Supplemental Anticoagulants

            Dr. Andrew Weil, interestingly mentions a fungus called tree ear mushroom as important to consider for its anticoagulant properties. However, Dr. Weil’s website includes no articles on this fungus. I employed other search engines such as Google with similar lack of result, based on this name. However, upon a search of the Vermont State College Hartness library databases, a Natural Standard article on a fungus was listed for the topic of food sources with anticoagulant properties. This fungus is called Sanghuang, Phellinus linteus in Latin. I do not know if the fungus named by Dr. Weil and this one mentioned in the article by National Standard are the same fungus, nor did the National Standard information sheet on Sanghuang  mention it having anticoagulant properties. National Standard does list the plant as having antiangiogenic properties(2013). I mentioned this plant simply because if a patient favors Chinese medicine it might be an important plant to watch out for when that patient has venipuncture procedures.

            According to Medline Plus, Feverfew is a plant that can have an effect on medications which are changed by the liver, such as warfarin (Coumadin) and medications that slow blood clotting, such as heparin. (2011) Medline also suggests that, taken in combination with other plant materials and foods such as mentioned in this paperm will present a contraindication to the efficacy of these prescription medications. (2011) Medline suggests that no more than 50-100 mg be ingested of an extract daily. Another name for Feverfew is “Bachelor Buttons,” (Medline) which is a common garden plant whose Latin name is Tanacetum parthenium L Shultz-Bip. (Natural Standard) Along with information about its anticoagulant properties, Natural Standard says that the plant can cause a withdrawal syndrome for chronic users (2013). The dried leaves are traditionally what’s used to create any medicinal remedies. (Natural Standard) Also significant is that the plant may cause poor wound healing, prolonged sedation with anesthesia, as well as bleeding, when “used concomitantly.” (National Standard) Feverfew “has been shown to interact with aspirin” and should not be taken together. (National Standard)

            The root Dong quai is used in Southeast Asia to make medicine and is the species known as Angelica sinesis in Latin. Other species of this plant may be substituted but are “not considered interchangeable medicinally.” (Medline) Dong quai is known to cause light sensitivity in the skin, (Mediline) Dong quai should not be taken with Anticoagulant and Antiplatelet drugs, including aspirin, Warfarin and heparin. (Medline) Also other plant materials, which have been mentioned 

in this paper, should be avoided using together. (Medline) In Traditional Chinese medicine Dong quai is used in cream form to be applied to the penis one hour before sex to prevent premature ejaculation, Dong quai is also used for menstruation symptoms and for menopausal symptoms. (Medline) According to Natural Standard, the standard dose is 1 gram of dried plant or 4 grams of raw root and is taken in daily doses of up to 520 mg per dose for adults 100-175lbs. This plant can cause sedation, increased asthma, and can provide competition with oral contraceptives. (Medline) It should be avoided by those with acute viral infections such as influenza and avoided during the menstrual cycle because feverfew causes increased menstrual bleeding. (Medline)
