Perilla seed is an incredible source of polyphenols, rosmarinic acid, luteolin and other beneficial compounds. This herb has been used to sustain healthy respiratory and immune function for centuries. Studies using animal models have shown that Perilla extract helps balance Th2 cytokines, as well as eosinophil and mast cell activity. This extract supports healthy mucosal immune responses to environmental factors and enriches GI mucosal tissue's cytokine homeostasis.
