essential oils are highly concentrated compounds extracted from plants to ultimately capture the purest essence of nature. Found in flowers, trees, seeds, fruit and more, essential oils harness the true power of nature and can offer a multitude of uses and benefits. Essential oils have been used for thousands of years for different purposes, and the usage of these oils span the globe. Earliest reports date back to 4500 BC in ancient Egypt as the Egyptians incorporated these aromatic oils in ancient healing practices. In Iran, since ancient times, rose oil and rose water have been used in religious rituals and ceremonies and have been very popular and loved. Distillation is the most common method for isolation of essential oils, but other processes—including enfleurage (extraction by using fat), maceration, solvent extraction, and mechanical pressing—are used for certain products. Younger plants produce more oil than older ones, but old plants are richer in more resinous and darker oils because of the continuing evaporation of the lighter fractions of the oil. Out of the vast number of plant species, essential oils have been well characterized and identified from only a few thousand plants. The extraction method plays a crucial role because essential oils produced through chemical means are not considered authentic and may lose their beneficial properties. Sourcing from a trusted essential oils bulk manufacturers is important to ensure the oil’s purity and effectiveness.
