Schisandra chinensis is a vine bearing berries that taste of all five basic flavors — sweet, sour, salty, bitter, pungent. Long history in TCM and Russian phytomedicine for vitality, liver protection, and stress resilience. Its lignans (schisandrins) support liver detoxification via Phase I/II enzymes, modulate the HPA axis, and have mild central nervous system effects. Russian Olympic athletes and astronauts used it for stamina and stress; modern Chinese research emphasises hepatoprotection.
