Question

a. Chamomile

e. Ginseng
f. Green tea

Answer 1

A, B, C, E, F
The intake of chamomile, garlic, ginkgo, ginseng, and green tea supplements at home should be avoided because each increases the effectiveness of anticoagulation. Individuals should avoid these herbal supplements while taking an anticoagulant because the patient's blood will be sig-nificantly less able to clot, exposing him or her to the risk of a catastrophic injury in the event of a fall or trauma. The use of Hawthorn supplements has not been shown to affect the use of anti-coagulants.
