Tea oil is a sweet seasoning and cooking oil made by pressing the seeds of C. oleifera, C. japonica, and to a lesser extent other species such as C. crapnelliana, C. reticulata, C. sasanqua and C. sinensis. Relatively little-known outside East Asia, it is the most important cooking oil for hundreds of millions of people, particularly in southern China.

Given their genetic differences forming distinct clades, Chinese Assam type tea ( C. s. var. assamica) may have two different parentages – one being found in southern Yunnan ( Xishuangbanna, Pu'er City) and the other in western Yunnan ( Lincang, Baoshan). Many types of Southern Yunnan Assam tea have been hybridized with the closely related species Camellia taliensis. Unlike Southern Yunnan Assam tea, Western Yunnan Assam tea shares many genetic similarities with Indian Assam type tea (also C. s. var. assamica). Thus, Western Yunnan Assam tea and Indian Assam tea both may have originated from the same parent plant in the area where southwestern China, Indo-Burma, and Tibet meet. However, as the Indian Assam tea shares no haplotypes with Western Yunnan Assam tea, Indian Assam tea is likely to have originated from an independent domestication. Some Indian Assam tea appears to have hybridized with the species Camellia pubicosta. [12] [13] Carvalho, P.I.N.; Osorio-Tobón, J.F.; Rostagno, M.A.; Petenate, A.J.; Meireles, M.A.A.
