Introduction to the Source Plant, Distribution, and Growth Environment
Polygonum multiflorum is a perennial climbing plant belonging to the Polygonaceae family. It is native to central and southern China but is also found in other parts of Asia. The plant thrives in mountainous regions with well-drained soils and moderate sunlight [6]. Its vines can grow several meters long, and its roots are tuberous which are harvested for medicinal use. The plant prefers humid environments.
Harvesting, Processing, and Storage
The roots of Polygonum multiflorum are typically harvested in the autumn after several years of growth. The harvested roots are then cleaned, dried, and processed, often involving steaming with black beans to reduce toxicity and enhance its therapeutic properties [7]. Proper processing is essential to decrease potential side effects. The processed Polygoni Multiflori Radix should be stored in a well-ventilated, dry place, away from direct sunlight, to maintain its quality and efficacy [8].
