A close cousin to the tea plant that makes up one of the most popular drinks in the world, the tea oil camellia is not cultivated for its leaves, but rather its seeds.
The seeds are powdered, steamed and then pressed to produce an oil that is used for cooking across China.
Tea seed oil is also used in soaps, body wash and hair oils, as well as in lubricating and rust proofing solutions.
A recent scientific study found that once the oil had been extracted from the seeds, pressed tea oil camellia shells can be used to make conductors for lithium-ion batteries.
Tea oil camellia is an evergreen shrub that typically grows 3 to 6m tall, with oval-shaped, glossy dark green leaves that grow up to 8cm long. Clusters of many-petaled flowers are white and bloom in early spring.
