What the Science Says
Birch Polypore is a bracket fungus that grows on birch trees and has been used in folk medicine for thousands of years. Early laboratory studies suggest extracts may slow the growth of certain cancer cell lines in a dish, and animal studies show it does not appear to disrupt heart rate or blood pressure at tested doses. There is no human clinical trial data to confirm any health benefit, and effective doses for people are completely unknown.
What It Doesn't Do
No proven cancer treatment — lab results in a dish don't translate to humans. No proven immune-boosting effect in people. No clinical evidence it fights infections, reduces inflammation, or improves any measurable health outcome in humans. Don't trust marketing claims that go beyond what early lab work can actually show.
Evidence-Based Benefits
Oral extracts did not alter blood pressure or heart rate in animal studies.
