This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in mice, not in people.
The short version
A plant extract slowed brain tumor growth in mice, not in people.
What was studied. Researchers tested an extract of a plant called Parnassia palustris in mice with brain tumors. 7 mice got the extract by mouth, and 7 got plain salt water instead.
What they found. Mice given the extract had less tumor growth. Their tumors also weighed less than the tumors in the other mice. Under a microscope, the tumor cells looked less crowded and less abnormal. The extract also changed the mix of bacteria in the mice's guts.
What this means, and what it doesn't
What it could mean: This is an early hint that this plant may be worth studying more. It does not change care for people today. No person was treated in this study.
What it doesn't mean: This does not mean the plant treats brain tumors in people. The work was done only in mice, so it sits at the animal stage. That is a long way from everyday care. It is not a promise of a cure. Taking this plant or a supplement is not a treatment.
