Local natural food stores (like Whole Foods or independent co-ops) carry brands such as Aura Cacia or NOW Foods . However, you must be careful here: not every bottle from these brands is food-grade. You must check the individual label for a "Supplement Facts" box.

Since oils are concentrated, any pesticides on the original plant are also concentrated. Organic-certified oils are safer for ingestion. A Note on Safety

If a bottle has a "Supplement Facts" panel (like a vitamin bottle), it is labeled for internal use.
