This looks across many earlier studies rather than running a new one.
This was only done with cells in dishes and in animals, not in people.
The short version
Plants from a region of Brazil slowed cancer cells in lab tests, but no people were tested.
What was studied. Researchers pulled together Sixty-two published studies on plants from the Brazilian Cerrado. The studies tested extracts and single compounds from more than 40 plant species against cancer cells and in animals.
What they found. 55 of the studies used cancer cells in dishes. 12 used animals, and five did both. The plants most often left fewer cancer cells alive, made cancer cells die, and stopped them from dividing. The cancers studied included glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary, a brain tumor. The review found no trials in people.
What this means, and what it doesn't
What it could mean: For now, this changes nothing about your care. These plants may give scientists leads for new drugs to study later. It does not mean any plant product is safe or helpful for a tumor. Talk with your care team before taking any supplement or herbal product.
What it doesn't mean: This is not a cure, and it is not a treatment you can ask for. The work sits at the earliest stage, in dishes and in animals. No trials in people have tested these plants for cancer. The review also found missing safety and dosing facts. That is a long way from everyday care.
