Summary:PURPOSE:To provide an immune-activating agent containing a substance extracted from a Gracilaria alga with an aqueous solvent as an ingredient, activating an immunological ability by its phagocytic cell-activating action, and having extremely high safety. CONSTITUTION:An immune-activating agent contains as an active ingredient a substance obtained by extracting an alga belonging to the genus Gracilaria (preferably Gracilaria verrucosa) with an aqueous solvent (preferably water). The active ingredient is preferably obtained by washing the alga with water, drying the washed alga, grinding the dried alga, washing the ground dry powder with methanol, etc., extracting the powder for 30min to 20hrs on a boiling water bath, and further purifying the extract by a method such as precipitation, dialysis, ultrafiltration, etc. The immune-activating agent is preferably orally administered at a dose of 1-300mg/kg of an adult once to twice a day.
