Alepidea is a genus of about twenty species in the botanical family Apiaceae, all of which are native to Africa. They are mostly erect, biennial or perennial, herbs that occur mainly in southern Africa but are found as far north as Ethiopia.

Alepidea amatymbica, commonly known as African Dream Root, Larger Tinsel Flower, Kalmoes, iqwili, ikhathazo, and lesoko, is a vigorous, indigenous South African plant that can grow up to 2 meters tall in grasslands. The flower stalk is hollow, with dense clusters of small white flowers arranged in rounded heads at the top. This species is widely distributed across the summer rainfall grasslands of southern Africa, extending along the east coast as far as Zimbabwe, and northward into Kenya and Ethiopia.

Alepidea amatymbica has numerous ethnobotanical and medicinal applications. The dried rhizome and roots are smoked or powdered and taken as snuff by diviners and healers to aid in communication with ancestors and enhance divination practices. Smoking the roots induces sedation and vivid dreams. Elderly individuals use the powdered rhizome as snuff or smoke the roots to alleviate headaches. The rhizome is also carried as a magical charm for good luck and is used to treat colds, asthma, and flu. Additionally, the roots are sometimes mixed with marijuana for smoking, as the smoke of Alepidea amatymbica masks the scent of the marijuana herb.

The plant is also valued for self-fortification and protection against evil spirits. In certain traditions, the divining bones of ancestors are cleansed with ikhathazo. The rhizomes and roots contain high levels of diterpenoids of the kaurene type, with dehydrokaurenoic acids and kaurenoic acids being the primary compounds, particularly ent-16-kauren-19-oic acid, which is typically the most abundant.
