Does using natural ingredients like herbs, lemon, and oils in brushing teeth, or rinsing the mouth with vinegar, salt, lemon, and oils during the day while fasting, break the fast?

1 min readAlso available in العربية

Rinsing the mouth with lemon water or oil while fasting is disliked if done without need. However, it does not invalidate the fast as long as the taste does not reach the throat. Tasting food is disliked if done without need, but there is no harm in it if there is a need, and it does not affect the validity of the fast.
