Ti
The Herbs

Cordyline tenninalis) G

Folk Names: Good Luck Plant, Ki (Hawaiian)

Gender: Masculine

Planet: Jupiter

Element: Fire

Deities:Kane, Lono, Pele

Powers: Protection, Healing

Magical Uses: Ti leaves, when carried on board ship, keep storms away, and when worn ensures that the bearer won’t drown.

Planted around the house the ti creates a type of protective barrier. The green ti should be used for this, not the red variety; though the latter is sacred to Pele, it traditionally gives bad luck to homeowners when planted.

A bit of ti placed beneath the bed protects the sleeper, and a ti leaf rubbed on the head relieves headaches.
