In the family of gas transmitters, hydrogen sulfide (H 2 S) is yet not adequately researched. Known for its rotten egg smell and adverse effects on the brain, lungs, and kidneys for more than 300 years, the vasorelaxant effects of H 2 S on blood vessel was first observed in 1997. Since then, research continued to explore the possible therapeutic effects of H 2 S in hypertension, inflammation, pancreatitis, different types of shock, diabetes, and heart failure. However, a considerable amount of efforts are yet needed to elucidate the mechanisms involved in the therapeutic effects of H 2 S, such as nitric oxide-dependent or independent vasodilation in hypertension and regression of left ventricular hypertrophy. More than a decade of good repute among researchers, H 2 S research has certain results that need to be clarified or reevaluated. H 2 S produces its response by multiple modes of action, such as opening the ATP-sensitive potassium channel, angiotensin-converting enzyme inhibition, and calcium channel blockade. H 2 S is endogenously produced from two sulfur-containing amino acids L-cysteine and L-methionine by the two enzymes cystathionine γ lyase and cystathionine β synthase. Recently, the third enzyme, 3-mercaptopyruvate sulfur transferase, along with cysteine aminotransferase, which is similar to aspartate aminotransferase, has been found to produce H 2 S in the brain. The H 2 S has interested researchers, and a great deal of information is being generated every year. This review aims to provide an update on the developments in the research of H 2 S in hypertension amid the ambiguity in defining the exact role of H 2 S in hypertension because of insufficient number of research results on this area. This critical review on the role of H 2 S in hypertension will clarify the gray areas and highlight its future prospects.
