“New research confirms that a range of aromatherapy essential oils can not only prevent short and long-term memory impairment but reverse it. I highly recommend adding these specific essential oils to a daily preventative holistic regime not only at home but in senior rest homes and clinical settings.” Dorene Peterson, Founding President of ACHS 



The significance of this course is further emphasized by recent research conducted at the University of California, Irvine (UCI)1. This study showed an astonishing correlation between scent exposure during sleep and enhanced cognitive function, offering a glimmer of hope in the battle against dementia. Supported by industry giant Procter & Gamble, the study reinforces the established link between scent and memory, while also hinting at the possibility of a market-ready home-use solution.


The UCI study involved exposing a group of older adults to carefully chosen fragrances during their nightly slumber over a span of six months. The results were astounding. Participants subjected to this olfactory intervention displayed an unprecedented 226% surge in cognitive performance compared to a meticulously selected control group. This remarkable leap in cognitive abilities underscores the potent connection between scent and memory, paving the way for groundbreaking advances in enhancing cognitive function.


The collaboration between the University of California, Irvine, and Procter & Gamble reaches beyond the confines of academic research. It signifies a significant stride toward the development of an innovative home-use product, poised to redefine cognitive enhancement strategies for aging populations. This partnership embodies a commitment to translating cutting-edge scientific findings into tangible solutions that can positively impact lives.


In a world where the fusion of scientific inquiry and holistic practices is reshaping the landscape of wellness, ACHS's Essential Oils for Memory Retention course offers a new paradigm in memory enhancement and cognitive function. Join us on this enlightening journey and learn more about scent-based memory preservation.
