Tatarian aster

Para qué se usa

• Asma y sibilancias

  Limitada

  Ethanol extracts relaxed guinea-pig airway smooth muscle and showed anti-asthmatic activity in animal models. It appeared in 205 of 218 Chinese prescriptions analysed for cough-variant asthma, but it has not been tested on its own in people.^1,2

• Bronquitis

  Limitada

  In animal studies Zi Wan San (root with other herbs) and root extracts reduced airway inflammation; human evidence is limited to multi-herb Chinese formulas.²

• Infecciones víricas

  Limitada

  A root extract inhibited influenza A, Newcastle disease and herpes simplex viruses in cell culture and improved survival of mice given lethal influenza when given beforehand. Laboratory and animal work only.⁴

• Tos

  Tradicional

  The Chinese Pharmacopoeia (2020) lists it for cough with excessive phlegm, wheezing, chronic cough and coughing up blood. In mice, shionone and epi-friedelanol from the root reduced ammonia-induced coughing and extracts increased phlegm clearance; honey-processed root was more effective than raw. No clinical trials of the herb alone were found.^1,2

• Estreñimiento

  Tradicional

  Older Chinese medical records describe it as relieving constipation and difficult urination; untested.^1,2

• Traditional Chinese Medicine

  Zi wan (紫菀)

  Acrid, bitter and warm, belonging to the Lung channel; used to clear lung qi, calm adverse-rising qi, relieve cough and resolve sputum. The Shennong Bencao Jing says it relieves cough, regulates cold and heat in the chest and calms the five viscera; later materia medica add coughing of blood, pulmonary abscess and children's convulsions. Honey-frying is said to make it better at moistening the lungs and relieving cough.

Compuestos activos

shionone

triterpene used by the Chinese Pharmacopoeia as the quality marker; antitussive and anti-inflammatory in animal studies

astins A–P

chlorinated cyclic pentapeptides from the root; structurally similar to the hepatotoxic fungal toxin cyclochlorotine; at least astins C, F and G are made by the endophytic fungus Cyanodermella asteris living in the plant

triterpenoid saponins

considered expectorant; haemolytic, so crude extracts are unsuitable for injection

quercetin, kaempferol, ferulic acid

identified as antiviral constituents of the aqueous fraction in one study

Historia

Zi wan is recorded in the Shennong Bencao Jing and has been used in Chinese medicine for more than 2,000 years, traditionally processed with honey, vinegar, wine or ginger and today mainly honey- or bran-fried. In 2026 researchers showed that at least some of its signature astin peptides are made not by the plant but by a fungus living inside it.
