What is the ruling on massaging the chest with strong-smelling peppermint oil during the daytime in Ramadan?

There is no harm in massaging the chest with peppermint oil during the daytime in Ramadan, even if its smell is strong, because merely smelling a scent does not invalidate the fast, whether it is pleasant or unpleasant, as scent does not have a physical substance that enters the body cavity. The jurists have mentioned that smelling musk, roses, and incense does not invalidate the fast unless the smoke reaches the throat, because a scent has no body.
