Green tea is among the most consumed drinks in the world. Due to its possible antiviral, antioxidant, and immune-boosting qualities, green tea, which originated in China, offers several health benefits.

Researchers have recently looked into its effectiveness in managing the COVID-19-causing SARS-CoV-2 virus.  

As a result, you may have heard that drinking green tea can help prevent or treat diseases.

In this article, we’ll discuss the effect of COVID-19 and provide tips for boosting your immune system with green tea.


Let’s get started!

Does Drinking Green Tea Prevent COVID-19?

Green tea has many beneficial polyphenols for human health, including epigallocatechin-3-gallate (EGCG), which fights single-stranded RNA viruses like hepatitis C, Zika, dengue, and flu, among others.

SARS-CoV-2 is a single-stranded RNA virus, just like the illnesses mentioned above. As a result, research into using green tea extracts as a potential treatment for COVID-19 is still ongoing.

According to some studies, green tea extracts may inhibit the SARS-CoV-2 virus’ ability to replicate by harming the spike protein, preventing it from entering human cells, and lowering the total spread of the virus. The earliest stages of infection were when EGCG treatment on the study cells was most successful.


It’s crucial to note that drinking green tea won’t prevent COVID-19 or treat it. Because the majority of studies demonstrating an effect on the SARS-CoV-2 virus used concentrated amounts of single green tea extracts, such as EGCG, that are far higher than those found in a typical green tea bag. Additionally, oral ingestion of EGCG from teas results in poor absorption.

Nevertheless, future human research and testing may lead to the possibility of using green tea extracts for the all-natural treatment of COVID-19.

Is drinking green tea beneficial if you have COVID-19?

Inflammation brought on by a COVID-19 infection is known to come with symptoms like weariness, sore joints, and muscle soreness. The anti-inflammatory benefits of green tea might come in handy. It has been demonstrated to lessen the harmful inflammation linked to COVID-19, potentially reducing these symptoms.

Green tea’s EGCG may also speed up the course of infections by limiting viral activity, albeit this effect has only been documented in test-tube research. 


Although in modest doses, green tea also contains other immune-boosting minerals like iron, selenium, and zinc.

Whatever the case, you might discover that drinking a warm cup of green tea while suffering from a COVID-19 infection is just comforting.

Immune-Boosting Tips

Small levels of immune-boosting micronutrients are present in green tea. So, enjoy your green tea and pay attention to the following tips to strengthen your immune system:

  • Avoid smoking since it weakens your immune system.
  • Engage in regular exercise
  • Increase your consumption of anti-inflammatory foods like fruits and vegetables
  • Aim for 7-9 hours of sound sleep per night.
  • Practice hand hygiene and hand washing


Despite its numerous health benefits, drinking green tea cannot prevent or cure the COVID-19 virus. However, after additional human research and testing, concentrated extracts such as EGCG may potentially be used as a natural treatment. Boosting your immune health may aid in preventing COVID-19, so quit smoking, exercise regularly, get at least 7 hours of sleep per night, and practice good hand hygiene.
