All bottles are plastic and 2oz bottle is a different design from photo.Tinctures contain 40% grain alcohol, rather than what has become the industry standard of 30% or less (watch out for companies that list it as 50 proof, that just means it contains 25% alcohol). Alcohol is what ensures that each tincture is completely sterile and free of any bacteria, spores, or microbes. We also use high quality extracts instead of actual plant material to maximize the concentration of the solutions and minimize the amounts of plant material floating in each tincture. Tincture extracts can be any herb or herbal concoction in an alcohol and other forms. Because alcohol is a universal solvent, it is usually able to extract the essential oils from herbs, as well as extract most of the other chemical compounds the water is unable to extract. But alcoholic tinctures have another, much more important attribute. They absorb into the body faster than any other means of using herbal medicines. This is due to the alcohol base, which starts adsorbing through the stomach wall and even through the mouth upon taking the tincture. Rather than being digested, like other things that are eaten and drunk, the herbs are absorbed right into the bloodstream. Vita Advantage makes all tincture with 40% Alcohol. A well made tincture takes from 8 weeks to 6 months. The alcohol renders it very shelf stable and tinctures can last up to 7 years. Polygonum Multiflorum (Fo Ti) is a very popular plant that has been used for centuries in Traditional Chinese Medicine. It is often referred to in China as he shou wu, which translates to “Black Haired Mr. He”; signifying a man in an ancient tale who took Fo Ti daily to restore his gray hair to its original black color. Native to China and also grown in Taiwan and Japan, the root of the plant is considered to be a longevity tonic. We only use prepared Fo Ti in our tinctures, meaning it has been boiled in a black bean broth. This creates some chemical reactions that make the root much safer for the liver as well as increasing the benefits of longevity and premature graying of hair. This is the method of preparation that has been used for thousands of years since it was first used in Traditional Chinese Medicine.
