Extracts from plants have been used as early back as Egyptian times both for medicinal and cosmetic purposes. Holistic healing with herbs and plants is definitely not a new practice, but it is a forgotten practice.
I use essential oils for my family like this:
Diffusing essential oils in our home (lavender before bedtime makes for a peaceful night’s sleep). Rubbing essential oils on the feet (with a carrier oil) when my kids need an immune boost…and so much more.
