Overview
Lithospermum Root Powder is derived from the dried roots of Lithospermum erythrorhizon, a perennial herb native to East Asia. Traditionally used in Chinese and Korean medicine, it contains bioactive compounds like shikonin, which impart its distinctive purple-red color and therapeutic properties. The powder is prized for its natural dyeing capabilities and its role in skincare formulations due to its soothing and healing effects. Modern applications extend to cosmetics, where it is incorporated into creams, ointments, and lip products for its anti-inflammatory and antimicrobial benefits. Its use in natural dyeing for textiles and food also highlights its versatility in industrial applications.
Physical and Chemical Properties
Lithospermum Root Powder is characterized by its vibrant purple-red hue, which stems from naphthoquinone pigments like shikonin and acetylshikonin. These compounds are lipophilic, making the powder soluble in oils and alcohol but only sparingly in water. The powder has a fine, granular texture and a mild earthy odor. Its stability is influenced by light and temperature; prolonged exposure to UV light or high heat can degrade its active components. The powder’s density is low, typically ranging between 0.4–0.6 g/cm³, and it exhibits no distinct melting point, as it decomposes when heated rather than liquefying.
Main Applications
In cosmetics, Lithospermum Root Powder is a key ingredient in products targeting acne, eczema, and sensitive skin due to its anti-inflammatory and wound-healing properties. It is commonly found in serums, balms, and natural sunscreen formulations. The pharmaceutical industry utilizes it in topical ointments for burns and minor wounds. Beyond skincare, the powder serves as a natural dye for fabrics, cosmetics, and even food products in some cultures. Its historical use in traditional medicine persists, particularly in East Asia, where it is believed to purify blood and reduce fever. Industrial buyers often source it for its dual functionality as a therapeutic agent and colorant.
Safety and Storage
While Lithospermum Root Powder is generally safe for topical use, allergic reactions may occur in sensitive individuals. Patch testing is recommended before widespread application. Ingestion should be avoided unless under professional supervision, as high doses may cause gastrointestinal discomfort. Proper storage is critical to maintaining its efficacy. The powder should be kept in airtight containers, protected from light, moisture, and temperatures above 25°C (77°F). Suppliers often package it in foil-lined bags or dark glass bottles to extend shelf life, which typically ranges from 1–2 years under optimal conditions.
B2B Procurement Guide
When procuring Lithospermum Root Powder, B2B buyers should prioritize suppliers who provide certificates of analysis (CoA) detailing purity, heavy metal content, and microbial limits. Organic certification is advisable for applications in natural cosmetics or food-grade products. Pricing varies based on extraction method (e.g., cold-pressed vs. solvent-extracted) and shikonin content (higher concentrations command premium prices). Bulk purchases (10+ kg) often qualify for discounts, but buyers should confirm minimum order quantities (MOQs) and lead times. Due to its sensitivity to environmental factors, shipping should include climate-controlled options for international transactions. Reputable suppliers are typically located in China, Korea, and Japan, where the herb is cultivated extensively.
