In this video, Elizabeth April discusses the legitimacy of bioresonance devices, specifically the Healy brand. Although Elizabeth April is unfamiliar with that specific brand, they explain the concept of biofeedback devices that scan and provide vibrational frequency feedback based on an individuals energy. Elizabeth April claims that these devices are legitimate and even mentions having interacted with them themselves. However, they caution that results may vary depending on an individuals current state, and advise taking everything with a grain of salt and trusting ones own intuition.
