Pulsatilla

The genus Pulsatilla contains about 40 species of herbaceous perennials native to meadows and prairies of North America, Europe, and Asia. Derived from the Hebrew word for Passover, "pasakh", the common name pasque flower, refers to the Easter (Passover) flowering period, in the spring.[1][2] Common names include pasque flower (or pasqueflower), wind flower, prairie crocus, Easter flower, and meadow anemone. Several species are valued ornamentals because of their finely-dissected leaves, solitary bell-shaped flowers, and plumed seed heads. The showy part of the flower consists of sepals, not petals.

Cultural significance

Pulsatilla nuttalliana (as the synonym P. patens) is the provincial flower of Manitoba, Canada[6] and (as the synonym P. hirsutissima) the state flower of the US state of South Dakota.[7] Pulsatilla vulgaris is the County flower for both Hertfordshire and Cambridgeshire in England.[8] Pulsatilla vernalis is the county flower of Oppland, Norway. The UK has introduced the UK biodiversity action plan to address the 49% decline in wild Pulsatilla species.[1]

Use and toxicity

Pulsatilla is a toxic plant. Misuse can lead to diarrhea, vomiting and convulsions,[9] hypotension, and coma.[10] It has been used as a medicine by Native Americans for centuries. Blackfoot Indians used it to induce abortions and childbirth. Pulsatilla should not be taken during pregnancy nor during lactation.[11]

Extracts of Pulsatilla have been used to treat reproductive problems such as premenstrual syndrome and epididymitis.[11] Additional applications of plant extracts include uses as a sedative and for treating coughs.[11] It is also used in the field of homeopathy.[11]

gollark: That would ruin all my hard work *adding* that many bots! And the community would be lost!
gollark: Well, yes, but mostly I just want to get more role space?
gollark: Not all of them have an integration role.
gollark: 500 bots, actually.
gollark: It's mostly bot roles. Which I can't remove without the hassle of removing and readding each bot, unless there's a better way, which I was asking about (Discord is known for weird poorly documented features).
