[ ] habitat distribution
Ecological environment: born in hillside, roadsides, waste, grass, forest margins and sparse forest.
Resource distribution: distribution in the country except Xinjiang, Guangdong, Hainan, Guangxi, Yunnan, Tibet and overseas.
[ ] cultivation
Biological characteristics of likes the warm and humid climate, drought, cold or wet. Lax to edaphic requirement, the soil deep, loose and fecund, good drainage of sandy soil or clay soil on the cultivation for good.
Cultivation techniques for seed, root propagation, seedling transplanting method. Seed propagation: early April seeding, seeding or drill, the seeds are uniformly sow, overlying thin soil, a little repression, watering, keep the soil moist bed. After about2-3 weeks seedling. Seedling height12-15cm shift shift. Choose a cloudy day, will order to irrigate show water, digging seedling, according to the spacing30cm× 25cm open point, Anami 12cm,1 strains of each hole planting, soil compaction, watering. 1hm2uses kind of quantity7.5kg. Root propagation: autumn orange leaf or early spring budding, mining for root, root, root of each with2-3 bud, according to the spacing30cm× 25cm open point plant.
Field management of seedlings after planting, if missing lines, should be planted, and1rare excrement. Squaring to pick bud, again1manure or cake. Every half need cultivating.
[ character ] trait distinguishing root irregular long conic, slightly curved, often branched, long 10-20cm, diameter 0.5-2cm, near root head occasionally expanded to 4cm; root head common stem residues and bud scars. Surface gray-brown or dark brown, rough, with vertical grooves and horizontal lenticels, less contorted branches. Qualitative hard, not easy to break, section of brown or white, fibrous.

[ ] the pharmacological effect
1purgative: on isolated ileum of mice of various Radix euphorbiae, products Decoction on isolated ileum have excitatory effects, intestinal peristalsis, intestinal smooth muscle tension. And with the increase of the concentration of processing vinegar, contraction strength seems to strengthen the trend, among them 50%,70% concentration of excitatory effects particularly evident. This product can stimulate the intestines, causing intestinal peristalsis, produce purgative effects. Beijing Euphorbia Root ether extract has a purgative effect, hot water extract on cat play the laxative effect.
2on the smooth muscle function: extract can dilate peripheral vascular, excited pregnancy isolated uterus.
Antibacterial effect of3northeast of Euphorbia ( Euphorbiasp. ) leaf juice in vitro against Staphylococcus aureus and Pseudomonas aeruginosa are inhibited, but remove tannin, antibacterial effects disappear, preparation save days or heating can make the antibacterial effect of reduced or even lost. Experimental results show, the product of Staphylococcus aureus and Pseudomonas aeruginosa showed inhibition.
4diuretic effect to students of Knoxia Decoction concentrate (80g/kg ), feed on mice,2-3hours later, the urine volume increased significantly.
5Euphorbia and licorice combination impact: according to our previous herbal books are documented, Euphorbia and Radix Glycyrrhizae is taboo, genera and eighteen vice column. Animal experiment proves, intraperitoneal injection of mouse Euphorbia, liquorice root ethanol extract, the half lethal dose than when used alone. Decimal, it can be seen that both when the compatibility of Euphorbia toxicity increased, and compatibility of the toxicity of licorice, the greater the. Such as Euphorbia and licorice are immersed in wine, and when giving drug party mixed administration, its toxicity than common dip is small, but still higher than the single use Euphorbia toxic. In mice by oral administration of Euphorbia and licorice decoction also obtained similar results. Euphorbia, liquorice with50% ethanol extract to mice by intraperitoneal injection, licorice LD50 is 12.4± 0.7g/kg,30± 5.5g/kg spurge Euphorbia coadministration with licorice, increased toxicity. Euphorbia Decoction on mice by intraperitoneal injection of LD50 was 4.69 ±0.021g/kg, Euphorbia plus licorice (1:1) by intraperitoneal injection of LD50 was 5.02 ±0.025g/kg, no increase in toxicity.
Rat peritoneal injection of sodium chloride solution caused by experimental ascites, oral decoction or alcohol extract of Euphorbia, have diuresis effect, such as licorice combination, its diuretic and purgative activity was markedly inhibited, licorice dosage is bigger, the opposite is also stronger. Therefore, from the perspective of the treatment of ascites, the combination of both is not suitable. Another report, mice death as the index, think of Euphorbia ( breed without identification ) and licorice decoction no contrary effect. But the dosage size, experimental rats all not dead, still need further testing.
Euphorbia Decoction40%0.5ml gavage, either alone or in combination with Euphorbia licorice, on mice purgative effect without obvious difference.
Isolated small experiment:0.01%-1% liquorice decoction on isolated rabbit intestine is the effect of high concentrations inhibit, but with the concentration of chemical reduction, inhibition is also gradually weakened, and gradually appear slightly excited role; roast Beijing euphorbia Decoction high concentration does not change significantly when the contraction amplitude or slightly lower, at low concentration rises, tension decreased; when combined, with the same dose of single decoction, high concentration, inhibition is enhanced, when the concentration is low, the difference was not significant or slightly inhibited, and licorice is larger than Beijing euphorbia, particularly significant.
The analgesic effect of YSD using a4pharmacological experimental instrument for measuring and recording, electrical stimulation of box. Mouse Ig of licorice root and Radix euphorbiae decoction, have some analgesic effect, and more significantly, while Beijing euphorbia is licorice. When combined with the same dose, the single decoction, when two equivalent, the analgesic effect after single decoction; when the licorice more than the amount of Euphorbia pekinensis, analgesic effect is better than that of single decoction, and the dosage, low dose compared with large dose.
On isolated frog heart function in isolated frog heart experiment: according to Sri Lanka's Strdub isolated frog heart perfusion preparation of isolated frog heart, each of the 5frog heart, divided into 20experimental groups, take the average curve and compared,0.31-5% of Glycyrrhiza uralensis and roast Beijing euphorbia Decoction on isolated frog heart effect of high concentration shows obvious inhibition effect, low concentration, weak or not obvious; when combined, with the same dose of single group comparison, inhibition is enhanced in different degrees, and the concentration is higher and more significant, while the 0.63% is not so obvious.
6other roles in the root bark of70% ethanol extract was injected into the animal, a slight rise of blood pressure, renal volume significantly smaller size, regardless of the dose, diuretic effects are not significant. Healthy adult clothing decoction was also a diuretic effect. Extract on peripheral vascular dilatation effect, can inhibit adrenergic pressor effect. Congeneric plant Euphorbia pekinensis Japanese variants of EuphorbiapekinensisRupr.var.JaponensisMak. aqueous extract on rabbit, guinea pig in vitro and in a contraction uterus. The black sea water extract of Euphorbia EuphorbiaponticaProkh, tinctures and plant powder made of ointment for skin, has obvious stimulation, long-term use can cause redness, burning sensation, vesicles and peeling. Facial skin is more sensitive to. Infusion of weak stimulation. New gallon injection in frog or cat can make asystole in systole. May contain strong heart glucoside.
