The COVID-19 pandemic continues to pose a global threat. In response, the use of herbal medicines has gained attention, particularly given the worldwide spread of COVID-19 and the need to safeguard public health. A study conducted across 32 countries revealed that around 24.5% of adults are turning to traditional herbal remedies. [22] This study specifically examines public beliefs, attitudes, and practices related to herbal medicine during the COVID-19 pandemic in Egypt. Understanding Egyptian participants' awareness and beliefs about herbal medicine is particularly significant, as Egypt's awareness level is often reflective of the broader Middle Eastern region. This is due to the widespread reach of Egyptian media across the Middle East, meaning that awareness campaigns in Egypt could have a regional impact.
While many medicinal plants and their formulations have been shown to improve health in various diseases, research on the effectiveness of different plant genera against SARS-CoV-2 is still limited. Therefore, studies on these herbs should be conducted in a detailed and systematic manner. In this study, the questionnaire covered a broad range of topics, including participants' experiences with coronavirus infection, their health beliefs about the virus and herbal medicines, and their general knowledge, attitudes, and practices concerning herbal medicine.
Demographic data from the study showed a higher percentage of female participants, many of whom were married, lived in cities, had graduated from college, and worked in non-medical fields. This suggests that women may have greater concerns about infection, a stronger inclination to care for their health, and a greater interest in sharing and testing their knowledge about herbal medicine. Moreover, women were observed to use herbal medicines more frequently than men, indicating that they might be more knowledgeable about the therapeutic properties of plants and more involved in maintaining their families' health. The study also found a link between education levels and the use of herbal medicine to alleviate COVID-19 symptoms, possibly because gathering information on medicinal herbs often depends on one's education. News coverage and social media have played a role in raising public awareness of COVID-19's severity and consequences. [23] Understanding the causes of diseases is the first step in promoting public education. Public knowledge including how diseases are transmitted, preventive measures, and information on herbal medicine is crucial for combating coronavirus infections, especially since the development of new drugs requires extensive trials and lengthy regulatory processes. [23, 24]
As the pandemic persists, people have increasingly turned to alternative health measures. This has led to a higher demand for products such as vitamins, supplements, and natural remedies like herbs and essential oils. Many have also adopted healthier diets and lifestyles to boost their immunity and protect themselves from the virus.
Herbal medicine has been claimed not only to enhance the immune system against the coronavirus but also to effectively prevent and treat SARS-related diseases. [25] It has also been noted for its ability to relieve cold and flu-like symptoms such as fever, cough, fatigue, sneezing, sore throat, and muscle pain. Additionally, herbal medicine can complement modern medicine, creating synergistic effects in treating SARS-related diseases. [16] As a result, the use of herbal medicine is recommended for both the prevention and complementary treatment of COVID-19.
Nearly 82% of respondents were considered knowledgeable about herbal medicines and had a positive attitude toward them. However, only 49.5% of the study participants used herbal medicine during the pandemic. The study used a specific cutoff point (more than 80%) to classify participants as having satisfactory knowledge about the coronavirus. This contrasts with a previous study that found low acceptance of herbal medicine in Egypt. [26]
Previous research has identified commonly used medicinal herbs such as ginger, lemon, black seed, myrrh, mint, honey, and anise, which are used for both nutritional and medicinal purposes. [27, 28] This highlights the variety of natural formulations that could be considered for combating COVID-19 and other viral infections. A study by Alyami et al. explored the use of herbal products to prevent COVID-19, aligning with the suggestion that herbs can play a crucial role in boosting individual immunity. [29] Other investigations into the effects of various herbal supplements on COVID-19 treatment have found significant benefits from ginger, lemon/orange, vitamin C, honey, black seed, and costus. [30] Several plant-based biochemical components can help alleviate common symptoms of COVID-19, such as fever and cough. [31] Adopting a balanced diet that includes healthy foods and medicinal herbs is an essential step in supporting the immune system and preparing for potential future waves of the virus.
Participants who had previously contracted the coronavirus, had chronic diseases, or had a family member hospitalized due to COVID-19 were particularly concerned about the infection and showed a high level of acceptance for herbal treatments. Those who recognized COVID-19 as a serious threat were also more inclined to use herbal medicine. Increasing public knowledge about the safety of herbal medicine should be a priority to encourage its widespread use. [32]
Many participants reported that their families had suffered from post-COVID-19 syndrome, with cough and depression being the most common symptoms. Depression has been identified as the most prevalent neuropsychiatric disorder following COVID-19. [33] Previous studies have found that about 10% of COVID-19 patients experienced a persistent cough for up to four months after recovery. [34–36]
Most participants adhered to precautionary measures to protect themselves from COVID-19, indicating their awareness of the virus's dangers and their fear of infection. About two-thirds of respondents believed that herd immunity could protect everyone from the coronavirus. People typically become immune after infection or vaccination, reducing the number of infections and the virus's reproduction rate. It has been reported that achieving herd immunity requires that 86% of the population be vaccinated. [37]
There were varying levels of confidence in the vaccine's effectiveness, as reflected in the responses to the question, "How effective do you think the current coronavirus vaccines are?" Here, 42.8% rated the vaccines as highly effective, 46.3% as moderately effective, and 10.9% as having low effectiveness. This highlights the importance of building public trust in COVID-19 vaccines, which can be accomplished by launching advertising campaigns and providing transparent information about the vaccines. [24]
Communities should actively listen to concerns, provide answers to questions, and correct any misinformation. [38] Given that public trust in vaccination is relatively low, successful COVID-19 vaccination programs depend on the belief that available vaccines are safe and effective. [39] Lucia et al. emphasized the need for transparency and addressing safety concerns. Supporting COVID-19 vaccination through public messaging, news releases, and combating misinformation is crucial. [24, 40]
While 37.5% of participants reported that they obtained information about herbal medicine from Ministry of Health guidelines, other studies have shown that social media and scientific articles published in the media were the most common sources of information. [41, 42]
During the COVID-19 pandemic, 60.7% of participants considered using herbal medicine to treat common illnesses. Previous studies have listed commonly used herbal medicines, with ginger, honey, garlic, and perilla being among the most frequently cited. [25] These herbs were mainly used to treat sore throat, cough, nasal congestion, and fever. [25]
It is essential to keep the public and healthcare workers informed about new research and information regarding herbal medicine. Participants with higher education levels were found to be more knowledgeable, likely due to their ability to understand educational messages. Higher educated individuals also tend to access a wider range of information sources about herbal medicine, which may not be as readily available to those with lower education levels.
