How about Calea zacatechichi aka dream herb?
From wiki:
In Mexico the plant is used as an herbal remedy for dysentery and fever.[3] The Zoque Popoluca people call the plant tam huñi (“bitter gum”) and use it to treat diarrhea and asthma, and the Mixe people know it as poop taam ujts (“white bitter herb”) and use it for stomachache and fever.[4]
The Chontal people of Oaxaca reportedly use the plant, known locally as thle-pela-kano, during divination. Isolated reports describe rituals that involve smoking a plant believed to be this species, drinking it as a tea, and placing it under a pillow to induce divinatory or lucid dreams due to its properties as an oneirogen.[5] Zacatechichi, the former species name, is a Hispanicized form of the Nahuatl word “zacatl chichic” meaning “bitter grass”.[6] Users take the plant to help them remember their dreams;[2] known side effects include nausea and vomiting related to the taste and mild-to-severe allergic reaction.
While quite bitter if brewed in hot water, the bitterness can be considerably masked by brewing with Osmanthus flowers, which have a compatible scent profile.
