After the entry of herbal extracts into our respiratory tract, the aroma particles will spread all over the surface of the bronchial branches. When the upper respiratory tract is invaded and infected by the incoming SARS-CoV-2 virus, its spike protein will be inhibited by the extract of Chinese medicine to prevent its binding with the Angiotensin Converting Enzyme 2 (ACE-2) in the human receptor. The virus activity can be effectively inhibited. The cells can be strengthened so that they can resist virus invasion. By doing so, natural and effective antibacterial protection is achieved.
