Ranunculaceae (/ r ə n ʌ ŋ k j uː ˈ l eɪ s i ˌ aɪ,-s iː ˌ iː /, buttercup or crowfoot family; Latin rānunculus "little frog", from rāna "frog") is a family of over 2,000 known species of flowering plants in 43 genera, [2] distributed worldwide. The largest genera are Ranunculus (600 species), Delphinium (365), Thalictrum (330 ...
When Ranunculus plants are handled, naturally occurring ranunculin is broken down to form protoanemonin, which is known to cause contact dermatitis in humans and care should therefore be exercised in extensive handling of the plants. [20] The toxins are degraded by drying, so hay containing dried buttercups is safe. [21]
This plant, like other buttercups, contains the toxic glycoside ranunculin, which gives it a bitter, acid taste, so cases of poisoning in humans are rare. [9] It is also avoided by livestock when fresh, but when the plant dries the toxin is lost, so hay containing the plant is safe for animal consumption. [ 3 ]

Aleut first nations may have used juice from the plant as a poison, [3] its toxicity arising from the substance protoanemonin. [4] Shasta first nations coincided blooming Ranunculus occidentalis with salmon runs in the summer. [5] The seeds were used to make pinole, a staple food. [6]
Ultraprocessed foods often contain refined carbohydrates and little to no nutrients. Replacing the seed oils in ultraprocessed foods with lard and beef tallow would make them even worse, Gardner adds.
Ranunculus glaberrimus is a herbaceous perennial plant growing to 4–15 centimetres (1 + 1 ⁄ 2 –6 in) tall. The roots are clustered and fleshy. [4] The somewhat thick basal leaves are oval, with long petioles, ranging from entire to having three deep lobes. Cauline leaves have short petioles but are otherwise similar.
