|Also known as memory root, dragon root is
reputed to have hallucinogenic effects (Schultes
and Farnsworth 1982, 187*; Schultes and Hofmann
1980,366*). There are several potently toxic plants
in the Family Araceae (e.g., Arum, Dieffenbachia,
Dracunculus) as well as such questionable hallucinogens
as sweet flag (Acorus calamus) (cf.
Plowman 1969). The genus Arisaema is known for
its allergenic effects when touched or eaten. Fruits
and other parts of the plant contain microscopically
small needles of crystallized calcium
oxalate, contact with which can lead to heavy
histamine secretion (Turner and Szczawinski
1992, 116*). The homeopathic agent Arum
dracontium hom. is obtained from the flowers of
this plant. The Ojibwa Indians are said to have
used the root to counteract witchcraft (Moerman
1982, 101 *). The related species Arum maculatum1. was used as a wine additive (cf. Vitis vinifera).
