Information on the Source Plant of Astragalus Extract: Distribution and Growth Environment

Astragalus (Scientific Name: Centella asiatica), also known as “Gotu Kola,” is a common perennial herb belonging to the Apiaceae family. Below is detailed information about the source plant, its distribution, and growth environment:

  1. Plant Description:
    Astragalus exhibits a creeping growth habit, typically growing between 10-30 centimeters tall, with leaves that are round or oval-shaped, somewhat lobed, smooth surface, and clear veins. Its flowering season is generally in summer, producing small purple flowers that cluster at the ends of stems or leaf axils, making it a popular ornamental plant.
  2. Distribution:
    Astragalus is widely distributed across Asia, Africa, and Oceania, thriving primarily in tropical and subtropical areas. In Asia, it is prevalent in countries and regions like India, Sri Lanka, China, and Japan. In Africa, it can be found in areas like Ethiopia and Madagascar. In Oceania, it is mainly located in Australia and New Zealand.
  3. Growth Environment:
    Astragalus prefers to grow in moist, partially shaded, or fully shaded environments, typically found near streams, wetlands, field edges, and on cool, shaded slopes. It shows strong adaptability to different soil types, growing in sandy, clay, and limestone soils but is intolerant of poorly draining soils.
  4. Growth Characteristics:
    Astragalus has a robust growth capability and adaptability, allowing it to reproduce and spread rapidly. It grows using creeping stems, continuously extending through underground stems and new roots above ground, resulting in a dense ground cover. In suitable environments, Astragalus grows quickly, demonstrating strong vitality, and often becomes one of the dominant plants in natural settings.

In summary, Astragalus is a common herbaceous plant widely distributed in tropical and subtropical regions, thriving in moist, partially shaded or fully shaded environments, with strong soil adaptability.
