Rosa roxburghii

Updated: 2026-09-12

Overview

Rosa roxburghii, also called the chestnut rose or burr rose, is a deciduous shrub native to China, Japan, and the Himalayas. It thrives in mountainous regions and is prized for its high vitamin C content, which exceeds that of most citrus fruits. The plant produces distinctive thorny stems and pink or white flowers, followed by edible hips used in traditional remedies and culinary applications. Historically, Rosa roxburghii has been cultivated for both ornamental and functional purposes. Its resilience to cold climates and poor soils makes it a hardy species for agroforestry. Modern research highlights its antioxidant and anti-inflammatory properties, driving demand in health-focused markets.

Key Features

The plant's most notable feature is its exceptionally high vitamin C concentration—up to 20 times that of oranges. Its hips (fruit) are also rich in polyphenols, flavonoids, and superoxide dismutase (SOD), compounds linked to anti-aging and immune support. The thorny stems and serrated leaves serve as natural deterrents against herbivores. Rosa roxburghii hips have a tart, slightly sweet flavor, making them suitable for jams, teas, and nutritional supplements. The plant's adaptability to harsh growing conditions further enhances its commercial viability, particularly in organic farming systems.

Application Areas

In traditional Chinese medicine, Rosa roxburghii is used to treat fatigue, digestive disorders, and cardiovascular issues. Its extracts are incorporated into tonics and skincare products for their antioxidant effects. The food industry values the hips for natural flavoring and functional ingredients in beverages like kombucha and herbal teas. Pharmaceutical companies explore its potential in nutraceuticals, particularly for immune-boosting formulations. Agro-industrial applications include soil erosion control due to the plant's robust root system. Emerging markets in Europe and North America show growing interest in Rosa roxburghii as a superfood ingredient.

Precautions

Handling Rosa roxburghii requires care due to its sharp thorns, which can cause skin punctures. While the hips are generally safe for consumption, excessive intake may lead to gastrointestinal discomfort due to their high acidity. Pregnant women and individuals on blood-thinning medications should consult a doctor before using medicinal preparations. Storage of dried hips or extracts should prioritize cool, dry conditions to preserve bioactive compounds. Suppliers must adhere to hygiene standards during processing to prevent contamination, especially for export-grade products.

B2B Procurement Guide

Bulk buyers should verify suppliers' certifications, such as organic or GMP (Good Manufacturing Practice) compliance, to ensure quality. Key sourcing regions include Guizhou and Sichuan provinces in China, where wild and cultivated varieties are abundant. Purchase contracts should specify moisture content (below 10% for dried hips) and packaging standards to prevent spoilage during transit. Pricing depends on processing methods—freeze-dried extracts command higher prices than sun-dried hips. Seasonal availability (harvest peaks in late autumn) may affect lead times. Importers should account for phytosanitary regulations, particularly for shipments to the EU or USA.
