Blending oils is an age old tradition in magic practices. Most choose to use olive or coconut oil as a base oil, however, grape seed oil can also be used.
My recommendation for blending an essential oil with a carrier/base oil is 2-3 drops into a 1oz bottle (preferably cobalt blue or dark brown bottles) and fill the bottle with the carrier.
Also, if you’re making a cold infusion, stuff the herbs into the bottle (I like to really get a lot of herbs in there) and fill up with your carrier oil.
Here is a list of essential oil recipes.
