Ritual

Herbs are used in many religions. During the monastic era, monks would cultivate herbs alongside vegetables, while others would be set aside in a physic garden for specific purposes. For example, myrrh (Commiphora myrrha) and frankincense (Boswellia species) in Hellenistic religion, the nine herbs charm in Anglo-Saxon paganism, neem (Azadirachta indica) leaves, bael (Aegele marmelos) leaves, holy basil or tulsi (Ocimum tenuiflorum), turmeric or "haldi" (Curcuma longa), cannabis in Hinduism, and white sage in Wicca. Rastafari also consider cannabis to be a holy plant.

Siberian shamans also used herbs for spiritual purposes. Plants may be used to induce spiritual experiences for rites of passage, such as vision quests in some Native American cultures. The Cherokee use both white sage and cedar for spiritual cleansing and smudging.
