I’ll never forget the first time I opened a bottle of vetiver essential oil. I had heard some positive things about it, so I ordered some. When I opened the bottle, I was immediately disappointed. I was reminded about house hunting in South Phoenix several years ago, particularly the smell of a home that had been foreclosed on and the residents burned the place on their way out. It smelled unmistakably like burned wood and housing materials. Very unpleasant.
Most earthy essential oils (vetiver, patchouli, etc.) do have a strong scent. Keep that in mind. It seems that people either love them or hate them.
