Vibrational Infusion is a method that uses intention to receive the benefits of flower essences (such as Andrea Mathiesons Raven Essences) without ingesting them. After developing and using this method for several years, Karin Cremasco found she could also teach others to use this vibrational essence method. Cremasco and Mathieson developed what is essentially a franchising agreement, where Cremasco and her students pay Mathieson, the originator of the essences, a fee for the vibrational use of the essences.
