Possible Harmful Interaction
The herb garlic
is taken to lower cholesterol, among many other proposed uses.
One of the possible side effects of garlic is an increased tendency to bleed.
Therefore, you should not combine garlic and pentoxifylline except under medical supervision.
The herb ginkgo
has been used to treat Alzheimer's disease and ordinary age-related memory loss, among many other uses.
Ginkgo appears to reduce the ability of platelets (blood-clotting cells) to stick together.
Several case reports suggest that this blood-thinning effect of ginkgo may be associated with an increased risk of serious abnormal bleeding episodes in individuals taking the herb.
Because of these risks, you should not combine ginkgo and pentoxifylline without physician supervision.
