Corydalis, a flowering herbal plant that is a bitter, slightly acrid and warm herb that has been used effectively as a sedative and tranquilizer. This tuber is a Chinese herb with potent pain-relieving properties. It is traditionally used for neuralgia, menstrual cramps and gastrointestinal spasms. When properly used, Corydalis has been effective in easing palsy, trembling hands and general excitement. It has also been employed to help treat anxiety, restless leg syndrome and has been included in herbal preparations for Parkinson’s disease. As a sedative, Corydalis is said to induce sleep without adverse side effects, which is of great help to those who suffer from insomnia. Corydalis is also considered an herbal analgesic and antispasmodic that diminishes pain. As a painkiller, Corydalis is believed to be especially helpful in cases of dysmenorrhea (painful menstruation) and abdominal pain after childbirth. It is also said to relieve abdominal cramping and spasms (confirming the herb’s historic applications in Traditional Chinese Medicine). It’s painkilling effects also help to relieve headache and lumbago, as well as the pain of traumatic injury. Recent laboratory studies have indicated that the alkaloids in Corydalis possess cardiovascular actions and may help to protect against heart attacks and strokes. Corydalis may be useful in treating stomach ulcers. Corydalis herb appears to act like other drugs in the opium family, modifying the perception of pain by specific centres in the brain. It also has anti-anxiety and sedative effects. Corydalis is usually prescribed by practitioners of traditional Chinese medicine as part of a multi-herb formula based on the patient’s overall condition. 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. HOW TO USE: Extracts/Tinctures are administered under the tongue and absorbed directly into the blood stream. If you find the taste disagreeable, put it under your tongue and chase with juice.
