For treatment purposes Skullcap can be taken in the form of tea or as a tincture which is made from fresh Skullcap. Only 1/3 - 3/4 of a teaspoon, or 2 ml-4ml, of the Skullcap tincture may be taken three times a day.
You can safely use skullcap in the amounts stated above, however pregnant and breast-feeding mothers should avoid using skullcap as there is limited information about its safety towards babies. There have also been a few cases of liver damage associated with Skullcap but studies are yet inconclusive and it may be due to adulteration of the herb with germander, or Teucrium Chamaedrys, which is also sold as pink Skullcap.
When buying herbs make sure that you only get the best available and make sure that your herbalist is a qualified professional able to help you properly.
