Essential oils which inhibit blood clotting

Essential oils which may inhibit blood clotting

Some essential oils may inhibit blood clotting. This means, the blood can become thin and you can be at risk for bleeding out during surgery. Not everyone will need to be overly concerned about knowing this information, but for some, the risks can be fatal.

Those who are at risk

If any of these conditions or situations apply to you, then you are more prone to risks when using blood thinning essential oils:

  • you are on blood thinners, such as coumadin (warfarin)
  • you have hemophilia or other bleeding disorders
  • you are prone to bloody noses
  • you are going to have surgery

In most cases only the method of ingestion is not recommended, and topical use is considered safe. However even inhalation can cause the blood to thin, so caution is warranted.

One example that Essential Oil Safety shares: an 85-year-old woman was admitted to a hospital with acute cardiovascular problems, and was prescribed heparin, followed by warfarin. Some weeks after leaving the hospital she returned, suffering from gross vaginal bleeding and subcutaneous hemorrhaging on various parts of the body. The previous week she had liberally applied a preparation containing menthol and methyl salicylate to her arthritic joints.

Be sure to consult with your health care provider before you use any of these essential oils.
