Directly from the Farms. Our authentic herbs are grown from high quality seeds and are sourced directly through long-standing relationships with over 300 farms across 22 provinces. Additionally, Tianjiang owns or co-owns 66 farms to ensure quality from seedling through finished product.
Geo-Authentic. Approximately 95% of our raw herbs are geo-authentic, meaning they come from their "Dao Di" or their regions of traditional origins. While we would prefer to source all herbs from their Dao Di regions, herbs from some Dao Di regions are not able to meet our stringent standards for sustainability, water and soil quality, heavy-metal content, or concentrations of active chemical constituents.
