Our oils are ethically sourced. We purchase in bulk direct from the manufacturers in different countries, therefore keeping our costs low, with savings we pass on to you. We are not involved in any multi-level marketing, which many of the large suppliers of essential oils are. Our manufacturers engage in comprehensive testing for purity, batch by batch. We work closely with these organisations, confirming all aspects of essential oil quality. We continually research the market, to source the best oils we can.
