What are the morphological characteristics of this plant?
Aster auriculatus has leaves that are distinctly auriculate, meaning they possess ear-like lobes at the base that clasp the stem. The foliage is typically lanceolate or oblong in shape with serrated margins and a texture that can range from smooth to slightly hairy. Its flowering heads are composed of numerous small florets arranged in a compact discoid or radiate pattern, often displaying shades of purple or blue. The stems are sturdy and upright, providing support for the terminal clusters of blossoms. This plant's morphological identity is most clearly defined by the unique lobe structure at the leaf base and its characteristic floral arrangement.
What is the geographical distribution of this plant?
This plant is native to the high-altitude regions of the Himalayas, spanning across northern India, Nepal, Bhutan, and parts of southwestern China. It typically thrives in montane environments located at elevations ranging from 2,500 to 4,000 meters above sea level. These populations are often found clinging to rocky slopes, alpine meadows, and subalpine scrublands. The species favors cool, moist climates characterized by significant seasonal changes. Its distribution is strictly limited to these specific temperate mountain ecosystems.
How is this plant cultivated?

According to a study published by "Molecules (Basel, Switzerland)", the natural product auriculatone was first obtained from Aster auriculatus. This compound demonstrated a potent protective effect against APAP-induced hepatotoxicity in HL-7702 cells. Its sulfated derivative, auriculatone sulfate, showed hepatoprotective effects when administered via intragastric pretreatment at 50 mg/kg. This treatment almost completely prevented increases in serum alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, and ATPase. Furthermore, it maintained levels of glutathione, superoxide dismutase, and glutathione peroxidase while suppressing the increase of pro-inflammatory cytokines TNF-α, IL-1β, and IL-6.
The primary pharmacological activities of this plant are shown in the list below.
- hepatoprotective
What medicinal compounds this plant contains?

According to a study published by "Molecules (Basel, Switzerland)", the plant Aster auriculatus contains the natural product auriculatone. This compound was used to develop auriculatone sulfate, which is a sulfated derivative of auriculatone. When administered to mice at 50 mg/kg, this derivative helped prevent increases in serum alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, and ATPase. The treatment also maintained hepatic malondialdehyde and the activities of glutathione, superoxide dismutase, and glutathione peroxidase at normal levels. Additionally, it suppressed the increase of pro-inflammatory cytokines TNF-α, IL-1β, and IL-6.

The plant contains bioactive compounds that help prevent or repair significant liver tissue damage. These properties make it a subject of interest for managing complex human liver disease.
According to a study published by "Molecules (Basel, Switzerland)", the natural product auriculatone was first obtained from Aster auriculatus and demonstrated a protective effect against APAP-induced hepatotoxicity in HL-7702 cells. Its derivative, auriculatone sulfate, was tested at a dosage of 50 mg/kg to treat APAP-induced liver injury (AILI). This treatment almost completely prevented increases in serum alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, and ATPase. The substance also retained levels of hepatic malondialdehyde, glutathione, superoxide dismutase, and glutathione peroxidase at normal levels. Furthermore, it suppressed the increase of pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 levels in the mouse liver. These findings suggest it may be an effective agent for AILI and other forms of human liver disease.
The main health conditions this plant is used for are shown in the list below.
