at least one flavonoid with the o-hydroxy phenolic moiety. 
Thus, on theoretical grounds, one would predict the formation 
of carcinogenic N-nitroso compounds in marihuana treated with 
nitrate-containing liquid fertilizers. The implications of this 
possibility are obvious. 
2. PHENYLPROPENES 
Araceae 
Acorus L. 
There is some evidence that Indians of northern Canada chew 
the root of Acorus Calamus L.—flag root, rat root, sweet 
calomel—for its medicinal and stimulant properties. In excessive 
doses, this root is known to induce strong visual hallucinations 
(Hoffer and Osmund 1967). The hallucinogenic principles are 
reported possibly to be a-asarone (I) and £-asarone (II) (Schultes 
1970c). There are two species of Acorus occurring in the north 
temperate zone and in the warmer parts of both hemispheres.
