Àjìjà, often elided as Ààjà, "wild wind",^[1] (called Eziza among the Edo where it is also known)^[2] is the Orisha of the whirlwind, forest, the animals within it and herbal medicine. In his forests he would find plants with medicinal properties and mix the herbs and roots and other plant parts together to find cures for the sick. He holds the secrets of botany and can be also looked to for help with trading and economic prosperity. Ajá shared much of his knowledge with humans waiting for someone to come and find him to share it with. This person was usually a shaman in training, or someone of the like.

It's believed that if someone is carried away by Ajá and then returns, they become a powerful medicine man (Oníṣègùn). Ajija uses the whirlwind to lift, convey or transport people from their abodes into the jungle or some other unknown place to impact unto them the ways of herberlism.^[3] According to legend, when wants to learn the secrets or mysteries of herbs, they wander in the forest until they get lost therein. Ajija then appears to the lost votary who must not show any fear, after which they are taken and taught the curative powers of herbs and plants. Once the lessons are over, they will be guided out of the forest by Ajija.^[4] The journey supposedly will have a duration of between 7 days to 3 months, and the person is thought to have gone to the land of the dead or heaven. Ajá is considered one of the rarest Earth Spirits because he reveals himself to humans and not to harm or scare them.
