gamma-Aminobutyric acid (GABA) has been reported to play a neurotransmitter in the central nervous system thereby exerting an inhibition in nerve impulse, in turn ameliorating depression; in addition, recent study also reveals the anti-hypertensive effect of GABA in vivo. Edible fungi of the species have been used as traditional Chinese medicine in eastern Asia for several centuries. -fermented products possess a number of functional secondary metabolites, including anti-inflammatory pigments (such as monascin and ankaflavin), monacolins, dimerumic acid, and GABA. Several scientific studies have shown that these secondary metabolites have anti-inflammatory, anti-oxidative, and anti-tumor activities. Moreover, many published reports have shown the efficacy of -fermented products in the prevention or amelioration of some diseases, including hypercholesterolemia, hyperlipidemia, hypertension, diabetes, obesity, Alzheimer's disease, and numerous types of cancer in recent studies. The current article discusses and provides evidence to elucidate the anti-hypertensive benefit of -fermented metabolites, including anti-inflammatory pigments and GABA.
