Considering the importance of COVID-19 disease pandemic, emerged by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), in line with other studies to find appropriate prevention or treatment methods for this virus infection, our study objective was proposing the use of natural derived ingredients as an approach for COVID-19 disease control. Here we reviewed previous studies on natural derived nasal sprays andfound that some known natural derived ingredients have antiviral properties, so their topical use as a nasalspray is effective in reducing the symptoms of respiratory infections. Moreover, such nasal sprays also have thepotential of decreasing viral load, including titer of coronaviruses, in the nasal cavity. It seems that the use ofcarrageenan or other herbal ingredients in the nasal spray may block the SARS-CoV-2 virus from entering thelung cells of an affected person and can also prevent virus transmission to other susceptible persons. Further,noticing what we know about the novel 2019 coronavirus so far, we suggested carrageenan that has an unspecific physical antiviral activity and some other natural derived ingredients, as a choice in coping with SARS-CoV-2 virus infection.
考虑到严重急性呼吸综合征冠状病毒 2(SARS-CoV-2)引发的 COVID-19 疾病大流行的重要性,我们研究的目的是提出使用天然衍生成分作为 COVID-19 疾病控制的一种方法,以寻找针对这种病毒感染的适当预防或治疗方法。在这里,我们回顾了先前关于天然衍生鼻腔喷雾剂的研究,并发现一些已知的天然衍生成分具有抗病毒特性,因此将其局部用作鼻腔喷雾剂可有效减轻呼吸道感染的症状。此外,此类鼻腔喷雾剂还有可能降低鼻腔中的病毒载量,包括冠状病毒滴度。似乎在鼻腔喷雾剂中使用卡拉胶或其他草药成分可以阻止 SARS-CoV-2 病毒进入受感染者的肺部细胞,并且还可以防止病毒传播给其他易感者。此外,鉴于我们目前对新型 2019 冠状病毒的了解,我们建议使用具有非特异性物理抗病毒活性的卡拉胶和其他一些天然衍生成分来应对 SARS-CoV-2 病毒感染。
