There's something secretive about hot springs.
TEIKOKU Pharmaceutical Co., Ltd. has embarked on uncovering it. After analyzing various hot spring elements and combining several minerals into iron-rich hot spring water, they created a substance by special processing over a designated immersion period and named it
'IFMC. (Integrated Functional Mineral Crystal)', also securing a patent for it. The basic efficacy of this mineral crystal is to promote blood circulation through vasodilation.
