                                Research has consistently shown that the enzyme bromelain, found in pineapples, can influence blood coagulation by slowing clotting time. This means pineapple can thin the blood, not thicken it, but its effects are complex and depend on concentration and context. Fresh pineapple, and especially its stem, is the source of bromelain, which has been studied for its anti-inflammatory and anti-thrombotic properties.
