Aspirin, ibuprofen (Nurofen) and paracetamol (acetaminophen) are among the most commonly used anti-inflammatory and analgesic agents. These medications are also among the most prescribed in connection with both the treatment and prevention of COVID-19, as well as for the relief of side effects after vaccination (fever, headache). Therefore, it is important to know which herbs to avoid in these moments.
