Jacobaea vulgaris, syn. Senecio jacobaea, is a very common wild flower in the family Asteraceae that is native to northern Eurasia, usually in dry, open places, and has also been widely distributed as a weed elsewhere.
Symphytum is a genus of flowering plants in the borage family, Boraginaceae. There are up to 35 species, known by the common name comfrey. Some species and hybrids, particularly S. officinale, Symphytum grandiflorum, and S. × uplandicum, are used in gardening and herbal medicine. They are not to be confused with Andersonglossum virginianum, known as wild comfrey, another member of the borage family.
Echium plantagineum, commonly known as purple viper's-bugloss or Patterson's curse, is a species of the genus Echium native to western and southern Europe, northern Africa, and southwestern Asia. It has also been introduced to Australia, South Africa and United States, where it is an invasive weed. Due to a high concentration of pyrrolizidine alkaloids, it is poisonous to grazing livestock, especially those with very simple digestive systems, like horses.
Crotalaria is a genus of flowering plants in the family Fabaceae commonly known as rattlepods. The genus includes over 700 species of herbaceous plants and shrubs. Africa is the continent with the majority of Crotalaria species, which are mainly found in damp grassland, especially in floodplains, depressions and along edges of swamps and rivers, but also in deciduous bush land, roadsides and fields. Some species of Crotalaria are grown as ornamentals. The common name rattlepod or rattlebox is derived from the fact that the seeds become loose in the pod as they mature, and rattle when the pod is shaken. The name derives from the Ancient Greek κρόταλον, meaning "castanet", and is the same root as the name for the rattlesnakes (Crotalus).
Borage, also known as starflower, is an annual herb in the flowering plant family Boraginaceae. It is native to the Mediterranean region, and has naturalized in many other locales.
Tussilago farfara, commonly known as coltsfoot, is a plant in the tribe Senecioneae in the family Asteraceae, native to Europe and parts of western and central Asia. The name "tussilago" is derived from the Latin tussis, meaning cough, and ago, meaning to cast or to act on. It has had uses in traditional medicine, but the discovery of toxic pyrrolizidine alkaloids in the plant has resulted in liver health concerns.
Echium vulgare — known as viper's bugloss and blueweed — is a species of flowering plant in the borage family Boraginaceae. It is native to most of Europe and western and central Asia and it occurs as an introduced species in north-eastern North America, south-western South America and the South Island of New Zealand. The plant root was used in ancient times as a treatment for snake or viper bites. If eaten, the plant is toxic to horses and cattle through the accumulation of pyrrolizidine alkaloids in the liver.
Heliotropium is a genus of flowering plants in the heliotrope family, Heliotropiaceae. There are around 325 species in this almost cosmopolitan genus, which are commonly known as heliotropes. It is highly toxic for dogs and cats.
Borage seed oil is derived from the seeds of the plant, Borago officinalis (borage).
Pyrrolizidine alkaloids (PAs), sometimes referred to as necine bases, are a group of naturally occurring alkaloids based on the structure of pyrrolizidine. Pyrrolizidine alkaloids are produced by plants as a defense mechanism against insect herbivores. More than 660 PAs and PA N-oxides have been identified in over 6,000 plants, and about half of them exhibit hepatotoxicity. They are found frequently in plants in the Boraginaceae, Asteraceae, Orchidaceae and Fabaceae families; less frequently in the Convolvulaceae and Poaceae, and in at least one species in the Lamiaceae. It has been estimated that 3% of the world’s flowering plants contain pyrrolizidine alkaloids. Honey can contain pyrrolizidine alkaloids, as can grains, milk, offal and eggs. To date (2011), there is no international regulation of PAs in food, unlike those for herbs and medicines.
Cynoglossum officinale is a herbaceous plant of the family Boraginaceae.
Brachyglottis huntii, commonly called rautini or Chatham Island Christmas tree, is a species of flowering plant in the family Asteraceae. It is found only on the Chatham Islands in New Zealand.
Amsinckia menziesii is a species of plant in the family Boraginaceae, the borage or forget-me-not family.
Ithomiini is a butterfly tribe in the nymphalid subfamily Danainae. It is sometimes referred to as the tribe of clearwing butterflies or glasswing butterflies. Some authors consider the group to be a subfamily (Ithomiinae). These butterflies are exclusively Neotropical, found in humid forests from sea level to 3000 m, from Mexico to Argentina. There are around 370 species in some 40–45 genera.
Cordia myxa, the Assyrian plum, is a mid-sized, deciduous tree in the borage family (Boraginaceae), native to Asia. It produces small, edible fruit and is found in warmer areas across Africa and Asia. Other common names include lasura, laveda, pidar, panugeri, naruvilli, geduri, spistan, burgund dulu wanan and ntege.
Echium pininana, commonly known as the tree echium, pine echium, giant viper's-bugloss, or tower of jewels, is a species of flowering plant in the borage family Boraginaceae. It is endemic to the Canary Islands, where it is restricted to the island of La Palma. Echium pininana is an endangered species, and is listed in Appendix I to, and is therefore protected under, the Convention on the Conservation of European Wildlife and Natural Habitats. The specific epithet pininana is Latin for "small pine", though E. pininana is neither closely related to the pine, nor does it resemble that plant.
Pyrrolizidine alkaloidosis is a disease caused by chronic poisoning found in humans and other animals caused by ingesting poisonous plants which contain the natural chemical compounds known as pyrrolizidine alkaloids. Pyrrolizidine alkaloidosis can result in damage to the liver, kidneys, heart, brain, smooth muscles, lungs, DNA, lesions all over the body, and could be a potential cause of cancer. Pyrrolizidine alkaloidosis is known by many other names such as "Pictou Disease" in Canada and "Winton Disease" in New Zealand. Cereal crops and forage crops can sometimes become polluted with pyrrolizidine-containing seeds, resulting in the alkaloids contaminating flour and other foods, including milk from cows feeding on these plants.
Andersonglossum virginianum, known as southern wild comfrey, is a flowering plant in the borage family native to North America. It is also sometimes called blue houndstongue.
Amabiline is a pyrrolizidine alkaloid first isolated in 1967 from Cynoglossum amabile. It is also found in the seeds and flowers of borage and in borage seed oil.
Echites umbellatus is a flowering climber, belonging to subfamily Apocynoideae of the family Apocynaceae and has the English common name devil's potato. It was first described in 1760 by Dutch botanist, Nikolaus Joseph von Jacquin. The species grows in parts of Florida, Tabasco, Yucatán Peninsula, Belize, Honduras, Cayman Islands, Cuba, Hispaniola, Jamaica, Leeward Islands, Bahamas, Turks and Caicos Islands, and the Colombian islands in the Western Caribbean.
