Bai lai khao and daeng are often exported to Thailand, for $5 kg-$10 per kg. Export to China and Taiwan is also growing. Propagation by division is mainly by rhizomes collected from the forest, The leaves are blended in water which is then drunk, mainly by women who have recently given birth. Plants are dug out or their rhizomes pulled from the ground. About 1 kg-2 kg per person per day can be collected through journeys of 4 km-6 km into the forest. The flowers are found in low light intensity habitat on leaf litter and on mossy rocks near streams.
