Tinctures are liquid extracts made from herbs that you take orally (by mouth), and are usually extracted in alcohol. FSF uses organic food-grade ethanol to produce our concentrated Full Spectrum CBD Hemp Extract, then we blend it to the desired strength using organic extra virgin olive oil. We chose olive oil for many reasons. It can be used sublingually (under the tongue), mixed into a variety of foods and drinks, and used incooking. It can also serve as a moisturizer or massage oil.
