Skullcap is a member of the mint family known as Lamiaceae. It is a hardy perennial that is thought to be native to North America, and can be found growing in marshes, meadows and other damp habitats.
The plant grows to a height of roughly 60 to 80 cm, and produces trumpet-like blue/purple flowers – each of which is just under 1cm in length. The flowers themselves do not often grow at the top of the main stem, but instead grow along the length of the plant’s side branches.
The main compounds in skullcap are:
- Flavonoids, the main of which is scutellarin
- Bitter iridoids, the main of which is catalpol
- Volatile Oils
