In this episode, Tony Frischknecht brings in Nick Gay, the Head of Product Management at Essential Extractions, to discuss the basics of herb extraction. Extraction refers to the process of getting essential oils from herbs. This process works by dissolving the plant’s essential oils in a solvent, then later separating the essential oils from the solvent through temperature and pressure changes, so it yields pure essential oils in the end. Nick explains the two most common forms of herb extraction: steam distillation and CO2 extraction. Between the two, steam distillation is the most common form of extraction used today. Although it’s the easier process, steam distillation can’t be used for heat-sensitive plants like citrus fruits, in which case CO2 extraction is the preferred method.
