ISO 22586:2022(E)
Introduction

Paeonia lactiflora root, dried root of Paeonia lactiflora Pallas (Fam. Paeoniaceae), has a long history of

use in East Asian countries. There are two kinds of peony root: white peony root and red peony root,

which are used for different therapeutic purposes. White peony root is used to tonify the blood and

preserve the yin, to nourish the liver and assist in the smooth flow of qi, and to regulate the meridians

and ease pain.

White peony root is known as clinically effective for the treatment of blood deficiency and sallow

complexion, menstrual irregularities, spontaneous sweating, night sweating and chronic pain. Different

quality requirements between different countries and regions, different packaging, transportation and

storage conditions can affect the quality of white peony root.

Therefore, the harmonization of requirements of white peony root is required to ensure quality and

safety. As national implementation can differ, national standards bodies can modify the values given in

5.3, 5.4, 5.5 and 5.7 in their national standards. Examples of national and regional values are given in

Annex C.
