It is suitable for brands and laboratories looking for a well-characterized natural antibiotic component with modern, controlled specifications.<\/p>\n<p>Our usnic acid 98% is produced from carefully selected lichen raw materials through extraction, purification and crystallization processes. Each batch is tested for identification, assay, appearance, moisture, ash, heavy metals, solvent residues, pesticide residues and microbiological parameters to ensure safety and batch-to-batch consistency.<\/p>\n<p>Usnic Acid is a broad-spectrum antimicrobial compound that shows strong inhibitory effects on most gram-positive bacteria and can inhibit the growth of <em>Mycobacterium tuberculosis<\/em>. When combined with small amounts of streptomycin, its inhibitory effect on tubercle bacilli can be significantly enhanced while maintaining relatively low toxicity in experimental models.<\/p>\n<p>In addition, usnic acid has shown activity against certain parasites such as <em>Trichomonas vaginalis<\/em>, and animal studies suggest it may promote liver regeneration in rats after partial hepatectomy. Clinically, it has been reported to have potential benefits in malaria and is used topically for trauma, burns, skin diseases, cervical inflammation, nipple fissures and perineal care.<\/p>\n<p>This ingredient can be applied in topical formulations, oral supplements and feed antibiotic-replacement research, depending on regulatory status and safety assessments in each market. Recommended inclusion levels must follow local regulations and toxicological data, and the Green Life Herb technical team can provide basic information for R&amp;D reference.<\/p>\n<p>As a professional manufacturer in Xi\u2019an, Green Life Herb offers stable supply of Usnic Acid 98% and customized specifications.
