From the Byzantium era to nowadays Vikos and the wider region has been known for its medicinal plants, the therapeutic attributes of which are known worldwide. The residents of the nearby villages collected these plants and made various quackeries. Some of them became commercial doctors, named Vikogiatroi or Kompogiannites, because they kept their herbs tied up in knots of handkerchiefs.
These doctors became known in all the Ottoman Empire and many of them settled permanently in Istamboul. Famous Vikogiatroi of Papigo were Cornelio and Zortovoulos.
