## Frequently asked questions

### What does grand fir smell like?

Bright, fresh, and green — a clean fir-forest aroma driven by its β-pinene and β-phellandrene. It's popular in uplifting, invigorating conifer blends.

### How is fir different from spruce and pine?

They're all conifer needle oils with overlapping chemistry, but the balance differs — firs like grand fir lean fresh and green (β-pinene/phellandrene), spruces lean soft and sweet (bornyl acetate), and pines lean sharp and resinous (α-pinene).

### Is grand fir phototoxic?

No — it isn't phototoxic, so there's no sun-exposure restriction. Dilute it for topical use and store it well to prevent oxidation.
