While I consider slippery elm safer than coffee, LRNP (March 1991) says, “preparations of slippery
elm had been used as abortifacients.” Perhaps they refer to Foster and Duke, who note slivers of
bark being used mechanically to induce an abortion, sort of the herbal coat hanger. Oleoresins from
several elm species can cause dermatosis. Pollen is allergenic (CRC; LRNP, March 1991). But even
conservative CAN says, “it would appear to be non-toxic.” The copious mucilage of the inner bark
justifies its use as antitussive, demulcent, and emollient (CAN).SLOE, BLACKTHORN (Prunus spinosa L.) ++Activities (Sloe) — Antipyretic (f; EFS); Astringent (1; EFS; PHR; PH2); Cardiotonic (f; MAD);
