Overview
Peony root tubers are the underground storage organs of Paeonia lactiflora, a perennial plant native to Asia. Valued in traditional Chinese medicine (TCM) as 'Bai Shao', they contain active compounds like paeoniflorin with anti-inflammatory and analgesic properties. In horticulture, these tubers propagate ornamental peonies prized for their large, fragrant blooms. The dual-use nature drives demand in both herbal and landscaping markets, with China being the primary producer.
Product Features
The tubers exhibit a knobby, brown exterior with white or yellowish inner flesh. High-quality specimens are dense, moisture-rich, and free from rot. They thrive in well-drained soils and require minimal irrigation once established. Medicinally, they're rich in monoterpene glycosides and flavonoids. Ornamental varieties are selected for bloom color (pink, white, red) and petal structure, with some cultivars fetching premium prices.
Main Uses
In TCM, processed tubers treat menstrual disorders, muscle cramps, and liver conditions. Modern research explores applications in neuroprotection and skincare. Decoctions and powdered extracts are common preparations. For landscaping, tubers are planted in autumn for spring blooms. They're ideal for borders, cut flowers, and thematic gardens, with a lifespan exceeding 50 years when properly maintained.
Culture and Development
Peony cultivation dates to the Han Dynasty (206 BCE–220 CE), initially for medicine before ornamental hybridization. The 'Luoyang Peony Festival' in China celebrates its cultural significance. Today, controlled cultivation ensures consistent bioactive content for pharmaceuticals, while open-field growth dominates ornamental production. Sustainable harvesting techniques preserve wild populations in Mongolia and Siberia.
B2B Procurement Guide
Bulk buyers should verify: 1) HPLC test reports for paeoniflorin content (≥1.5% for medicinal grade), 2) phytosanitary certificates for international trade, and 3) cultivation method (wild-simulated vs. farmed). Seasonality matters—autumn-harvested tubers have higher active compound concentrations. Partner with GACP (Good Agricultural and Collection Practices)-certified growers for reliability. MOQs typically start at 100kg for dried slices.
