I've been very happy with this oil, but as a matter of practice, I use this with a carrier oil. Ginger can be a topical irritant for some people, when used pure. If you do any amount of research, you will find that most, if not all recommendations, are for the use of a carrier oil with the ginger oil. I am very happy with the results from the topical use of this ginger oil.
