Following COVID-19 infection, a post COVID-19 patient may experience Post COVID-19 Syndrome (PCS). This disorder is significantly important for therapies because it can lower an individuals quality of life following COVID-19 infection. Several treatment approaches, including non-conventional therapies such as herbal medicine, traditional therapy, and nutraceuticals, have been suggested for PCS. This narrative review will thoroughly deliberate the pathogenesis of PCS and several alternative, non-conventional therapy modalities, along with their efficacy and side effects. A literature search using PubMed and ScienceDirect databases, using the keywords “Post COVID-19” AND “Herbal Medicine” OR “nutraceutical” OR “traditional therapy” AND “efficacy” OR “safety” to find relevant studies. Clinical trials examining the effectiveness, safety, and indications of these new treatments are covered in our study. According to our research, these approaches show a lot of promise for being both safe and effective for treating post-COVID-19 syndrome. Therefore, more in-depth research is needed on some different therapy modalities that were not addressed in this study but may present interesting avenues for future post-COVID-19 syndrome treatment.
