Aerial florida.

The leaves of this species annually, are presented in petiolated and rosettes at the base, are sessile at the top and very narrow. Inflorescence, paniculiforme, tight and oblong, includes many chapters whose flowers outside ray and white, are arranged in several rows.

Source.

Originally from North America, the plant has experienced a major expansion. It is frequently found on uncultivated land among the rubble, sand gardens and rivers.

Chemical composition.

Gálicos contains tannins, or acid - benzilbenzoico, a small amount of essential oil, and poliínos a cumuleno [741] Some steroids have been identified: estigmastenol, stigmastadienol and ketones for the [742] espinasterol, b - sitosterol [743] and similar derivatives [746] The leaves are rich in a heterósidos flavones: escutelarósido, escutelareína glucuronide (2. 5% in the leaves)

Pharmacological data.

The comments indicate that the Erigeron stimulates smooth muscle (rabbit ileum) and transiently decreases blood pressure (dog, 50mg / kg, aqueous extract, ip) The extract is analgesic and antipyretic. The toxicity is low (D. L. 50 = 5g / kg)

Experiments have been conducted to confirm the properties traditionally attributed to the drug: antidiarreica, anti - inflammatory, diuretic. The trials of acute and subacute have shown no toxicity of the drug criomolida of Erigeron (3 g / kg, 300 and 600 mg / kg / day, rat, per os)

The drug.

Caulinares leaves, scattered or alternate on a stalk covered with rough hairs are pale green ash, so lanceolate linear. Limbo, pointed at the tip, is entirely or partially serrated. The involvement of the bracts are linear, overlapping, almost glabrous, membranous at the edges. Female flowers peripheral ray tubulosas hermaphrodite flowers and plants embedded on a jack plane and almost naked. The microscopic analysis shows warted leaf hairs, fragments of hair silky and Vilan tricolporoideo with pollen exine equinulada. The C. C. F. made with a dye allows quick and a qualitative study of the drug.
