Pulmonary Embolism Support Group
By far the most common form of pulmonary embolism is a thromboembolism, which occurs when a blood clot, generally a venous thrombus, becomes dislodged from its site of formation and embolizes to the arterial blood supply of one of the lungs. Symptoms may include difficulty breathing, pain during breathing, and more rarely circulatory instability and death.

They were probably getting information from one supposedly good site l that shows Green Tea as very high in Vit K. for ONE POUND OF DRIED TEA LEAVES NOT CUPS OF BREWED TEA!!! LOL
Indwen, you're probably looking at that same site.
