Overview
Large Notoginseng Root (Panax notoginseng) is a prized medicinal herb native to Yunnan, China, and has been used in traditional Chinese medicine for centuries. It is renowned for its bioactive compounds, such as saponins, which contribute to its therapeutic effects. The 'large' grade refers to roots with a diameter of 1.5 cm or more, indicating higher maturity and potency. Cultivation requires specific climatic conditions, including high altitude and well-drained soil. The root is typically harvested after 3–5 years of growth, with older roots commanding higher prices due to increased active ingredient concentration.
Physical and Chemical Properties
Large Notoginseng Root exhibits a hard, dense texture with a slightly bitter taste. Its color ranges from brownish-yellow to grayish-brown, depending on processing methods (e.g., sun-dried or oven-dried). The root contains triterpenoid saponins (notoginsenosides), polysaccharides, and flavonoids, which are responsible for its pharmacological activities. Solubility varies by compound; saponins are more soluble in alcohol, while polysaccharides dissolve better in water. The root is stable under dry storage but may degrade if exposed to humidity or high temperatures, leading to mold or reduced potency.
Main Applications
In traditional medicine, Large Notoginseng Root is used to stop bleeding, reduce swelling, and improve blood circulation. It is a key ingredient in Yunnan Baiyao, a famous hemostatic formula. Modern applications include cardiovascular health supplements, wound-healing ointments, and anti-inflammatory formulations. The pharmaceutical industry extracts saponins for capsules and injectables targeting blood disorders. In the food sector, it is added to health tonics and teas. B2B buyers often source it for nutraceutical manufacturing or export to global herbal markets.
Safety and Storage
While generally safe, excessive consumption may cause side effects like dizziness or nausea. Pregnant women and individuals on blood-thinning medications should avoid it. Proper storage is critical: moisture-proof packaging and temperature control below 25°C prevent mold and preserve active compounds. Quality control includes testing for heavy metals, pesticide residues, and microbial contamination. Suppliers should provide lab analysis reports to ensure compliance with international standards like USP or EP.
B2B Procurement Guide
When procuring Large Notoginseng Root, prioritize suppliers from Yunnan for authenticity. Key quality indicators include root size (larger diameters indicate higher saponin content), dryness (moisture <12%), and absence of mold or chemical treatment. Request certificates of analysis (COA) for saponin content (typically 5–12%) and origin traceability. Bulk orders (100+ kg) may qualify for discounts, but negotiate based on seasonal availability. For international shipments, ensure compliance with customs regulations for herbal products.
