Not to familiar with the term saging.

I assume it is smudging with sage.

I have used all manner of plants and saps for smudging.

here is an incomplete list:
Cedar
Mugwort
Copal (sap resin)
Mushroom(called Thunder Smudge)
Bear root
Juniper
Inner Red Willow bark
River sage
Prairie sage or silver sage.
White sage or California sage(least preferred)
Red Wood

Edit:
Sweat-grass
Madrona bark
bitter root
Juniper (sap,resin,pitch)
Cedar (pitch,sap,resin)
Fir tree (sap,resin,pitch) and boughs or needles.

I also see you ask about experiences.
I have many to the mundane to the unexplained.
