Reed (Alang-alang)

Reed (alang-alang)
(Imperata cylindrica (L.) Beauv.) 

Lagurus cylindricus L. , Imperata arundinacea Cirillo. 



Posture: herb, grass, creeping, 30-180 cm tall. 
Trunk: rhizome, creeping under the soil, forming a single inflorescence stems erect, solid, in its segment rarely hairy. Leaves: single, base close to each other, strands, ribbon-shaped, sharp pointed tip, straight, coarse, hairy rarely, size 12-80 cm. x 35-18 cm. Flowers: composition compound compound grains, rather furl, 6-28 cm long, each branch has 2 grain, 2.5 to 5 cm branch, flower stalks 1-3 mm, gluma 1; tip ciliated, 3-6 veins, Lemma 1 (chaff); broad ovate, short cilia from 1.5 to 2.5 mm. Lemma 2 (husk), elongated, tapering from 0.5 to 2.5 mm.Palea (husks); 0.75 to 2 mm. Stamens: anthers 2.5 to 3.5 mm, yellowish white or purple. Stigma: the stigma of feather-shaped. Fruit: type rice. Seed: shape elliptic, 1 mm long. Flowering time: January to December. Regional distribution, Habitat and Cultivation: In Java grew at a height of up to 2700 m asl, in areas of open or half closed, the marsh; in soil with good aeration, in areas which open out, on the banks of the river; extensive secondary forests; area burned; as a weed in fields, gardens and plantations. This plant can influence the cultivation of other crops, because it needs a relatively high sodium.Multiplication: multiply by itself. Every time the roots are harvested from plants that have been mature. Pale-colored rhizome good, taste sweet and cool. Reed to menuyebabkan decrease soil pH. The amount of decrease in pH and barriers to the process of nitrification showed a positive correlation with the growth of reeds.

NAME SIMPLISIA : Rhizoma Imperatae; reed rhizome 

Roots: metabolites that have been found in reed roots consist of arundoin, fernenol, isoarborinol, silindrin, simiarenol, kampesterol, stigmasterol, ß-sitosterol, scopoletin, skopolin, p-hidroksibenzaladehida, katekol, chlorogenic acid, isoklorogenat acid, p-acid kumarat, neoklorogenat acid, acetic acid, oxalic acid, d-malic acid, citric acid, potassium (0.75% of dry weight), large amounts of calcium and 5-hidroksitriptamin. From the results of other studies on the roots and leaves found in 5 different flavonoid derivatives ie derivatives 3 ', 4' 0.7-trihidroksi flavone, 2 ', 3'-dihydroxy kalkon and 6-hydroxy flavanol. 
A derivative of flavonoids which may include classes flavone, flavonol substituted at the 3-0h, flavanones or isoflavones present in the soluble fraction in ethyl acetate extract of the roots of the weeds. In the fraction of water-soluble extract of the roots of the weeds found flavone class of compounds without the free OH groups, flavonoids, flavonol substituted at the 3-0h, flavanones or isoflavones. 
Curable Disease: 
Rhizome: skin softener; laxative urine, blood cleansers, appetite enhancer, stop the bleeding. 
in addition it can be used also in treatment efforts venereal diseases (gonorrhea, blood urine, lion king), kidney disease, injury, fever, high blood pressure and nerve disease.All parts of plants used as animal feed, paper materials, and for the treatment of ringworm.

BIOLOGICAL EFFECTS OF PHARMACOLOGY infusa and reed rhizome effect as a diuretic, on the basis of increasing concentrations of electrolytes (Na, K, Cl) male white rat urine. Giving infusa reed roots with a dose of 40, 50, 60, 70 g / kg antipyretic effect on the guinea pig. Infusa reed flowers at a concentration of 10% with a dose of 12 ml / kg antipyretic effect of paracetamol suspensions are relatively equal to 10% in pigeons.Clinical test: Dekokta reed roots with dose 250-300 g, 2 times morning and evening to cure 27 cases from 30 patients with acute nephritis. In chronic nephritis, herbaceous weeds can reduce edema and lower blood pressure. Dekokta herbs 250 g in the singular or combined with roots and leaves of Nelumbo nucifera and Agrimonia pilosa leaves to treat epistaxis (nosebleeds), haemoptysis (coughing up blood), hematuri (urinating blood), menorrhagia, and upper gastrointestinal bleeding. In addition it was reported also that Dekokta reed roots can be effective for the treatment of acute viral hepatitis in 28 cases; usually used together with Plantago asiatica, Glechoma longituba and Artemisia capillaris buds. Toxicity: In the use according to the rules, practically not toxic. Securities not dfinginkan: Dizziness, nausea, increased bowel movements curiosity, sometimes occurs in clinical use. Pharmaceutical Technology: Cellulose leaf weeds on the water absorption has a relatively well in the manufacture of tablets by direct compression. 


Only the roots (rhizomes) used for the treatment of 


As a laxative urine: 
49 dried rhizome, cut into pieces and then added with 2 cups of water and boiled until the volume of water to 1 cup, filtered, then taken 2 times a day. 

Fever due to bloody urination: 
1 tablespoon full of reed rhizome, boil with a few pieces of pliers kwe (half-ripe fruit flesh beligu made candied dried) in two glasses of water to live up to half. 
This drink 2 glasses of water a day. 
Urine will be normal and the body temperature down. 

"Zwartwaterkoorts" (Nederland): 
Drinking boiled water as tea alang grass roots.
