Buyer Decision Guide
Rehmannia is traded as fresh, dried and processed (prepared) root, each with different colour and profile. Confirm which preparation your specification requires before approval.
- Confirm fresh, dried or prepared root
- Compare colour and TLC identity
- Check moisture and ash limits
- Confirm species versus fo-ti substitution
How This Grade Differs
Rehmannia glutinosa root is not the same as Polygonum multiflorum (fo-ti), although the two are frequently grouped in traditional formulas. Confirm genus and preparation state when comparing grades.
Compare these related grades before approval:
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
