Although you live in the UK, it is still possible that you are using an adulterated preparation of Scullcap. Here in the states it is still very common to find Scutellaria adulterated or simply substituted with Teucrium canadense (Germander or Wood Sage). The largest exporter of American botanicals STILL purchases (through local brokers) Blue Skullcap (ANY Scutellaria) and Purple Skullcap (Teucrium). If the scullcap is a tincture or a pill preparation of a solid extract that comes from your side of the ocean it is very probably what it says it is. Many Teucriums, however, contain alkaloids that are potentially damaging to the liver (havn't seen THAT happen) or at least mildly hepatotoxic, causing frontal headaches, morning malaise ... even overly sensitive skin (have seen THAT happen).

Then again, the several species of Scutellarias present subtle but distinct differences in their physiologic actions. Although Scutellaria lateriflora is the "official" species, I have found that S. galericulata (also called S. epilobifolium or E. hyssopifolium in some places) and known generally as Marsh Skullcap is a rather preferable medicine...and I believe it is common in Great Britain and Northern Europe.

Always Buy Local.
