This was done in animals, not people. Most findings at this stage never become treatments.
This was only done in lab dishes and in mice, not in people.
The short version
Researchers tested a compound from a plant and found it killed glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary cells in the lab and slowed tumors in mice.
What was studied. Researchers pulled a single compound, called 7-methoxyneochaejasmin A, out of the plant Stellera chamaejasme. They tested it on two kinds of human glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary cells grown in dishes, and then on mice that had glioma tumors.
What they found. The compound slowed the growth of both glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary cell types. The more of it they used, the more the growth slowed. It stopped the cells from dividing and made them die. It worked by flooding the cells with harmful molecules that broke their DNA, and by blocking the cells from repairing that damage. In the mice, the compound slowed tumor growth and lowered a marker that shows how fast cells are dividing.
What this means, and what it doesn't
What it could mean: This points to one possible new direction for a glioma: A tumor that starts in the glial cells, the support cells of the brain and spinal cord. Gliomas are graded 1 to 4 by how fast they tend to grow. See the glossary drug. It also helps explain how the plant compound harms tumor cells. For now it is a lead for researchers to follow, not a treatment.
What it doesn't mean: This does not mean there is a new treatment for people. The work was done in cells in a dish and in mice. It has not been tested in a single person. Many compounds that work in mice do not work in people, or turn out to be unsafe. It is not a cure, and it is not something a doctor can offer you. Do not take this plant or any supplement based on this study.
