THERE ARE A FEW WAYS TO MAKE AN HERBAL INFUSED OIL
You can choose to make them with a single herb or even multiple herbs. From my research I would lean towards having several single herbal infused oils on hand and later blending the different oils for recipes. This is the best way to get the most out of basic infusions. Take care to use dried herbs so you are not introducing water to your creations, which can cause bacterial growth and nastiness.
Cold/Solar Infusion: This method will require about 4-6 weeks of infusion time, so this is a preferred method. Of course, you obviously need to be prepared ahead of time for this method.
Quick Method: You can utilize a quick, low heat method when you are short on time, but you must be very careful to keep the heat as low as possible so you don’t burn your herbs (think low and slow).
Oven Method: This is another safe and effective low and slow heat method you can utilize when you are short on time.
