We supply multiple available forms for bulk purchase: whole root tuber, root slices, cut segments and milled rehmannia powder. Several commercial grades are offered to match different formulation plans. Every batch is sampled and inspected by independent third-party laboratories. Test coverage includes moisture, foreign matter, heavy metals and microbial limits. Documents such as COA and MSDS can be provided upon request.

This natural botanical raw material fits clean label projects across food and beverage production. It works well for herbal tea blends, botanical ingredient compounding, cereal mixes and custom dry powder compounding. Manufacturers may further slice, crush or mill the root tuber in-house according to their own production workflows.

We maintain stable sensory performance and consistent quality for bulk export orders. Multiple rounds of screening help remove underdeveloped tubers, broken fragments and foreign debris before packing. Standard food-grade packaging is available, and custom private packaging can be arranged for large-volume buyers. Organic grade rehmannia root can also be sourced on request.

Store dried rehmannia root in cool, dry, shaded and ventilated warehouse space. This raw material is sensitive to high humidity and warm surroundings. Keep containers tightly sealed after opening to avoid moisture absorption and mildew.
