Aspirin or acetylsalicylic acid (acetosal) is a drug in the family of salicylates, often used as an analgesic (against minor pains and aches), antipyretic (against fever), and anti-inflammatory. It has also an antiplatelet (“blood-thinning”) effect and is used in long-term low-doses to prevent heart attacks and cancer.
