I'm interested in exploring the range of plant extract products that your factory offers. Specifically, I'd like to know about various categories and formulations you have available. Are there particular extracts that emphasize natural health benefits or unique applications in cosmetics, food, or herbal supplements? Additionally, if you could provide information about the sourcing process and any certifications your products hold, that would be greatly appreciated. Understanding the production methods and quality control measures you employ will help me gauge the potential for future collaboration. Looking forward to your detailed response!
