I’ve been using natural oil based medication such as oregano oil and eucalyptus oil, which require being rubbed onto the skin (bottom of feet, stomach, forehead etc) to treat ailments and sometimes it is recommended to inhale them. Does this invalidate fasting? I don’t taste them, but I smell them.
No, it doesn’t affect your fast as it is not eating or drinking.
