PROCESS & QUALITY
Process & Quality
Controlled at Every Stage,
Consistent in Every Batch
From raw material inspection to processing, quality verification
and final packing, each stage is managed under defined
procedures to support consistent product quality.
OUR APPROACH
Quality Control at Every Stage
A structured process to ensure stable quality from raw material to finished products.
Tibetan Cultivation &
Harvesting
Grown and harvested in high-altitude areas of Tibet, China, with abundant sunlight and cool mountain growing conditions.
Cleaning &
Initial Sorting

Nine-Steaming &
Nine-Sun-Drying
Nine repeated steaming and sun-drying cycles gradually develop the characteristic dark color, soft texture and consistent product quality.
Sorting &
Grading
After drying, the products are carefully sorted and graded again according to appearance, condition and agreed specifications.
Product Finishing
Qualified material is prepared into the required finished-product format according to product specifications and customer needs.
Packaging & Labeling
Finished products are packed in bulk, retail or private-label formats according to confirmed packaging and labeling requirements.
OUR PROCESSING METHOD
Traditional Processing,
Standardized Execution
Our Polygonatum Sibiricum is sourced from high-altitude cultivation areas in Tibet, where abundant sunlight and cool growing conditions contribute to its naturally rich character. After harvest, the rhizomes undergo the traditional Nine-Steaming and Nine-Sun-Drying process, with careful control of moisture, color, texture and handling at each stage to achieve a consistent finished product.
Repeated
Processing
Nine cycles of steaming and sun-drying.
Controlled
Handling
Careful control of time, temperature and drying condition.
Consistent
Finished Appearance
Develops characteristic dark color and soft, supple texture.
