## Frequently asked questions

### Is tsuga a pine?

No — tsuga is hemlock (Tsuga canadensis), a distinct conifer. Its oil is soft and sweet (bornyl-acetate-rich), closer to a spruce than the sharp, resinous character of true pines.

### What does tsuga smell like?

Soft, sweet, and grounding — a gentle conifer aroma from its bornyl acetate and pinene content, often used in calming forest blends.

### Is tsuga 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.
