Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Star anise (Illicium verum) is widely recognized for its role in the synthesis of the antiviral drug oseltamivir (Tamiflu), which is used to treat and prevent influenza. The fruit contains shikimic acid, a key precursor in the industrial production of this medication. While star anise itself is not a direct antiviral agent in human medicine, its component shikimic acid is essential to the synthesis of antivirals that are clinically validated.

Traditional medicine systems, particularly in East Asia, have used star anise for its purported antimicrobial and antiviral effects, often as part of herbal mixtures for respiratory infections. However, modern scientific studies have largely focused on its chemical constituents rather than the direct use of the spice as an antiviral treatment. Some in vitro studies indicate star anise extracts may exhibit antiviral activity against certain viruses, but these findings have not translated into robust clinical evidence supporting its use as a standalone antiviral therapy in humans.

In summary, the scientific support for star anise in the context of viral infections is primarily indirect, via its contribution to pharmaceutical synthesis, and limited direct evidence exists for its efficacy when consumed as an herb or spice. Therefore, while there is a scientific basis for its association with antiviral treatment, the direct use of star anise for viral infections is not strongly supported by clinical studies.
