Aromatherapy helps to reduce stress, sets a mood and can be an important part of natural medicine. But essential oils are costly. Making your own saves money and gives you control over the strength of the oil and the quality of the ingredients.
Make sure your slow cooker is spotlessly clean.
Pour the carrier oil into the slow cooker. Add fresh or dry herbs or flowers. Roses from your garden make a deliciously scented oil. Dried herbs from your kitchen, such as basil or mint are excellent to use.
Set the slow cooker to low. Use the timer to remind you to stir with a wooden spoon every 15 minutes for two hours.
Line the strainer with cheesecloth and pour the oil through. Strain at least twice, as any remaining herb will turn the oil rancid.
Let the oil cool and then use the funnel to fill the bottle.
