I grew up in a family of multi-generational gardeners. My great-grandfather had a produce stand in the Italian district of Boston where he would sell fresh fruit and vegetables, and my other great-grandfather basically was an urban farmer before urban farming was even a thing.
Essential oils are probably one of those Ayurvedic natural remedies which you may have heard of, or even dabbled a bit in, but for the most part essential oils still seem to be relatively untapped in terms of their wide spread usage for naturopathic remedies.
Specifically when it comes to sleep and relaxation, essential oils have been used for centuries, and for me personally bring about a very immediate feeling of comfort and relaxation. Personally, my favorite of all time essential oil is lavender.
