Essential oils are an excellent substitution for dried herb, and they are easier to carry and store. They contain the vital oils and many of the same constituents of healing herbs. Essential oils are the highly concentrated oils that have been extracted from medicinal herbs. They are so highly concentrated that using them without dilution can be harmful. There are a few exceptions to this rule, but to use essential oils safely and effectively dilution is important. The following is a simple guide to diluting essential oils.
The first thing you will need is a carrier oil. Common carrier oils are olive, grape seed, and jojoba. If you do not intend to wear the oil on your body you can use mineral or castor oil. A dilution of 1% to 3% is common and useful in a blend for the final product. Lower dilutions are suitable for children over 3 and the elderly.
The are the common measurements for essential oils in their pure form.
1/8 oz. = 3.75 ml. 1/4 oz. = 7.5 ml. 1/2 oz. = 15 ml.
1 oz. = 30 ml. 4 oz. = 120 ml. 8 oz. = 237 ml. 16 oz. = 473 ml.
Here are number of drops converted to ounce measurement.
1/8 oz. = 75 drops. 1/4 oz. = 150 drops. 1/2 oz. = 300 drops. 1 oz. = 600 drops.
For a 1% dilution:
If you have 1 oz. of oil or 30 ml. that is the equivalent of 600 pure undiluted drops of oil. If you want a 1% dilution you will need 6 drops out of 600.
1% dilution is 6 drops.
For a 2% dilution:
If you have 1 oz. of oil or 30 ml. that is the equivalent of 600 pure undiluted drops of oil. If you want a 2% dilution you will need 12 drops out of 600.
2% dilution is 12 drops.
For a 3% dilution:
If you have 1 oz. of oil or 30 ml. that is the equivalent of 600 pure undiluted drops of oil. If you want a 3% dilution you will need 18 drops out of 600.
3% dilution is 18 drops.
ALWAYS use essential oils diluted into a carrier oil. For younger persons and the elderly, be sure and use 1% dilution. The only exception is essential oil lavender which can be safely applied without dilution, it is exceptional for burns in it's pure form.
