Others are related to Dabai.

One argument is that Dabai is a betel nut, and betel nut does have a name called Dabai, whose full name is Bai Hua.

Another way of saying this is the following information:

Dabai is an alias for a plant called Dabai Cao Ding. Millet, the whole grass of Euphorbia Euphorbia in Compositae, is mostly distributed in Qinghai, Sichuan, Guizhou, Yunnan and other places, and has the effects of clearing away heat and toxic materials and treating aphtha and furuncle in children.

The source is Guizhou herbs.

English name Herb of Field Senecio scandens

source

Source of medicinal materials: the whole grass of Senecio scandens in Compositae.

Latin plant and animal mineral name: Senecio scandens.

Harvesting and storage: Harvesting in summer and autumn, washing and fresh use.

The prototype of Senecio scandens is panicum miliaceum, which is 20-40 cm high. Stems erect, branched distally or completely, puberulent or subglabrous. Leaves alternate; The leaves are pinnately divided or undivided, 4-8cm long and 1-3.5cm wide, with 3-5 pairs of lobes, spreading, more or less strip-shaped, with sparse or toothless edges, often swollen auricles at the base and slightly thick and hairless on both sides; The upper leaves are usually strip-shaped Heads, numerous, arranged in umbrellas at the ends of stems and branches; Stems slender, with short bracts; Involucre nearly bell-shaped, 6-8 mm long and 4-5 mm in diameter; The total bract is 15- 18, strip-shaped, with membranous edge, sharp apex and several short bracts at the base; Tongue-shaped flower is about 10, with a small tongue and a length of about 5 mm; Tubular flowers are numerous, yellow, and 5-lobed at the top. Achene, cylindrical, short hair, up to 2.5 mm; ; The crown hair is white and about 3 mm long. Bloom in spring and summer.

Habitat distribution

Ecological environment: Born in hillside wasteland and beside village road.

Distribution of resources: Qinghai, Sichuan, Guizhou and Yunnan.

Chemical constituents contain alkaloids.

toxicity

1. Toxicity to the liver The main toxicity of Senecio Senecio alkaloids is to cause liver lesions, and cows, horses, sheep, pigs, chickens, geese and other foods can all be poisoned to death. Acute poisoning is severe liver injury and necrosis; Chronic poisoning is progressive liver degeneration, even cirrhosis, until ascites, coma and death. In addition to hemorrhagic necrosis of the central lobule of the liver and cytomegalosis of liver cells, the main pathological change may be partial or complete occlusion of the vein of the central lobule of the liver, so it is called hepatic vein occlusion (V.O.D or hepatic vein occlusion disease). It has also been reported that humans will get sick if they eat this plant.

2. Other effects must pay attention to the serious toxicity of these alkaloids to the lungs. They can also damage renal tubules and glomeruli; Intravenous injection can cause hypertension, convulsion, uterine contraction and intestinal relaxation. For the isolated intestinal spasm caused by carbachol in rats and rabbits, Senecio alkaloids and Senecio alkaloids have the strongest antispasmodic effect. Their N- oxides usually lose this anticholinergic effect; The saturation of bipyridine ring can increase this activity. Some alkaloids (winter grass alkaloids, pilocarpine, etc. ) has blocking effect on neuromuscular junction (rats and cats), similar to quaternary ammonium decahydrate, such as enhanced contraction at low concentration or at the initial stage of action; But there are also differences, such as curculigine can not antagonize its inhibitory effect. It has no inhibitory effect on cholinesterase. In addition, because it can cause the enlargement and megakaryosis of rat liver and lung parenchyma cells, it has anti-tumor effect, and it can also cause mutation of lanogaster gene in Drosophila, chromosome breakage in plant and rat cells, fetal malformation in rats and so on. So it is considered to interfere with cell division. In vitro and in vivo, some alkaloids and their metabolites (pyrrole derivatives) belong to strong alkylating agents, so some people think that the toxicity of bipyridine to liver, lung and vascular endothelial cells is related to its alkylation.

To identify the hepatotoxicity caused by these alkaloids, there must be three chemical structures: 1. Senecio alkaloids should have double bonds; Saturated, such as platycodon grandiflorum saponin, has no hepatotoxicity. 2. The primary alcohol group on Senecio scandens base must be esterified, especially after cyclization, so it is toxic. 3. There is at least one branched carbon chain on the side chain of the ester. Senecio alkaloids themselves are not toxic.

Sweet in nature; Gender equality; Poisonous

Function is mainly used for clearing away heat and toxic materials. Main children's aphtha; furuncle

Usage and dosage for external use: appropriate amount, mashed with fresh products or mashed with juice.

Various factions discuss Guizhou herbs: clearing heat and detoxifying. Treat aphtha and furuncle in children. A pigment. Some people also call it "Dabai ointment". Dabai is divided into "imitation porcelain Dabai" and "toughened Dabai"

Imitation porcelain white: light blue when wet, bluish white after drying, pure white, that is, yellow white, depending on the needs of users. Imitation porcelain white is soft and easy to scratch, but it has good brightness and feel, and there is light on the wall from the side. Its brightness can be comparable to that of ceramic tiles. Therefore, it is called "imitation porcelain white".

Tempered white: it is also light blue when wet and bluish white when dry. The gloss and feel of toughened white are slightly worse than that of imitation porcelain white, but the hardness of toughened white with superior hardness can be comparable to that of white ash.

"Dabai"-Canon EF 100-400 mm f/4.5-5.6L is nicknamed USM. Because the lens is white, it is larger than the relative EF 70-200F2.8L. It is usm, hence its name. The lens adopts a rear focus floating mechanism, which ensures high imaging quality in the whole zoom section from 100 to 400 mm and the whole focus range from1.8m (the maximum magnification is 0.2 times at 400 mm) to infinity. When focusing, the fourth group and the sixth group move separately, which can accurately compensate the aberration fluctuation when focusing to a short distance. This is the first EF zoom lens with floating mechanism.

This lens can perform image stabilization (hand shake compensation) through a compensation optical system (second group) that moves parallel to the optical axis. The compensation optical system is driven the same as EF 75-300IS, and two vibration detection gyroscopes are used to measure hand vibration. The effect of image stabilizer is equivalent to two-stage shutter speed. This lens also has an image stabilization mode 2, which allows you to follow photography and easily track moving objects.

At the same time, this is a telephoto zoom L lens with image stabilizer as the main component. Use fluorite and ultra-low dispersion lenses. The floating system ensures high imaging quality in the whole focus range. The image stabilizer of this lens has two modes, which are compatible with EF 1.4X II magnifier and EF 2X II magnifier.
