Silphium plant
The Silphium plant is a Libyan wild plant whose original and only homeland is present-day Libya. It was a plant that had a wondrous ability to treat incurable diseases and was used as a spice, disinfectant, and antiseptic. It was valued more than gold and money, especially during the reign of the Greeks and Amazighs in the society of Cyrene and its environs.
It has a long stem with leaves on its sides, distinguished by a flower at the top
Silphium was printed on Cyrene coins as a national identity for that era, as it carried a great honorary character and identity for that era, as the silphium plant formed the basis of trade in the city, and the plant was essential to its thriving economy, so its fame contributed to the emergence of an economic movement in the Cyrenean ports...
Studies say that the plant has become extinct due to poor harvest from Libyan farmers. Due to the high demand for it, residents used to give it as taxes or to buy their needs instead of money...
