Heliotropium
''Heliotropium'' is a genus of flowering plants traditionally included in the family Boraginaceae ''s.l.'', but placed in the family Heliotropiaceae within the Boraginales order, by the Boraginales Working Group.. There are around 325 species in this almost cosmopolitan genus, which are commonly known as heliotropes. They are highly toxic to dogs and cats, as well as to humans. Etymology The name "heliotrope" derives from the old idea that the inflorescences of these plants turned their rows of flowers to the Sun.Chittenden, Fred J. Ed., Royal Horticultural Society Dictionary of Gardening, Oxford 1951 Ἥλιος (''helios'') is Greek for "Sun", τρέπειν (''trepein'') means "to turn". The Middle English name "turnsole" has the same meaning. A Classical myth, told in Ovid's ''Metamorphoses'', imagines that the water nymph Clytie, in love with the sun god Helios, was scorned by him.

Garden Heliotrope
''Heliotropium arborescens'', the garden heliotrope or just heliotrope, is a species of flowering plant in the borage family Boraginaceae, native to Bolivia, Colombia, and Peru. Common names also include cherry pie and common heliotrope. It is an economically damaging invasive species in Australia. Description Growing to tall and broad, it is a bushy, evergreen, short-lived shrub with dense clusters of bright purple flowers, notable for their intense, rather vanilla-like fragrance. Like many borage plants, the vanilla flower also contains poisonous pyrrolizidine alkaloids in addition to the fragrances. Cultivation As a perennial, it is hardy in zones 10 to 11, and requires wintering indoors in zones 9 or colder. It is hardy down to about . It can also be grown as a half-hardy annual (grown from seed under glass and planted out after all danger of frost has passed) in those areas. Alternatively soft-wood cuttings may be taken in summer. During the Victorian era in England thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clytie (Oceanid)
Clytie (; ) or Clytia (; ) is a water nymph, daughter of the Titans Oceanus and Tethys (mythology), Tethys in Greek mythology. She is thus one of the 3,000 Oceanid nymphs, and sister to the 3,000 River gods (Greek mythology), river-gods. According to the myth, Clytie loved the sun-god Helios in vain, but he left her for another woman, the princess Leucothoe (daughter of Orchamus), Leucothoe, under the influence of Aphrodite, the goddess of love. In anger and bitterness, she revealed their affair to the girl's father, indirectly causing her doom as the king Premature burial, buried her alive. This failed to win Helios back to her, and she was left lovingly staring at him from the ground; eventually she turned into a Heliotropium, heliotrope, a violet flower that gazes at the Sun each day in its diurnal journey. Clytie's story is mostly known from and fully preserved in Ovid's narrative poem ''Metamorphoses'', though other brief accounts and references to her from other authors su ...

Heliotropium Europaeum
''Heliotropium europaeum'' is a species of heliotrope known by the common names European heliotrope and European turn-sole. It is native to Europe, Asia, and North Africa, but it is widely naturalized elsewhere, such as in Australia and North America. It grows as a roadside weed in some places. This is an annual herb growing from a taproot and reaching maximum heights near 40 centimeters. The stem and oval-shaped leaves are covered in soft hairs. The inflorescences are coiled spikes of white flowers with fuzzy or bristly sepals. Each flower is just a few millimeters wide. The fruit is a bumpy nutlet. Toxicity ''Heliotropium europaeum'' contains pyrrolizidine alkaloids and is poisonous.

Pyrrolizidine Alkaloid
Pyrrolizidine alkaloids (PAs), sometimes referred to as necine bases, are a group of naturally occurring alkaloids based on the structure of pyrrolizidine. Their use dates back centuries and is intertwined with the discovery, understanding, and eventual recognition of their toxicity on humans and animals. History PAs were first discovered in plants in the 19th century, but their toxic effects were not immediately recognized. Instead, many PA-containing plants were traditionally used for medicinal purposes in various cultures around the world. For example, herbs containing PAs were used in traditional Chinese medicine and by Native American tribes for their purported therapeutic properties. 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. In the earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boraginaceae
Boraginaceae, the Borago, borage or forget-me-not family, includes about 2,000 species of shrubs, trees, and herbs in 146 to 154 genus, genera with a worldwide distribution. The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. Under the older Cronquist system, it was included in the Lamiales, but clearly is no more similar to the other families in this order than it is to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae into 11 distinct families: Boraginaceae ''sensu stricto'', Codonaceae, Coldeniaceae, Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have petiole (bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queen (butterfly)
The queen butterfly (''Danaus gilippus'') is a North and South American butterfly in the family Nymphalidae with a wingspan of . It is orange or brown with black wing borders and small white forewing spots on its Dorsum (biology), dorsal wing surface, and reddish ventral wing surface fairly similar to the dorsal surface. The ventral hindwings have black veins and small white spots in a black border. The male has a black androconial scent patch on its dorsal hindwings. It can be found in meadows, fields, marshes, deserts, and at the edges of forests. This species is possibly a close relative to the similarly colored soldier butterfly (or tropical queen, ''Danaus eresimus, D. eresimus''), in any case, it is not close to the plain tiger (''Danaus chrysippus, D. chrysippus'', African queen) as was long believed. There are seven subspecies. Females lay one egg at a time on larval host plants. Larvae use these plants as a food source, whereas adult butterflies feed mainly on nectar fro ...

Helios
In ancient Greek religion and Greek mythology, mythology, Helios (; ; Homeric Greek: ) is the god who personification, personifies the Sun. His name is also Latinized as Helius, and he is often given the epithets Hyperion ("the one above") and Phaethon ("the shining"). Helios is often depicted in art with a radiant crown and driving a horse-drawn chariot through the sky. He was a guardian of oaths and also the god of sight. Though Helios was a relatively minor deity in Classical Greece, his worship grew more prominent in late antiquity thanks to his identification with several major solar divinities of the Roman period, particularly Apollo and Sol (Roman mythology), Sol. The Roman Emperor Julian (emperor), Julian made Helios the central divinity of his short-lived revival of Religion in ancient Rome, traditional Roman religious practices in the 4th century AD. Helios figures prominently in several works of Greek mythology, poetry, and literature, in which he is often described ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hepatotoxicity
Hepatotoxicity (from ''hepatic toxicity'') implies chemical-driven liver damage. Drug-induced liver injury (DILI) is a cause of acute and chronic liver disease caused specifically by medications and the most common reason for a drug to be withdrawn from the market after approval. The liver plays a central role in transforming and clearing chemicals and is susceptible to the toxicity from these agents. Certain medicinal agents, when taken in overdoses (e.g. acetaminophen, paracetamol) and sometimes even when introduced within therapeutic ranges (e.g. halothane), may injure the organ. Other chemical agents, such as those used in laboratories and industries, natural chemicals (e.g., alpha-amanitin), and herbal remedies (two prominent examples being kava, though the causal mechanism is unknown, and comfrey, through pyrrolizidine alkaloid content) can also induce hepatotoxicity. Chemicals that cause liver injury are called hepatotoxins. More than 900 drugs have been implicated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Butterfly
Butterflies are winged insects from the lepidopteran superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage life cycle, and like other holometabolous insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take s ...
