Psalm 51 - “ Purge me with hyssop and I shall be clean - wash me, and I shall be whiter then snow”. Hyssop has been used for many years as a cleansing herb to remove negativity and negative workings. Whether these were sent to you or something you brought upon yourself. This herb is widely used by many Root workers and as one of the main herbs in 7, 13 or 21 day cleansing bath.
Hyssop is also hung in the home to add protection from the evil eye.
