Combined use can push blood pressure too high or too low — monitor readings if you take blood pressure medication.
May thin the blood
Watch for: Anticoagulants (warfarin), antiplatelets (aspirin, clopidogrel), and other blood-thinning herbs or supplements (ginkgo, garlic, fish oil, vitamin E)
Combining blood-thinning substances can increase bleeding risk, including before surgery or dental work.
