Rating (out of 5): 1

Calea zacatechichi, also known as "dream herb" or "Mexican dream herb," is a plant traditionally used by the Chontal people of Oaxaca, Mexico. Its traditional uses primarily involve promoting vivid dreams and facilitating dream recall, with some ethnobotanical records indicating its use for divination and mild relaxation. There is little to no traditional or scientific documentation specifically connecting Calea zacatechichi to direct support of the parasympathetic nervous system (PNS), which is responsible for "rest and digest" activities in the body.

Some anecdotal reports and minor ethnopharmacological literature suggest mild sedative properties, which could theoretically support parasympathetic tone by promoting relaxation. However, scientific studies are extremely limited. A few laboratory analyses have identified some active compounds (such as germacranolides and caleicine) with potential CNS effects, but these studies do not demonstrate clear action on the PNS or provide robust clinical evidence.

In summary, the use of Calea zacatechichi for supporting the parasympathetic nervous system is based on traditional use for relaxation and dream enhancement, not on direct scientific validation. The evidence supporting this application is weak and largely anecdotal.
