Moutan Cortex

Updated: 2026-08-05

Overview

Tree Peony Bark, known as Moutan Cortex in Latin, is derived from the root bark of Paeonia suffruticosa, a plant native to China. It has been used for centuries in traditional Chinese medicine (TCM) for its cooling and blood-activating properties. The bark is harvested, dried, and processed into flakes or powder for medicinal use. In TCM, Tree Peony Bark is classified as a 'heat-clearing' herb, often prescribed to treat conditions like fever, inflammation, and skin disorders. Its bioactive compounds, including paeonol and paeoniflorin, contribute to its therapeutic effects. Modern research continues to explore its potential in treating cardiovascular and inflammatory diseases.

Physical and Chemical Properties

Tree Peony Bark typically appears as brownish-yellow or reddish-brown flakes or powder. It is soluble in hot water and alcohol, making it suitable for decoctions and tinctures. The bark contains several bioactive compounds, with paeonol being the most studied for its anti-inflammatory and antioxidant effects. The bark’s chemical composition varies depending on the growing conditions and processing methods. Key components include monoterpene glycosides, tannins, and flavonoids. These compounds are responsible for its cooling and blood-circulating properties, which are central to its use in TCM.

Main Applications

Tree Peony Bark is primarily used in traditional Chinese medicine to clear heat, cool blood, and promote blood circulation. It is commonly prescribed for conditions such as fever, night sweats, and menstrual disorders. The bark is also used in herbal formulas to treat skin conditions like eczema and psoriasis. Beyond TCM, Tree Peony Bark is incorporated into modern herbal supplements and skincare products. Its anti-inflammatory properties make it a popular ingredient in creams and serums aimed at reducing redness and irritation. Research is ongoing into its potential applications in treating cardiovascular diseases and diabetes.

Safety and Storage

Tree Peony Bark is generally safe when used as directed, but it should be avoided during pregnancy due to its potential to stimulate blood circulation. Always consult a healthcare provider before using it, especially if you are on medication or have underlying health conditions. Proper storage is essential to maintain the bark’s efficacy. It should be kept in a cool, dry place, away from direct sunlight and moisture. Sealed containers are recommended to prevent contamination and preserve its bioactive compounds. Suppliers should provide lab test reports to ensure purity and quality.

B2B Procurement Guide

When procuring Tree Peony Bark for B2B purposes, prioritize suppliers who offer quality certifications and lab test reports. The price varies based on quality, ranging from approximately $10 to $50 per kilogram. Organic and wild-harvested varieties may command higher prices. Key procurement considerations include the bark’s origin, processing methods, and storage conditions. Ensure the supplier adheres to Good Manufacturing Practices (GMP) and provides detailed product specifications. Bulk buyers should negotiate contracts that include quality assurance clauses and delivery timelines to meet production needs.
