Onion

Botanical Name: Allium cepa (common onion); also includes related species like Allium fistulosum (green onion, scallion) and Allium proliferum (walking onion) sometimes grouped in folk traditions. Folk Names: Onion, common onion, bulb onion, garden onion, poor man's truffle, stinkweed, stinking lily, devil's rose, Onyon, Unyoun. Parts Used: Fresh or dried bulb (most common magically); onion skins (outer papery layers for coloring/charms); occasionally fresh green tops or seeds. Forms Used: Whole fresh onions for protective charms, warding, or offerings; dried skins for sachets, protective circles, or spell jars; onion-infused oil (external use) for anointing; onion juice for symbolic cleansing.
Note on Identity Onion is a biennial bulb in the Amaryllidaceae family with layered bulbs, hollow green tops, and white spherical flower heads. Its strong, pungent odor and layered structure make it a classic Mars herb of protection, exorcism, purification, healing, banishing, courage, and justice—renowned across cultures for repelling evil, breaking hexes, and "peeling away" deception or negativity. The layers symbolize hidden truths and resilience; the tears it causes represent emotional release. Onion is non-toxic in culinary amounts and safe for external use (bulb edible as food), though its strong odor limits internal magical applications.
History and Etymology
The name "onion" derives from Latin unio ("union" or "large pearl"), for the bulb's layered unity. Ancient Sumerians, Egyptians, Greeks, and Romans revered onion for healing, strength, and protection—Egyptians offered onions to gods and placed them in tombs; Greeks ate it for stamina before battle.
In medieval Europe, onions were hung over doors to ward off plague, witches, and evil spirits; carried to prevent infection or ensure courage. Onion juice was used for warts, wounds, and as a protective rub. In Hoodoo and conjure, onion became a staple for "hot" protection, uncrossing, banishing, and justice work—often cut and placed at corners to "draw out" evil or used in baths to break hexes.
