Commelina communis

Background

Chinese Name (pinyin): Yazhicao

Chinese Name  :

Common Name  :Common Dayflower herb

Specific Name  : Herba commelinae

Scientific Name:
Collection  : The drug is collected in summer and autumn and dried in the sun.

Description  : Up to 60cm long, yellowish green or yellowish white, relatively smooth. Stems with longitudinal ridges, about 2mm in diameter, frequently branched or with fibrous roots, nodes slightly swollen, internode 3 - 9 cm long, texture soft, fracture medullated in the center. Leaves alternate, frequently crumpled and broken, whole lamina ovate-lanceolate or lanceolate, 3 - 9cm long, 1 - 2.5cm wide, apex acuminate, margins entire, base decurrent, forming membranous sheath and enclosing the stem, veins parallel. Flower often fallen off, involcre spathe-like, cordate, both sides divided, petals crumpled, blue in colour, odour slight and taste weak.

Identification  : Surface view of the leaf: Non-glandular hairs of two types, both bicellular, one type short conical, 45 - 60µm long, walls relatively thick, basal cell about 45µm in diameter, apical cell short pointed, another type clavate, basal cell 45 - 60µm long, walls slightly thick, apical cells relatively long, the apex obtusely rounded, thin walled often fallen off. Needle crystals of calcium oxalate abundant up to 74µm long.

Processing  : Eliminate foreign matter, wash clean, cut into sections and dry in the sun.

Action  : To remove toxic heat, and to cause diuresis.

Indication  : upper respiratory tract infection with high fever and sore throat; edema, acute urinary tract infection with painfull difficult urination; carbuncles and boils

Precautions  :

Dosage  : 15 to 30 g; 60 to 90 g of the fresh herb; appropriate quantity for external use.

Storage  : Preserve in a ventilated dry place, protected from mould.
