A tincture is a concentrated liquid form of one or more herbs, which is made by soaking the bark, berries, leaves (dried or fresh), or roots from one or more plants in alcohol or vinegar. The alcohol or vinegar pulls out the active ingredients in the plant parts, concentrating them as a liquid. Tinctures are a key component of traditional herbal medicine and have been used for millennia. They are usually taken orally by using a dropper to place the liquid under the tongue. Tinctures can be made with various ethanol concentrations, which should be at least 20% alcohol for preservation purposes. Some common plants used for tinctures that scientific studies suggest can benefit your health include chamomile, echinacea, and ginseng. Tinctures are often used to relieve a wide range of health issues, including indigestion, stress, PMS, pain, and insomnia. However, it is important to exercise caution when using tinctures, as their health effects are unclear and not well-studied. It is recommended to consult a doctor before starting any type of herbal remedy regimen.
