Which oils are generally regarded as "hot" oils

Q: Which oils are generally regarded as "hot" oils?

A: Oregano, lemongrass, thyme, clove, hyssop, and lemon are the ones that are generally regarded as hot.  Everyone's chemical make-up is different, so what may be hot to me, may not be hot to you, and what may be hot to you one time, may not bother you the next time.  It's always a good idea to keep a carrier oil with you just in case you experience a hot oil unexpectedly.
