Cut up the herbs and put a few pinches of each herb into the charm bag. Tie it tightly with the cord or yarn. Consecrate and charge the item. After doing this, recite this chant:
"This circle of protection moves with me,
It goes where I go,
It bends where I bend,
It protects me on all sides,
From all things seen and unseen,
So mote it be"
