I am trying to make up my own mixture of Deep Blue for my cousin who is 70 years old, and who is not on any type of medication as well as for a lady who is 80 after they suffered from a nasty bout of a virus from a mosquito in the caribbean which cause inflammation and joint pains – I have bought all the ingredients, including wintergreen, which you said is poisonous – could you tell me the dosage of the different oils being used namely wintergreen, camphor; peppermint; blue tansy; german chamomile; helichrysum and osmanthus – in the synergistic mix – how many drops of all these oils to make up the mix? I will make up the mix and the post it in a 10 ml bottle to my cousin with specific instructions. I should appreciate your advise.
Sadly there is a wide discrepancy in the quality that is reflected in the price. The less expensive brands I have ended up using for cleaning the house. Edens Garden oils smell like they are old and dirty. I love Young Living and yes, I have not tried DoTerra. Only because there selection was so limited and I felt there wouldn’t be much differenance between them and Young Living.

Thank you so much for putting this information together. I really like this site. I am excited to follow it and learn more. I am in a company that does adaptogens and recently started seeing and learning that some of the EO’s are also adaptogens. I started using some and got some terrific results. Lots of stress that has been relieved. Then I had started to lose weight and after about 46 lbs found I could use grapefruit and frankincense and it was helping with taking away the wrinkles a saggy parts. Maybe you could cover this in some of your articles..

Our sense of smell is directly wired to the brain’s centers of memory and emotion. Cells inside the nose detect smells in our environment, and send information to the brain, via the olfactory nerve. (We also have a cluster of cells the top of the throat that detect scents from the food we consume, and pass that information along the same olfactory channel to the brain.) The information about smell does immediately to the limbic system of the brain, which includes regions like the amygdala that control emotional reactions and memory.  
According to Avery, while specific dilutions can vary based on personal needs and individual essential oils, the general rule of thumb is to aim for a one to five percent dilution. "A one percent blend is six drops of essential oil per ounce of carrier, while a five percent blend would be 30 drops per ounce of carrier," she says.
