Our UK-based manufacturing partner is certified organic and an industry leader in product safety, testing, quality and research. 

Every one of our tinctures is HerbMark® quality and made in GMP-certified facilities. HerbMark® quality means our manufacturer ensures each tincture is made to pharmaceutical standards to ensure consistent high quality and effectiveness across all of our products.  

Our tinctures regularly undergo pesticide and microbial testing to ensure purity and the highest standards. Our manufacturer conducts routine High-Performance Liquid Chromotography (HPLC) analysis, which is used to detect a specific phytochemical or range of phytochemical compounds within a herb. This is to ensure levels of active constituents.
