When creating an essential oil blend, the oils are chosen first for their therapeutic effect and then consideration is given to creating the best aroma. This can be done using top, middle, and base notes.

When you create a blend it is called synergy. This means that when certain oils are blended together they have a mutually enhancing effect upon one another so that the effect of the whole is greater than the sum of its individual parts.

BLENDING 

You can use up to 5 essential oils in a blend. Research has shown that you get better results using more than one essential oil at a time. 

You can use up to 5% essential oil, but usually 3% is quite effective. Never use more than 2.5% on the face. Use only 1% in children and elderly. 

When you are treating a localized area for a specific condition it may require a stronger formula. You can experiment with this, gradually increasing the strength until you get the desired response. Another alternative to increasing concentration is choosing alternative forms of absorption (topical and inhalation). 

Once oils are blended they keep for 3-6 months, longer if using fractionated coconut oil or jojoba oil. As long as they have their odour they are good. Oils will start to crystallize around the cap when they have expired and will go "flat". Always keep bottles covered and closed.

BLENDING FORMULA

This formula can be used to determine how many drops of essential oils are required to create any concentration of solution, based on the size of the bottle being used (in mls). 

20 drops = 1 ml of essential oil

Take 20 (drops) X size of bottle (example: 30mls)

20 X 30 = 600

To find 2.5% of 30mls: 2.5 X 600 divided by 100 = 15 drops

RECIPES FOR ROLLER BOTTLES

The recipes below are basic blends that have been tested and are safe for most people. Add the requested number of drops to each roller bottle then fill with a carrier oil of your choice (fractionated Coconut, Jojoba, Sweet Almond etc.), install the roller ball assembly, seal with the cap and shake to mix.
