Since oils are concentrated, any pesticides on the original plant are also concentrated. Organic-certified oils are safer for ingestion. A Note on Safety
has their "Ingestible" labels (often identified by a "Supplement Facts" panel on the bottle).These brands provide extensive third-party testing (GC/MS reports) to ensure the oil is pure and free of synthetic fillers or pesticides, which is critical when ingesting them.
Check the manufacturer’s website to see if the oil is on the FDA’s GRAS list.
The most reliable source is often a company that specializes in baking and confectionery supplies. Brands like LorAnn Oils are industry standards; they produce "SS" (super strength) flavors and oils specifically designed for candy making, chocolates, and baking. These are clearly labeled for internal use and are often found in craft stores like Michaels or specialized baking shops.
For those using oils in large-scale production, wholesalers like Mountain Rose Herbs or Plant Therapy offer organic options. They provide detailed documentation regarding the extraction method (e.g., steam distilled vs. cold-pressed) and purity levels. What to Look For (The Safety Checklist)
