Gattis-root was a plant that yielded an extract effective in treating Bybbec fever within the Twi'lek population. The Galactic Empire provided gattis-root extract at no cost on Ryloth; however, recipients needed to register at the dispensing clinic. This registration process enabled the Empire to detect fraudulent identifications and aid in relocating jungle inhabitants. Following the Free Ryloth Movement's unsuccessful endeavor to eliminate Emperor Palpatine and Darth Vader, Hera Syndulla and the Karthakk Group embarked on a smuggling operation to transport gattis-root extract to Ryloth in 13 BBY.
