Wormwood (Artemisia absinthium):

Therapeutic actions:

Anthelmintic, antiparasitic, bitter tonic. (Bone, 2003, p. 469)

Phytochemical constituents that enhance these:

• Bitter sesquiterpene lactones (especially absinthin), flavonoids, hydroxycoumarins, resin, silica, tannins, terpenoids, volatile oil: thujone, isovaleric acid. (Mills, 1994. p. 220) (Bone, 2003, p. 469)

Supporting evidence:

Intravenous administration of wormwood decoction demonstrated a choleretic effect. In an experimental model increased gastric activity and stomach acidity was shown to have occurred after oral administration of absinthin. A clinical study found "a dramatic increase in duodenal levels of pancreatic enzymes and bile" after oral administration of liquid wormwood. (Bone, 2003, p. 470)
