Below is a tutorial video explaining how to make hydrosols by Nadia Harper RHN, Holistic Nutritionist and Health Advisor. The video can be found on Making Healthy Choices. A hydrosol is the product that remains after roots, barks, plants, flowers, or seeds are steam distilled. A hydrosol can also be the remnants of the essential oil making process. It can be used for aromatherapy or medicinal purposes. It’s fairly cheap and simple to make.
Nadia’s website has written instructions to make a hydrosol, too.
