Salicylates are also present in flavorings, perfumes, scented toiletries, eucalyptus and some medication (such as aspirin).
Aspirin is a salicylate. Blocking vitamin K is why aspirin can "thin" the blood - it basically keeps blood from coagulating. This is why too much aspirin can cause stomach and intestinal bleeding. Antibiotics can cause bleeding problems from vitamin K deficiencies.
