It is a combustible, colourless, and odourless gas that, in some cases, can be used as a reducing agent. Previously, it was assumed to be physiologically inactive in mammalian cells and would not react with active substrates in biological systems. H2 has recently emerged as a new medicinal gas with a wide range of possible uses and found to have both preventative and therapeutic benefits in a variety of organs, including the brain, heart, pancreas, lungs, and liver. H2 has a role in oxidative stress and has anti-inflammatory and anti-apoptotic properties. It not only acts as a safe and effective illness therapy, but it also causes scientists to reconsider the role and advantages of medicinal gas in the human body [4].

As a medicinal antioxidant, molecular hydrogen has advantageous physicochemical characteristics. It has no charge and is even smaller than molecular oxygen. As a result, it can easily pass through cell membranes and diffuse into cellular organelles including the nucleus and mitochondria. Furthermore, because H2's reactivity is so low, it doesn't react with crucial physiologically relevant ROS involved in cell signaling. Hydrogen does not influence physiology, temperature, blood pressure, pH, or pO2, and has never been known to be hazardous at quantities much above clinically therapeutic doses. When too much H2 is supplied, it is simply exhaled through the lungs .
