founder and owner of Nature's Answer¨, and well- respected author*. Long before Nature's Answer¨ was formed (early 1970's), Mr. D'Amelio was immersed in the study of botanical medicine, researching the various herbal texts including the national USP/N.F. (United States Pharmacopeia/National Formularies) dating back to the mid -1800's. (The USP/N.F. is a reference source that provides manufacturing standards and extraction techniques used to make herbal formulas; these standards were considered official prior to 1938.) This authoritative formulary discussed the use of plant parts such as leaf, stem, bark, flowers and roots. It recommended certain solvents known as "menstruums", in which plant parts were soaked in order to extract their active constituents. High heat was also often utilized to concentrate the extract. Mr. D'Amelio noticed that high amounts of solvents, usually alcohol, were often recommended, and that sediment would fall to the bottom (precipitate) in certain solutions. He began to investigate how he could offer the consumer potent herbal products made with very low heat, with minimum precipitation, and without a lot of alcohol!
A Clue From Nature In working towards the goal of attaining a final botanical extract product with little alcohol, Mr. D'Amelio turned to Nature for the apparent answer. He realized that plants were composed of 80-85% water as well as some alcohols, fats, etc. If plants were able to keep the active constituents in solution and use them as needed mainly through water, not alcohol or other solvents, why couldn't he? Thus, he began a long, in-depth series of experiments with many different plants. Through rigorous research protocols and scientific testing, he discovered that the active constituents of some plants could be extracted using lower alcohol amounts with water and other natural solvents such as organic apple cider vinegar or vegetable glycerine. At other times, however, higher alcohol was necessary, such as when he was extracting volatile oils like menthol from peppermint. The experimentation process continued, with Mr. D'Amelio documenting the optimum menstruum combinations required for each plant to yield the maximum beneficial components. (Note that there are differences in alcohol. The alcohol consumed in wine and beer is derived through a natural fermentation process with no processing other than filtration. When distilled alcohol is added to an extraction, which some herbal manufacturers use, it effects the body in a more detrimental way; thus the development of the Bio-Chelation¨ process, which uses only organic alcohol).
The Bio-Chelated¨ Method Is Developed As Mr. D'Amelio continued his experimentation with various plants and menstruums, his extraction processes became more refined, and eventually led to the development of the Bio-Chelated¨ method. The Bio-Chelated¨ method incorporates soaking for a period of time, using different menstruum ratios for different plants to optimize their therapeutic values. Furthermore, this procedure offers additional significant advantages when compared with other types of extraction processes commonly employed by competitors in the herbal industry.
Bio-Chelation includes the use of "cold extraction", where the plant parts are extracted without being exposed to excessive amounts of heat. Cold extraction helps the herb maintain vital minerals and other trace elements in solution, thus enabling the herb to keep its Holistic Balanceª intact. (Holistic Balanceª means that extracts retain as many of the natural constituents of the original plant as possible.) In addition, the Bio-Chelated¨ process incorporates the use of an exclusive technique that removes much of the alcohol used during the menstruum soaking (maceration) phase, replacing it with vegetable glycerin instead. The resulting yield is an herbal extract that is either alcohol-free, or has a low alcohol content. (Both alcohol-free and low alcohol products from Nature's Answer feature vegetable glycerin only. Glycerin is used because it helps bind certain plant constituents, is natural to the body, is easily absorbed by the cells and has little insulin response. Only vegetable glycerin has been used since 1972. In addition, all alcohol used in Nature's Answer's low alcohol formulas is certified organic.)
The Bio-Chelated¨ method was the first extraction process to yield a 12-14% alcohol extract in the herbal industry!
Nature's Answer Stands The Test of Time Over the last quarter of a century (since 1972), the Bio-Chelated¨ cold extraction process has been painstakingly tested and proven to stand the test of time. Incorporating Mr. D'Amelio's proprietary cold extraction process in today's manufacturing procedures continues to yield a measurably superior product. One such example is Saw Palmetto from Nature's Answer¨, a product that is produced utilizing our Bio-Chelated¨ method versus the more expensive CO2 method. Our Bio-Chelated¨, cold extraction process yields a product that not only contains the same amounts of active constituents as the more expensive CO2 extracted product, but features a higher percentage of polyphenols, the compounds responsible for the herb's antioxidant properties. The end result is a Saw Palmetto extract that maintains its holistic balance! (Note that most prior successful studies done on Saw Palmetto utilized grain alcohol extracts which contained naturally occurring polyphenols; the CO2 extracted products do not contain polyphenols!) Although larger quantities of herbal products are now being produced as compared to the earlier experimental batches made by Frank D'Amelio, his founding corporate philosophy remains intact - combine the greatest care with the highest quality of raw material to create the ultimate herbal extract that works. After all, that's what it's all about, isn't it? Bio-Chelated¨..Another reason to count on Nature's Answer Without Question! Manufacturing Highlights:
