Why was a mushroom extract studied in 2014?
The original article described very small early studies of an extract known as AHCC in people with HPV. Small uncontrolled or early-stage studies cannot show reliably that a supplement clears HPV or is an effective treatment. The findings should not be treated as a reason to buy supplements, delay cervical screening or stop clinically recommended follow-up.
What does current HPV care involve?
Most HPV infections clear naturally. There is no established medicine or supplement that directly eliminates HPV infection. Healthcare professionals can treat conditions caused by HPV, such as genital warts or abnormal cervical cell changes, and vaccination can protect against important HPV types but does not treat an existing infection.
What changed since publication?
Screening programmes and vaccination eligibility have developed. Eligible people with a cervix should attend routine NHS screening and any indicated follow-up. A positive HPV result does not mean cancer. See HPV information, cervical health and NHS HPV guidance. This is a historical research article, not a recommendation for AHCC or other supplements.
