Rosa laevigata root
Overview
Rosa laevigata root, or 金樱根 (Jīn Yīng Gēn), is a traditional Chinese medicinal herb harvested from the root of the Cherokee rose (Rosa laevigata). This perennial plant is native to East Asia and is widely cultivated for its medicinal properties. The root has been used for centuries in herbal medicine due to its astringent, anti-inflammatory, and diuretic effects. In traditional Chinese medicine (TCM), Rosa laevigata root is classified as having sweet and slightly astringent properties. It is often prescribed to treat conditions such as chronic diarrhea, excessive urination, and inflammatory disorders. Modern research has also explored its potential antioxidant and antimicrobial benefits, though further studies are needed to confirm these effects.
Physical and Chemical Properties
Rosa laevigata root typically appears as dried, irregularly shaped slices with a brownish-yellow surface. The root contains bioactive compounds such as tannins, flavonoids, and triterpenoids, which contribute to its therapeutic effects. These compounds are responsible for its astringent and anti-inflammatory properties. The root is partially soluble in water and alcohol, making it suitable for decoctions, tinctures, and powdered supplements. While specific molecular data (e.g., CAS number or molecular formula) is not widely documented for the whole root, its key properties are well-established in herbal medicine literature. Proper storage in a cool, dry environment is essential to preserve its efficacy.
Main Applications
Rosa laevigata root is primarily used in traditional Chinese medicine and herbal supplements. It is commonly included in formulations aimed at treating gastrointestinal issues, such as diarrhea and dysentery, due to its astringent qualities. Additionally, it is used to address urinary conditions like frequent urination or incontinence. Beyond medicinal applications, the root is sometimes incorporated into functional foods and beverages for its purported health benefits. In recent years, it has gained attention in the nutraceutical industry as a natural ingredient for promoting digestive and urinary tract health. However, clinical evidence supporting these uses remains limited.
Safety and Storage
Rosa laevigata root is generally considered safe when used as directed. However, excessive consumption may lead to side effects such as constipation due to its astringent nature. Pregnant or nursing women and individuals with pre-existing medical conditions should consult a healthcare provider before use. Proper storage is critical to maintaining the root's quality. It should be kept in a cool, dry place, protected from moisture and direct sunlight. Suppliers often provide dried root slices or powder in airtight packaging to extend shelf life. Buyers should verify that products are free from contaminants like pesticides and heavy metals through third-party testing reports.
B2B Procurement Guide
For B2B buyers, sourcing high-quality Rosa laevigata root requires attention to several factors. First, prioritize suppliers with certifications such as GMP (Good Manufacturing Practice) or organic accreditation to ensure product safety and authenticity. Request detailed documentation, including certificates of analysis (COA) for heavy metals, pesticides, and microbial contamination. Price ranges vary based on quality, origin, and processing methods. Wholesale prices typically range from $10 to $30 per kilogram. Bulk purchases may qualify for discounts, but buyers should balance cost considerations with quality assurance. Establish long-term relationships with reliable suppliers to secure consistent quality and competitive pricing.
