The therapeutic potential of hydrogen sulphide, especially as an anti-inflammatory drug, represents a multi-billion euro business with many clinical trials in progress. A European study is investigating the sulphide mode of action as a means of assessing its toxic health effects.
Sulphide is gaining attention in the field of biomedical research mainly due to its neuro-modulating properties, which have recently been identified. It is now known that sulphide is produced during metabolism of the amino acid cysteine and has divergent physiological and pathological functions.
