Our study assessed the phytochemical composition and the effects of Salvia balansae flower aqueous extract (FAE) on sexual dysfunction in diabetic rats. Total phenolic and flavonoid content, quantification of phytochemicals by ultrahigh performance liquid chromatography (UHPLC)-electrospray ionization (ESI)-tandem mass spectrometry (MS/MS) method, and in vitro antioxidant capacity of FAE extract were elucidated. For the in vivo study, diabetes was induced by one intraperitoneal injection of streptozotocin (STZ) (40 mg/kg), and treated diabetic rats were given FAE at 200 mg/kg.

To combat the coronaviruses and their novel variants, therapeutic drugs and the development of vaccines that are to be effective throughout human life are urgently needed. The endocannabinoid system (ECS) acts as a modulator in the activation of the microcirculation, immune system, and autonomic nervous system, along with controlling pharmacological functions such as emotional responses, homeostasis, motor functions, cognition, and motivation. The ECS contains endogenous cannabinoids, cannabinoid receptor (CBRs), and enzymes that regulate their biosynthesis, transport, and degradation.
