Is Guaiazulene natural or synthetic?

Guaiazulene can be either natural or synthetic. It was originally derived from sources such as guaiac wood oil and chamomile, but today it is often produced synthetically to match the naturally occurring compound. Both forms share the same characteristic blue color.
