YL Thieves (PLEASE SHARE!)
For those of you who don't use Twitter, based on my analysis, I was able to closely approximate YL Thieves with this formula (by weight):
Clove Bud 40%
Lemon 30%
Cinnamon Bark 15%
Eucalyptus 10%
Rosemary 5%
I always formulate with a digital scale in grams, so if you wanted to make 10g just divide each % by 10 and that's the number of grams you'd use. You can replace the % with drops or ml but the odor will be too strong in clove and cinnamon bark because those oils have a density greater than 1.0 g/ml and the other oils are about 0.9 g/ml. This is why it's always best to formulate blends by weight for better accuracy and repeatability.
Interestingly, YL charges $51.64 retail for a 15ml bottle blend (or $39.25 if you qualify for discount price, see pic below from YL website). But if you were to make this blend yourself, using single oils purchased from YL, your cost for a 15 ml bottle would be about $26.51.
If you bought all the ingredients from another reputable supplier like Desrosiers in 15 ml sizes your cost for the blend is about $15.40 for 15 ml. If you bought ingredients in 4 oz sizes the cost for the blend goes down to $11.55 for 15 ml.
But If you can buy in reasonable wholesale/bulk quantities from a reputable supplier then the oil cost for 15 ml of this blend is less than $1 !! Imagine how cheap the cost is for a company like YL who buys each of these oils in ton quantities, I estimate the cost they have in each 15 ml bottle is less than 50 cents!
