What’s the difference between Turmeric essential oil and turmeric extract?

There is a distinct difference between essential oils and extracts, and it goes well beyond their aromas. An extract is either a part of the plant dried and ground or soaked in liquid, while an essential oil is the volatile aromatic compounds contained within the plant. The distillation process preserves the unique compounds and their properties that are lost when a plant extract is made. Many of the constituents contained in turmeric extract are too large to survive the steam distillation process,so the extract is predominantly made up of various curcuminoids, while the essential oil is composed primary of sesquiterpenes ar-Turmerone and Turmerone. The different compositions result in a different spectrum of benefits. Turmeric essential oil not only imparts a powerfully warm and spicy aroma, but it also, due to its high concentration of ar-Turmerone and Turmerone, helps support healthy immune and nervous system function when taken internally.* It also has a number of benefits for the skin when applied topically. Though the essential oil and the extract yield different results, they are a power couple when used together.

Is Green Mandarin photosensitive?

Citrus essential oils generally have a photosensitivity warning due to the possible presence of furanocoumarins (organic compounds that bond to DNA and prevent the skin from protecting itself from sunlight). However, we have been unable to detect any of these photosensitive compounds in our source of Green Mandarin. Nonetheless, Green Mandarin has a photosensitivity warning as a precaution. It is categorized as neat, but if you are going to apply Green Mandarin essential oil topically to take advantage of its skin-cleansing and health-supporting properties, we do recommend being cautious while outdoors.

What is the latest research on Copaiba?

With further investigation, we continue to find more benefits from using Copaiba essential oil. In the last three years, we have seen over 50 peer-reviewed publications regarding Copaiba, including our latest AromaTouch® Hand Technique clinical trial, which provided some intriguing evidence of Copaiba’s benefits when applied topically. But internal use is where most of the current research is leading. With its high concentration of endocannabinoid beta-caryophyllene and its ability to influence CB2 receptors, Copaiba may have powerful antioxidant effects and may support the function of several body systems when ingested, especially the immune and nervous systems.* A recent meta-analysis acknowledged a number of recent publications that highlighted Copaiba’s cellular health-supporting and tissue-remodeling benefits. We are just scratching the surface of discovery with Copaiba. Expect more from doTERRA Science on this amazing oil in the future.
