What this interaction means in plain words
Green tea and Venlafaxine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Green tea belongs to Gastrointestinal Tract; Venlafaxine belongs to Central Nervous System.
Why it happens
