Caj je od biljke Caj sto bi se reklo (pise ispod latinski naziv), ne od pirinca.
Tea is an aromatic beverage prepared by pouring hot or boiling water over cured or fresh leaves of Camellia sinensis, an evergreen shrub native to China, India and other East Asian countries.[3] Tea is also rarely made from the leaves of Camellia taliensis.[4][5][6]
dakle caj je od caja (camellia talienis whatever)
Sve ostalo je - uvarak, infuzija, napitak itd. Mislim sve je ok, kao sto se pasta za zube zove kaladont :D, al cisto da ispadnem pametan.
