Avoid
use with hypersensitivity to any of the apparatus of wormwood, decidedly the essential
oil composition. Theoretically, wormwood may be contraindicated in patients
with an basal birthmark with hepatic heme amalgam because thujone is a porphyrogenic
terpenoid.
Wormwood
is classified as an belling herb by the FDA because of the neurotoxic abeyant
of thujone and its derivatives. Few studies certificate the assurance of
wormwood admitting its continued history of use as a aliment additive. Thujone
bears a apparent structural affinity to camphor, pinene, anethole, and citral.
