The seeds of ''Camellia sinensis'' and ''Camellia oleifera'' can be pressed to yield [[tea oil]], a sweetish seasoning and cooking oil that should not be confused with tea tree oil, an essential oil that is used for medical and cosmetic purposes, and originates from the leaves of a different plant.

The leaves are 4–15cm long and 2–5cm broad. Fresh leaves contain about 4% [[caffeine]]. The young, light green leaves are preferably harvested for tea production; they have short white hairs on the underside. Older leaves are deeper green. Different leaf ages produce differing tea qualities, since their chemical compositions are different. Usually, the tip (bud) and the first two to three leaves are harvested for processing. This hand picking is repeated every one to two weeks.
