Our most important investment over 15 years continues to be in quality control, assurance, batch testing and analysis.

We believe that when working with natural tonics, focusing on consistency and quality control the priority is a requirement in order to expect any results.

In addition to rigorous quality control checks during manufacturing, we send every batch of our capsules and liquid tonic to external labs for High Performance Liquid Chromatography (HPLC) analysis to check for heavy metals, bacteria and other contaminants.

We also store a sample of every batch for the duration of its circulation, as well as samples of the raw Phellinus that was harvested.

Our commitment to quality assurance and best industry practices allows us to enjoy the timeless natural wonders of Phellinus with modern day scientific precision.
