Mushroom extract shows promise against stubborn HPV
NCT ID NCT06752083
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a supplement made from shiitake mushrooms (AHCC) can help women clear a long-lasting high-risk HPV infection. Researchers reviewed medical records of 289 women who either took the supplement, got the HPV vaccine, or did both. The goal was to see if the virus became undetectable after 4 to 6 months.
