I love the aromas, the surprisingly effective impact they have on health--and yes, the chemistry! I'm especially interested in essential oil components. I've been blending from a component perspective for many years now, and have found the approach really effective.
Component Blending with Sitka Spruce
Let's consider Sitka Spruce (Picea sitchensis). Sitka has a nice percentage of beta myrcene (β-myrcene). I like β-myrcene. (I admit, I have molecular preferences--come on don't you?) As molecular structures go, beta myrcene seems simple, sweet, helpful and easy to relate to. I know, calling a molecule "sweet" means that some people have just closed their browsers and are no longer reading this post!
