The Gate of Life lineage is the oldest official system of herbology in Human history, and by far the most sophisticated. Ayurvedic may be as complex, but the ancient ayurvedic practitioners didn’t write down their observations and their herb formulas. This is why the Chinese system is so important– THEY WROTE EVERYTHING DOWN, from 5000 years ago. Take the Gate of Life course and you will see just how sophisticated this healing modality is; and its accompanying health philosophy is most profound. I’m sure you will agree.
