Rhodiola is one of the primary adaptogens in our formulas Inner Peace and TianChi. Along with schizandra, eluethero, reishi and ashwagandha, it forms the adaptogenic mix that makes our products so powerful. Dr. Gerbarg mentions in her book how the original adaptogenic formula studied in Russia for decades was a mix of rhodiola, shizandra, and eluethero. This is the mix given for decades to all of Russia’s cosmonauts and Olympic athletes. Herbworks has enhanced the effect by adding reishi mushroom and ashwagandha to the mix. http://herbworks.com/rhodiola-and-brain-inflammation/
