these are the ones which were tried by someone i know very well:

- turnera diffusa (damiana) - sweet flowery taste - smooth on the lungs and very calming to mind and body.
- turnera aphrodisiaca (small leafed form of damiana) - tastes even better and also feels a bit nicer in my
opinion.. using just the flowers even tastes nicer.

- leonurus sibiricus (marihuanilla) - tastes very nice and has a nice calming effect.
- cannabis leaf - tastes a little stronger and has a mild euphoric/calming effect
- heimia salicifolia (sinicuichi) - tastes very strange but nice.. a bit like tea - its effects are also
quite nice.. calming on the body and freshening on the mind

- nepeta cataria (catnip) - tastes very flowery and has a soothing effect
- nymphaea caerulea (blue lotus) - calming with a flowery taste to it.

so far damiana flowers and leonurus sibiricus were my favorites.

any other ideas for which herbs we can use as a pillow for our precious?

Personally if I smoked DMT I would put it on top of Cannabis buds mixed with Diplopterys leafs.

But you could also use any of the smoking herbs on this list of Cannabis Subitutes-

Verbascum blattaria ~ "Moth Mullein"

Canavalia maritima ~ "Baybean"
Sida acuta ~ "Common Wireweed"

Pedicularis densiflora & P. groenlandica ~ "Indian Warrior" & "Elephant's Head"
Passiflora incarnata ~ "Passion Flower"
Sceletium tortuosum ~ "Kanna"
Lactuca virosa ~ "Lettuce Opium"
Nelumbo nucifera & Nymphaea caerulea ~ "Lotus"
