The primary product of a tea plant is tea leaves. These leaves are processed to produce various types of tea, including green, black, oolong, and white tea. The flavor and aroma of the tea depend on the processing methods used, as well as the specific cultivar of the Camellia sinensis plant from which the leaves are harvested. Tea cultivation is an important agricultural practice, particularly in countries like China, India, and Sri Lanka, where tea has significant cultural and economic value.
