Mandrakes, Memory Foods, and the Evil Eye in Nature

Kabbalah & Mysticism Jewish Magic and Superstition, Ch. 12
Curated by The Jewish Mythology Team ·

Medieval Jewish folk belief wove a dense web of connections between the natural world and the supernatural. Certain plants healed. Certain foods enhanced memory or destroyed it. The human body itself was a battleground where invisible forces struggled for influence. SAFE0 Trachtenberg traced these beliefs from their Talmudic roots through the elaborate folklore of the Rhineland and French Jewish communities.

The most famous magical plant was the mandrake—the <i>duda'im</i> of (Genesis 30:14), which Rachel bargained from Leah. Medieval Jews inherited the widespread ancient belief that pulling a mandrake from the ground was lethal. Rashi, in the 11th century, still identified the <i>yadu'a</i> mentioned in the Talmud (Sanhedrin 65a) with a plant-animal hybrid used in magical rites. Louis Ginzberg traced the legend's Jewish origins, noting that the idea of a death-bringing plant was ancient, while its transformation into a "vegetable human" was a later, likely Germanic addition.

Food carried magical properties far beyond nutrition. Garlic was prized as an aphrodisiac since antiquity—the Talmud itself endorses it. Certain foods before intimacy could determine the character of children conceived. The Sefer Hasidim and Ziyuni recorded beliefs about foods that strengthened or weakened memory: some items sharpened the mind while others—particularly leftovers and certain bread crusts—caused forgetfulness. Cutting fingernails in proper order on Friday before Shabbat (the Sabbath) was believed to protect memory, recorded by Isserles in the Shulhan Arukh.

Eleazar of Worms, the great 13th-century Hasidei Ashkenaz master, catalogued physical signs that revealed a person's inner nature—a system strikingly parallel to physiognomic texts circulating in contemporary Latin literature. The body was readable. Birthmarks, hair patterns, and facial features all disclosed destiny. These "signs" drew on the same impulse that drove astrology: the conviction that the invisible world left legible traces on the visible one.
