You may see oils on the market that have certain properties, such as Love, Money, etc. Now everyone makes these oils differently, but there are ways to make them. Here is how I make Oils used for magickal purposes.
[Now, do not confuse these with essential oils, that is what we are not making, because essential oils are made by distillation.]
First, you will probably want to select a carrier oil. Carrier oils are usually used to cut strong essential oils for use on the skin. However, they can also be used to make oils for magickal use. Common carrier oils include: Extra Virgin Olive Oil, Grape seed Oil, Sweet Almond Oil, or Sunflower Oil. There are plenty more to choose from, and you can use one or the other for different scenarios.
Next, you want to get something to hold your oil. If you are going to make large batches of these oils at a time, mason jars are a great selection. If you are going to be making small batches, you can find various vials and bottles online and at your local store. Many vials come in different colors such as blue or brown.
Now you want to choose your herbs. This can vary due to how you associate with an herb. For example, I may think of cinnamon as an oil for love, while you see it more as an oil for money. You can also items like a petal from a rose your partner recently gave to you as an oil to help/restore love between you and your partner. You can also go by what the book says the herb is used for as well.
After you have done all of that, you want to make the oil. First, place all of your herbs into the container, if you want, you can place your herbs in hand, and speak to them your intention. It's extremely important you get your intention in there one way or another. Once you've placed your herbs into your container, fill it with your carrier oil of choice until you get below the rim of your container [You may want to use a funnel for these steps if you have a small mouthed container such as a vial. You then want to seal it, and store it in a warm place. Some suggest you place it in a sunny windowsill, others say store it in a warm but not sunny area. Let the oil sit for at least one to two weeks. It can sit more if you would like, just give it a shake every once in a while. If you would prefer it, you can strain out the whole herbs to just get the oil. Be sure to label your oils so you know which is which.
