Background Information on the Plant Source of Pueraria Root Extract

Pueraria, also known as kudzu, is a common traditional herbal material with substantial application value. Hereā€™s a detailed overview of the source plant, distribution, and growth environment:

  1. Plant Overview:
    Pueraria is a perennial herbaceous plant in the legume family, scientifically named Pueraria lobata (Willd.) Ohwi. It has a well-developed root system resistant to harsh conditions, often found as a wild plant. The stems are sprawling and capable of climbing, sometimes attaching to nearby trees.
  2. Distribution:
    Originally from China, Pueraria is mainly found in the Yangtze River basin, Yellow River basin, and southern China. Itā€™s also present in some East Asian countries like Japan and South Korea, adapting well to various environments.
  3. Growth Environment:
    Pueraria thrives in warm, humid, and well-lit environments, exhibiting strong soil adaptability, though it prefers loose, well-draining sandy loam. It is cold-resistant but sensitive to drought, waterlogged conditions, and saline-alkali soil, typically growing below an elevation of 300 meters in low mountainous, hilly areas, valleys, riverbanks, and riverside regions.
  4. Growth Characteristics:
    Pueraria has a prolonged growth cycle, usually requiring 2-3 years to reach harvestable standards. During its growth, the aboveground parts extend significantly, with stems climbing around surrounding trees or supports, forming dense sprawling plant communities. The underground part comprises a spindle-shaped root rich in starch and active components.

In summary, Pueraria is a highly adaptable wild plant predominantly found in China and certain East Asian nations, favoring warm, humid environments with abundant sunlight and a variety of soil types, although prone to certain environmental sensitivities.
