Calamus Root, also known as Sweet Flag, was well-known in Biblical times and mentioned in Exodus 30: 22-25 as one of the ingredients of the ‘holy anointing oil’. This herb has traditionally been smoked, eaten, or brewed into a tea, decoction, extract, tincture and syrup. Widely used north of the equator, Calamus was used by the ancient Greeks, throughout Europe as a medicinal, and by the aboriginal peoples of North America. In the British Isles, its insecticidal and antimicrobial properties made it a favourite to use for thatch. In Ayurvedic tradition, where it is known as Vacha, it is still used as an aphrodisiac.
Caution is advised on the use of this essential oil, since large doses can cause mild hallucinations. The essential oil in the roots of this plant contains the compound asarone. This has tranquillizing and antibiotic activity, but is also potentially toxic. Use well diluted and avoid during pregnancy.
