Curable Disease:
     Rhizome: skin softener; peluruh urine, blood cleanser, appetite enhancer, stopping bleeding. in addition it can be used also in an effort to venereal disease treatment (gonorrhea, urinating blood, the 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. EFFECTS OF BIOLOGY and FARMAKOLOGI Infusa reed rhizome as a diuretic effect, on the basis of increased concentration of electrolytes (Na, K, Cl) male white rat urine. Giving infusa reed roots with a dose of 40, 50, 60, 70 g / kgBB antipyretic effect in guinea pigs. Infusa reed flowers at a concentration of 10% at a dose of 12 ml / antipyretic effect kgBB relatively the same as paracetamol suspension 10% in pigeons. Test Clinic: Dekokta roots of the weeds with a dose of 250-300 g, 2 times morning and evening can be cured 27 cases of 30 patients of acute nephritis. In chronic nephritis, herbaceous weeds can reduce edema and lower blood pressure. Dekokta herbs 250 g in the singular or in combination with the rhizome and leaves of Nelumbo nucifera and leaves could treat Agrimonia pilosa epistaksis (nosebleeds), haemoptysis (coughing up blood), hematuri (urinating blood), menorrhagia, and upper gastrointestinal bleeding. In addition, also reported that dekokta reed roots can be effective for the treatment of acute viral hepatitis in 28 cases; usually used in conjunction with Plantago asiatica, Glechoma longituba and Artemisia capillaris buds. Toxicity: In use by the rules, practically no toxic. Securities that are not dfinginkan: Dizziness, nausea, an increase in curiosity defecating, sometimes occurs in clinical use. Pharmaceutical Technology: Cellulose leaf weeds have a water absorption of the relatively well in the manufacture of tablets by direct printing.

Utilization
PART USED:
Only the root (rhizome) that is used for the treatment

EXAMPLE OF USE IN THE COMMUNITY:

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

Fever due to urinate blood:
1 tablespoon full of reed rhizome, boil with a few pieces about kwe (beligu pulp of half-baked sweets made of dry) in two cups of water until half. This water to drink 2 glasses of 1 day. Urine will be normal and the body temperature down.

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


Composition:
Roots: metabolites that have been found at the root of reed ter.diri from arundoin, fernenol, isoarborinol, silindrin, simiarenol, kampesterol, stigmasterol, ß-sitosterol, skopoletin, skopolin, p-hidroksibenzaladehida, katekol, klorogenat acid, isoklorogenat acid, acid p-kumarat, neoklorogenat acid, acetic acid, oxalic acid, d-malate acid, citric acid, potassium (0.75% of dry weight), a large number of calcium and 5-hidroksitriptamin. From the results of other studies of the roots and leaves found in 5 kinds of flavonoid derivatives are derived 3 ', 4' .7-trihidroksi flavon, 2 ', 3'-dihidroksi kalkon and 6-hydroxy flavanol. A flavonoid derivatives that might include groups flavon, flavonols tersubstitusi on 3-0H, flavanon or isoflavones present in the soluble fraction of extracts etilasetat reed roots. In the soluble extract fraction of the roots of water weeds in groups flavon compounds without free OH group, flavon, flavonols tersubstitusi on 3-0H, flavanon, or isoflavones.
