There will be some sediment at the bottom of the cup; for the full effect of this tea, drink it all the way to the bottom! Coca tea is rich in natural alkaloids and it would be best if you could consume it on an empty stomach, between meals or before and after a light meal. Avoid boiling it as that would affect its alkaloid content and eventually the flavor of the tea. Additionally, do not add milk to this tea and avoid consuming it with other milk products like cheese or yogurt.
