Colloidal Platinum in Hydrogen-Rich Water Exhibits Radical-Scavenging Activity and Improves Blood Fluidity
Scientists compared the antioxidant activity (the ability to remove free radicals) and the effect on blood fluidity of three different water mixtures:
  1. Regular water with dissolved colloidal platinum (tiny particles of the element platinum)
  2. Hydrogen rich water
  3. Hydrogen rich water with dissolved colloidal platinum

They found that hydrogen rich water with dissolved colloidal platinum had more antioxidant activity and improved blood fluidity more than the other two types of water.  These tests were conducted in vitro, meaning in test tubes rather than in living animals or humans.

Platinum Nanocolloid-supplemented Hydrogen-dissolved Water Inhibits Growth of Human Tongue Carcinoma Cells Preferentially Over Normal Cells
Scientists at the University of Hiroshima in Japan combined hydrogen-dissolved water (the same as hydrogen-rich water) with platinum nanocolloid.  Platinum nanocolloid is a solution of water with tiny nanoparticles of the element platinum dispersed throughout it.  They tested the effects of this combination in vitro (in test tubes or a petri dish, not in living subjects.)  They compared the effects to those of three other water solutions: normal purified water, platinum nanocolloid solution alone, and hydrogen rich water alone.

They tested these solutions on skin cancer cells from the human tongue grown in a laboratory cell culture and also on normal human tongue cells.  They found that the solution that contained both hydrogen and platinum was most effective at slowing the growth and formation of cancer cells, while the other solutions had little or no effect.  The growth of normal tongue cells was not affected by any of the solutions.  They concluded that hydrogen water with platinum "is expected to become a useful tool for clinical application to anti-cancer therapy..."

Based on previous studies, the scientists suspected that the anti-cancer effect of the combination of hydrogen rich water plus platinum is due to antioxidant activity.  They used a test called a DPPH-radical scavenging assay to test this.  DPPH is a powder composed of free radical molecules.  They mixed it with the the different solutions, and measured how much each one decreased the free radicals.  They found that both the platinum nanocolloid solution and hydrogen rich water plus platinum decreased the radicals after 10 minutes.  However, the combination of both hydrogen and platinum accelerated the scavenging activity to show a dramatic decrease after only 30 seconds.
