(Myrrh) is widely recognized for its anti-inflammatory and antimicrobial properties, which are utilized for the treatment of oral ulcers, gingivitis, sinusitis, glomerulonephritis, brucellosis and a variety of skin disorders. The current study aimed to assess whether myrrh modulates itch-associated interleukin (IL)-31 cytokine production and histamine release in stimulated human mast cells (HMC-1). To realize this, molecular biology techniques including real-time quantitiative PCR, western blotting and ELISA were employed. The results indicated that Myrrh successfully suppressed phorbol myristate acetate and calcium ionophore-stimulated mRNA expression, and reduced the production of IL-31 in HMC-1 cells. In addition, myrrh served as a suppressor of extracellular signal-regulated kinase and NF-κB activation, indicating its mechanism in the prevention of HMC-1 cell IL-31 production. Myrrh also prevented the release of histamine in HMC-1 cells. Whilst the present study awaitssupport, the pharmacological actions of myrrh provide new indications as to its potential applicability for itch treatment, which cannot be treated with histamine receptor blockers alone.
