Korumba
Native to the Kashitir Jungle on planet Krell, the korumba tree is naturally tall, with a straight trunk and rough bark, and upwards-curving branches that emerge only half-way up its trunk. Its pale green leaves each have three points, and grow in clusters around tiny black fruits that resemble both a nut and a berry.
The leaves of the korumba tree produce a chemical that, when digested, provides a mild muscle relaxant and a slow release of mental stimulants, resulting in culturally normalized substance that has found itself a comfortable niche between herbal medicine and performance-enhancing drug. When the leaves are refined in different stages of growth and with different processes, chemists are able produce two illicit substances from this normally-innocuous leaf.
Young leaves, when steeped together in total darkness and water, reduce down to a bitter paste that is a proven sedative and mild hallucinogen, named loco-tea to allude to the more acceptable moh-tea grown on Krell.
Older leaves, from the tops of the trees best exposed to sunlight, have gradually broken down the more soporific effects via photosynthesis, allowing vast quantities of foliage to be dessicated, processed and compacted into tawny brown bars of stringy leaves that serve as a popular recreational psychoactive and aphrodisiac drug, which is smoked by partygoers across the planet.
