The plant is commonly harvested from the wild for local use as a tea.
Camellia crassicolumna has a large range and a population size of over 10,000 individuals. It is threatened by over harvesting for its leaves for tea and the clearing of its habitat for other crops. However, the rate and effect of this harvesting on mature individuals and the population are unknown. It is also not clear what proportion of the population is affected by these threats, and more research is needed on this species. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2013)[

Species in this genus generally prefer a peaty, more or less lime-free soil with a pH in the range 5 - 7, but most will grow well in an open loam to which ample leaf-mould has been added, so long as it is well-drained and lime-free. Most species are understorey plants in forests (preferably oak or pine) and prefer a warm, sheltered position with moderate shade; at least at the hottest time of day[
