A few decades ago, essential oils were used mainly by aromatherapists and barely featured in our daily lives. Now, we use essential oils in everything from cosmetics to household cleaners.

Essential oils are also a mainstay of natural skincare where they are used for their gorgeous scents and also as skin-beneficial ingredients.

However, our use of essential oils is putting pressure on plants, pollinators and the planet's sustainability.

Essential oils are big business for entities like multi-level marketing companies and large cosmetics' manufacturers. Even indie beauty, which generally works in small batches and low volumes, is contributing to the global demand for essential oils.

Lorraine Dallmeier, podcast host and Formula Botanica CEO, talks to Dr Sally Gouldstone, conservationist and Founder of natural skincare company Seilich. Sally puts forward some controversial opinions on essential oil use and starts by asking: "Just how essential to our lives are essential oils?"

This episode challenges Sally to square the circle for natural formulators who want to continue using essential oils, but mindfully and sustainably.
