The health benefits of using top grade essential oils is far and wide and often dismissed by many because they are unaware of the scientific studies or because they use cheap oils purchased from the store that have been adulterated or diluted and yield little to no health benefits. (They are cheap for a reason!).
SUMMARY
A publicized University of California, Irvine (UCI) study published in the journal Frontiers in Neuroscience in July 2023 found that nightly exposure to essential oils for two hours over six months led to a significant 226% increase in cognitive capacity (measured by a memory test) in older adults, aged 60 - 85, compared to a control group.
The 7 essential oils that were rotated through during the study were:
Rose
Orange
Eucalyptus
Lemon
Peppermint
Rosemary
Lavender
Michael Leon, the study's lead author, noted that memory improvement levels were "far greater than anything that has been reported for healthy older adults".
The findings suggest that using essential oils as a non-invasive olfactory enrichment technique could potentially be an easy way to strengthen memory and stave off dementia by leveraging the direct link between our sense of smell and the brain's memory circuits.
