Tinctures are more powerful and last longer than dried herbs.
It is much cheaper than buying ready made herbal products. You can make about a quart of your own tincture for the price of a few ounces of tincture at retail stores. You can control the quality of the product you are making by starting with herbs you collect yourself or purchase through a reputable source. You are also ensured of the purity of the final product. You can make special combination formulas.
