A double extraction means that the mushroom or herb has been extracted in two different, and usually equally important ways. Most mushrooms and herbs undergo a dual extraction of water, known as decoction, and alcohol, known as tincture. There are other solvents such as oil, glycerin, and vinegar. It’s important to select the appropriate solvents to get the most out of your herbal extraction, and each herb varies in its ideal methods and ratios. For mushrooms, the beneficial compounds are primarily alcohol-soluble (triterpenes) and water-soluble (beta-glucans). So in order to get full spectrum benefits, it is necessary to do both. At Mushroom Revival, we go the extra mile to extract our mushrooms with alcohol and water, and then carefully combine the two to create a perfect balance and super potent product. Our mushrooms and herbs are also fine tuned to follow the science and extract them at the optimal alcohol percentages, temperatures, and durations.
