This is a summary of research so far, not a new result you can act on.
The short version
Researchers gathered up past studies on a compound from ginseng, called Rg3, to see what the science says so far about it and cancer.
What was studied. This was a review of research that other scientists had already published. The authors searched two large research databases for lab studies, animal studies, and studies in people about a ginseng compound called ginsenoside Rg3.
What they found. Across these studies, Rg3 slowed cancer growth in many kinds of tumors. glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary, a brain tumor, was one of them. The body absorbs Rg3 poorly when it is swallowed and clears it fast, so new delivery methods were used to get more of it into tumors. In some studies Rg3 also worked alongside chemotherapy, radiation, and other treatments, and eased some treatment side effects.
What this means, and what it doesn't
What it could mean: Rg3 is an active area of study as a possible partner to standard cancer treatment. Scientists see enough here to keep researching it. It is not a treatment your doctor can give you for a brain tumor right now.
What it doesn't mean: This does not mean Rg3 treats brain tumors in people. It is not a cure, and it is not proof that one is coming. This paper is a summary of where the research stands, not a new result and not a trial. Much of the work behind it was done in the lab and in animals, which is a long way from everyday care. If you are thinking about a ginseng product, talk to your care team first.
