Patients not infrequently inquire about the benefit of “natural blood thinners”. Clot Connect has written a document for patients – available here  – discussing the various herbs and dietary supplements that are often called “natural blood thinners”. The blog post discusses many items including garlic, gingko, chocolate, fish oil, vitamin D, vitamin E, etc. The health care professional may want to be familiar with these herbs and supplements and the laboratory and few clinical data behind them, to be able to respond to patients initiating discussion about the potential usefulness of these  products.
