]. The leaves are also exported to ethnic markets in various countries around the world. Current harvesting practices are unsustainable, and so research is being carried out into cultivating the plant commercially. Early trials are promising, with the plant proving relatively easy to propagate.
As a result of overharvesting and increasing demands a decline of the population has been noticed. The increased harvesting of this species, if unchecked and unmanaged, could lead to a drastic reduction in population size, which would then meet the thresholds for a threatened category. The plant is classified as 'Near Threatened' in the IUCN Red List of Threatened Species(2011)[
