Blue moons generally happen only every 1-2 years. October 31, 2020 is a Full Blue Moon this year. The last blue moon that occurred on Halloween was in 1955. Some may say 2001, but it depends where you live in the world whether or not it was technically considered a blue moon. in any case, the blue moon is simply another full moon, so all the same things apply, but a Full Blue Moon on Samhain is incredibly special from an intention setting standpoint as Samhain is the Witches New Year. So….what do you want to release & make space for & invite into your life? This oil blend has a very floral aroma with notes of rose, lavender, chamomile & juniper in a fractionated coconut oil carrier. The cap is adorned with a mother of pearl crescent moon & each bottle contains a small moonstone. If you have any questions, please contact me. Thank you for visiting.
