Taraxacum officinale, the dandelion or common dandelion, [6] is a herbaceous perennial flowering plant in the daisy family, Asteraceae.

Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4. This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4). It is a conjugate base of oxalic acid.
Oca is fairly high in oxalates, concentrated in the skin. [15] Significant variation in oxalate concentration exists among varieties, and this variation distinguishes two oca use-categories recognized by Andean farmers. [2] One use category, sour oca, contains cultivars with high oxalic acid levels. [2]
“High-fiber foods such as fruits, veggies, whole grains and legumes can support a healthy gallbladder by aiding in digestion and the prevention of gallstone formation,” says Carly Hart, RD, LD ...
Some foods have high quantities of calcium oxalates and can produce sores and numbing on ingestion and may even be fatal. Cultural groups with diets that depend highly on fruits and vegetables high in calcium oxalate, such as those in Micronesia , reduce the level of it by boiling and cooking them.
Dandelions are thought to have evolved about 30 million years ago in Eurasia. [35] Fossil seeds of Taraxacum tanaiticum have been recorded from the Pliocene of southern Belarus. [36] Dandelions have been used by humans for food and as an herb for much of recorded history.
Weeds [ edit ] Halogeton glomeratus is considered a noxious weed in most regions of the United States; [ 2 ] a particular difficulty with H. glomeratus is that it is poisonous to sheep, and possibly to cattle, due to the high concentration of sodium oxalate in the dry plant. [ 3 ]
Taraxacum californicum, also known as the California dandelion, [1] is an endangered species of dandelion endemic to the San Bernardino Mountains of California. It grows in mountain meadows. [2] Taraxacum californicum is a small perennial wildflower which resembles its close relative, the widespread weed known as the common dandelion (T ...
