Dilute with a quarter cup of water before taking. Half a pint of tincture should have the medical efficacy of one ounce of fresh herb, therefore one teaspoon should have the medicinal potency of one cup of infusion. Higher doses can be achieved by doubling the amount of tincture added to the water. You can also combine tinctures together to make a more concentrated mixture. For example, you could mix one part meadow sweet-leaf tea to three parts pine-tree oil to make a relaxing massage oil. This is known as a synergistic blend and any effect from the oil is increased by this combination. Synergistic blends are useful when you want to use less of one ingredient but still get the same result. It is important to note that any alcohol in the tincture will evaporate when diluted with water, thus reducing its effective concentration. It is best to keep tinctures at 100 percent strength unless otherwise recommended by your health care professional.
