Human milk negative to the Arakawa reaction will become gradually positive on the administration of vitamin B. In other words, poisonous human milk will become gradually non-poisonous on the administration of the vitamin B. But the rate of the decrease of the poison in the milk is somewhat slow. Yakriton, the detoxicating hormone of the liver, can also decrease the poison in the Arakawa-negative milk without simultaneous administration of vitamin B. This act of yakriton is, however, very probably through the mobilization of what little vitamin an avitaminotic mother has. So, if a moderate supply of vitamin B is made to such a mother at the same time, then yakriton decreases the poison very rapidly and remarkably. Yakriton has thus the property of mobilizing vitamin B, and it is better to treat such a mother with a moderate amount of vitamin B and a subcutaneous injection of yakriton than with a very rich supply of vitamin B alone.
