(57) [Summary] [PROBLEMS] To form an anion-rich atmosphere in tissues of a living body when taken through the oral cavity. SOLUTION: The present invention is an electrochemically bioactive fine particle which supplies a negative charge to a living body of animals and plants to express a bioactivity, Electrochemical physiologically active fine particles are fine particles of noble metals such as gold, platinum and palladium, in particular, platinum colloid, The platinum particles in the colloid are single particles of 2 to 3 nm, and the single particles are dispersed in a chain form on the order of 4 to 8 nm. Platinum colloid forms a field rich in anions in the living body and continues to apply a potential to water molecules absorbed by the digestive tract membrane. This property is maintained after the platinum colloid is ingested from the oral cavity, passes through the large intestine and is excreted from the anus, Moreover, the platinum colloid does not stay in the body. |
