Ferula tingitana, the giant Tangier fennel, is a species of the Apiaceae genus Ferula. Despite the name, the plant is not a type of fennel proper, which belongs to another genus (Foeniculum).
This species has been considered to have abortive and menstruation-inducing properties.[7] The species has been suggested as a possible identity for the controversial silphium, a plant used as a spice and for various medical purposes in classical antiquity in the Mediterranean region.[8] Among the many uses of silphium was promoting menstruation, and possibly contraceptive or abortifacient properties, which has been suggested to link it to Ferula.
