Background

Bianxucao ÈqÐî²Ý Chinese Name (pinyin): Bianxu

Chinese Name  :

Common Name  :Prostrate Knotweed

Specific Name  : Herba polygoni avicularis

Scientific Name:
Collection  : The drug is collected in summer, when the leaves are growing luxuriantly, remove from roots and foreign matter and dried in the sun.

Description  : Stems cylindrical and somewhat flattened branched, 15 - 40cm long, 2 - 3mm in diameter. Externally greyish green or brownished red with fine and slightly prominent longitudinal striations, nodes slightly swollen with pale brown membranous stipulate sheaths, internodes about 3cm long, texture hard, easily broken, fracture with a white pith. Leaves alternate, almost sessile or short petioled, lamina frequently fallen off, crumpled or broken when whole, lanceolate. Mergins entire, both surfaces brownish-green or greyish green, odorless taste slightly bitter.

Identification  : 1.Powder: Greyish green, the epidermal cells on both surfaces of leaf with almost straight anticlinal periclinal walls. Stomata, anisocytic with 3 subsidiary cells. The transverse view of the mesophyll showing isobilateral parenchymatous cells containing clusters of calcium oxalate, 18 - 43µm in diameter.2.To 5g of the powder add 100ml of 70% ethanol of 5ml of hydrochloric acid, extract under reflux for 3 hours, filter, use filtratre as the test solution. Dissolve quercitrin CRS in methanol to produce a solution containing 0.5mg per ml use as the reference solution. Carry out the method for thin layer chromatography (Appendix Vl B) using silica gel H containing sodium carboxymethyl cellulose as the coating substance and a mixture of toluene-ethyl acetate-formic acid (5:2:1) as the mobile phase. Apply separately 5µl of test solution and 1µl of the reference solution to the plate. After developing and removal of the plate, dry it in the air, spray with 1% aluminum trichloride solution. Examine under ultra-violet light (365nm). The fluorescent spot in the chromatogram obtained from the test solution correspond in color and position in the spot in the chromatogram obtained from the reference solution.

Processing  : Eliminate foreign matter, wash, cut into section and dry.

Action  : To relieve dysuria, to kill parasites and to alleviate itching.

Indication  : urinary tract infection with difficult painful urination, passage of scanty reddened urine and dribbling of urine after urination; eczema; vulval itching with leukorrhea

Precautions  :

Dosage  : 9 to 15 g; for external use, appropriate quantity to be decocted for irrigation.

Storage  : Preserve in a dry place.
