Cactus flowers

Passiflora incarnata

Simply one of the best remedies for insomnia that I know of, Passiflora contains some interesting alkaloids, specifically harmalines, also found in syrian rue (Peganum harmala) and Banisteriopsis spp. (an ingredients in ayahuasca). While Passiflora is generally a safe herb to take, I recommend caution with people on MAO-inhibitors and similar medications.

Cruciferae spp.

Papaver spp.

Mallow, Malva sylvestris(?)

Horsetail, Equisetum hymenale(?)
