Traditional Chinese beverage (5,3)
I believe the answer is:
green tea
'traditional chinese beverage' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for green tea that I've seen before include "Teen rage (anag.)" , "Drink - generate (anag)" , "'Asian herbal drink (5,3)'" , "Colourful drink for teenager" , "Healthy drink" .)
