I so can relate to that and this is go perfect for that, just remember that when you smudge to remove negative energies, you should have your windows open so it can truly clear out!
I honestly don't have like bulk amounts, but I do have quite a bit. We started out with a pound of sage and between what we used and some that I gave away, I took the rest and bagged it up. I do yard sales and sell some then too, I also have cedar chips and some pine resin, just haven't gotten any of them listed yet.
To use to clear negativity, simply light the sage and allow it to burn till the flame is out, then it smokes and you walk thru your home in each room. but make sure the windows are open while doing this so that the negativity has a way out. Can also use to "smudge" one's self by placing it on the floor and standing with your feet on either side so that the smoke comes up and around you.
Please note, when burning sage, ALWAYS use a HEAT PROOF container!!
