Can I use essential oil from an aromatherapy lamp to make perfume?

Yes, let me explain in detail

Essential oils should be plant extracts and are also included in natural plant fragrances. However, the essential oils in aromatherapy lamps are not strictly essential oils. Most of them are blended with artificial flavors. It is an artificial flavor that is chemically synthesized or separated. Essential oils are extracted from natural plants.

As for perfume, you can use natural flavors or synthetic flavors. However, due to human health considerations, safer natural fragrances, namely essential oils, should be chosen instead of the fragrances in aromatherapy lamps to prepare perfumes.
