Ginger can inhibit blood clotting
One Australian study found ginger to be a powerful anti-coagulant even more effective than aspirin, and the National Institutes of Health cautions against consuming ginger while on blood-thinning drugs because of an increased risk of bruising or bleeding. If you have a bleeding disorder or take a blood-thinning medication, you might want to steer clear of ginger.
Ginger can reduce flatulence
If you find yourself a little gassy, sip on ginger tea or chew some peeled raw ginger. You can also add a slice or two to bean dishes, which may reduce your flatulence.
