yep - aspirin effects mainly the behaviour of platelets - blood cells that are involved in a part of the clotting process - so it doesn't really thin the blood in the conventional sense - more, just makes the platelets less likely to start to stick together
The way in which aspirin works was discovered by the British researcher Sir John Vane about 40 years ago. He showed that aspirin blocks an enzyme called cyclooxygenase. Cyclooxygenase produces a range of hormones known as prostanoids. In the blood, these prostanoids cause platelets to stick together, so blocking cyclooxygenase with aspirin reduces the formation of blood clots. Prostanoids also affect inflamed areas of the body, such as sprains and damaged joints. This is why in the past aspirin was used as a painkiller and anti-inflammatory drug.
