It's estimated more than 80% of Americans use some kind of herbal supplement, but those supplements aren't regulated in the same way prescriptions and over-the-counter medications are.
Sometimes a supplement can interact with another medication.
Now scientists and engineers at the Allen Institute for Artificial Intelligence have developed an online tool to help consumers determine if a supplement will interact with another drug they are taking.
The Supp.AI tool has more than 1,900 supplements and 2,700 drugs in the database.
Consumers will see a red/no symbol for potentially dangerous interactions, which means they should consult with a doctor first before taking a supplement.
A green leaf indicates medications and supplements that have no known dangerous interactions.
