This is a great question! I’ve got turmeric in my pantry, though I haven’t used it in my spellwork. I went searching and found a few things. I’ll quote some here and leave you some links!
Nobody seems to be able to agree on what elemental correspondences go with this herb. Some say air, while one source I found said fire. While fire makes sense to me, I would probably say earth.
In India, turmeric seems to function as a sacred anointment. It’s used for brides and grooms during the pre-wedding haldi ceremony, girls entering puberty, and the bodies of the dead. Most of the sources for witchcraft uses of turmeric cite purification as one of its properties, so, while I doubt that its associations in Indian culture are exactly the same, this makes a lot of sense.
Malevolent spirits, particularly the angry dead, can be sent away with the smell of turmeric.
Turmeric is also indicated for spells for healing, strength, and vitality — since it’s a potent medicinal herb and general tonic.
Turmeric’s golden color is useful in color magic. Yellow is associated with abundance and happiness, while gold is associated with the energy of the sun, prosperity, success, and healing. (This sun energy might be an explanation for why turmeric is so useful for purification!)
Turmeric Folklore and Magical Uses – Marble Crow
Turmeric has been used in many cultures for increasing fertility in both humans and animals. Some swear by wearing Turmeric in a charm for good health and protection. For protective purposes in a ritual circle, Turmeric is sometimes sprinkled within its boundaries. In Hawaii, Turmeric is mixed with salt and water, then sprinkled in the area wanting purification such as a sick room or even a ritual circle.
Because Turmeric implies a symbol of purity, fertility and prosperity among the Hindus. It is used in rites and rituals. Turmeric powder along with sandal powder is used in preparing Kalabha to be poured on the presiding deities in temples.
The dried Turmeric roots in Betel leaves called Kumkum are given to the women during the ceremonies as they are considered as a fertility enhancer and bring good luck. Married Hindu women apply this on their forehead longitudinally along the hair partition path to indicate the marital status or smear Turmeric paste on either side of the cheek. Turmeric paste is applied to the skin of the bride and groom before marriage in some parts of India, Bangladesh, and Pakistan, where it is believed to make the skin glow and keep harmful bacteria away from the body.
In southern India, the dried rhizome is often worn in an amulet as protection against evil and to bring about healing or good luck.
