Essential oil science is producing results that look almost contradictory on first glance, from 8 to 12 log reductions against microbes in lab testing to big swings in how much plant material it takes to make a kilogram of oil. The market is also scaling fast, with the global essential oils market estimated at $9.66 billion in 2023 and a 4.5% CAGR forecast for 2024 to 2032. This post pulls together those lab, supply, regulatory, and consumer signals so you can see where quality and hype actually intersect.
