Introduction: Although ash has been used for treatment and cleaning among the people since Avicenna, its use for therapeutic purposes is not common in modern medicine. The main ingredient of ash is potassium hydroxide (KOH).Methods: In this paper, the antiviral properties of KOH were studied in vivo and in vitro conditions in mucolytic, alkaline and enveloped viruses that cause respiratory tract disease. For this purpose, a 6-stage study was planned. The physicochemical properties of the highest dose of KOH, whose caustic properties are well known, that can be used orally in humans, and the changes in the structure of mucus were investigated. Then, interactions of KOH with the membrane phospholipid bilayer complex, mucin 5AC, corona viruses spike glycoprotein, TMPRSS2 and human ACE2 (hACE2) receptors, and neuraminidase active site in influenza virus were investigated in silico, and the toxicity and beneficial properties of KOH in cells, both in vitro and in vivo, were evaluated.Results: It has been shown that at the applied doses, KOH has a mucolytic effect and increases the pH of the environment in mucus. It has been shown to prolong life span in cell culture and have no toxicity, and in the in silico study it binds to the hydrophilic part of the cell membrane, corona virus spike glycoprotein, TMPRSS2 hACE2 receptor and neuraminidase active site in influenza virus. Oral use of KOH in the form of a spray in mice had no toxic effects on the mucosa and the inhaler application has a mucolytic effect by decreasing the viscosity of mucus in the respiratory tract.Conclusion: In light of these findings, KOH can be mucolytic, alkaline, and antiviral for enveloped viruses in the respiratory tract. |
