FAQ for OEM buyers

Q. Is Paeonia Lactiflora Root Extract globally accepted for cosmetic use?

Yes, Paeonia Lactiflora Root Extract is listed in EU CosIng with skin-conditioning function and is acceptable for cosmetic use in Japan, EU, US, China, and Korea. In Japan it is also a Kampo crude drug (Shakuyaku) regulated under the JP Pharmacopoeia for medicinal use; cosmetic-grade and pharmacopoeia-grade extracts are different specifications.

Q. What is the canonical 'Tōki-shakuyaku' pairing in Japanese skincare narrative?

Tōki (Angelica acutiloba root) and shakuyaku (Paeonia lactiflora root) are paired as the two key crude drugs of the Tōki-shakuyaku-san Kampo formulation traditionally for women's wellness. In skincare positioning, pairing these two ingredients invokes that Kampo-heritage narrative recognizable to the Japanese market.

Q. What functional markers are used for Paeonia lactiflora root extract?

Paeoniflorin is the primary monoterpene glucoside marker for Paeonia lactiflora root and is commonly used for standardization (often 0.5-2% in concentrated extracts). Paeoniflorin content is the typical COA spec for cosmetic-grade material.

Q. What is the difference between Paeonia lactiflora and Paeonia suffruticosa for cosmetic use?

Paeonia lactiflora (shakuyaku, herbaceous peony) uses the root, while Paeonia suffruticosa (botan, tree peony) uses the root bark — they are distinct INCIs and distinct Kampo crude drugs (shakuyaku vs. bokutanpi). Specify which species and plant part on supplier specs to avoid substitution.
