Chinese Yam Dioscorea opposita
Chinese yam (Dioscorea opposita), known as Shan Yao, is a versatile TCM tonic valued for its digestive-support and nourishing properties.
Our Grade A Chinese yam is sourced from premium growing regions and precision-sliced to 3–5 mm at our GMP-certified Bozhou facility.
Each batch undergoes purity testing, heavy metal screening, and microbial analysis with a COA provided.
Primary applications include dietary supplements (digestive health powders, capsule formulations), functional foods (soup bases, porridge ingredients, gluten-free flour blends), and nutraceutical ingredients.
As a direct factory exporter, we supply sliced and powdered forms, support custom mesh sizes and private-label packaging, and welcome trial orders with no strict minimum quantity.
