HERBAL MEDICATIONS AND BLEEDING Many herbal preparations act like anti-platelet and anticoagulant medications THE G’S (Ginkgo, Ginseng, Garlic, Glucosamine, Ginger) Ability to antagonize PAF (Platelet Activating Factor) = potentially increase bleeding Garlic Uses: anti-lipidemic, antimicrobial, anti-asthmatic, anti-inflammatory Components implicated in bleeding: volatile oil and ajoene -ajoene is an unsaturated sulfoxide disulfide that is a component of allicin 4 -allicin: a sulfinyl compound that gives garlic its strong odor and flavor -effect of ajoene on platelets is irreversible: lasts for life of the platelet and potentiates the effect of other platelet inhibitors (e.g. aspirin) -several sulfur containing compounds isolated from garlic have also demonstrated significant inhibition of human platelet aggregation Effect: antiplatelet -garlic oil exerts its effect on the archidonic acid pathway -interrupting the synthesis of thromboxane -stimulating the synthesis of prostacyclin -decreases platelet aggregation and increases bleeding -dose dependent effect -occurs with both dietary garlic and garlic supplements -alliin/allicin inhibit the production and/or release of chemical mediators: platelet activating factor (PAF) and adenosine = decreases platelet function (strongest sources of allicin is natural garlic clove) Ginkgo Uses: prevent decreased cerebral functions and peripheral vascular insufficiency associated with Alzheimer’s disease or age-related dementia Components implicated in bleeding: terpenoids (terpene ginkgolides) -potent antagonists of PAF -long-lasting effects and rapid onset with oral dosing Effect: ginkgo increases prothrombin time and decreases platelet activity -many case reports of severe bleeding episodes with ginkgo use -patients taking warfarin and aspirin are at risk for severe spontaneous bleeding with ginkgo use at recommended doses Ginseng Uses: anti-cancer, slows aging, prevent heart attack, improve digestion, reduce hypertension, strengthen immunity, CNS stimulant Components implicated in bleeding: ginsenosides Effect: inhibit PAF, platelet aggregation, thrombin and thromboplastin -antagonizes the effects of warfarin (decrease effectiveness) -potentiate bleeding when combined with aspirin, NSAIDS, warfarin, heparin Ginger Uses: relive motion and morning sickness, decreases pain and inflammation with arthritis, relieves upset stomach Components implicated in bleeding: pungent principles (gingerol, shogaol, zingerone), volatile oils (bisabolene, zingiberene, zingiberol) and proteolytic enzymes Effect: reduces platelet thromboxane and inhibits platelet aggregation -mixed reports in the literature: effects may be most significant with raw ginger 5 Feverfew Uses: anti-inflammatory (rheumatoid arthritis), Preventive for migraine headache, Muscle soreness Components implicated in bleeding: sesquiterpene lactone, parthenolide Effect: inhibits platelet aggregation Fish Oils Uses: skin disorders, cardioprotection, diabetes, headache, immune support, memory, PMS, ulcerative colitis, many others Components implicated in bleeding: various derivatives of omega-3 Effect: Inhibit ADP-induced platelet aggregation. Increased bleeding time is suggested to be due to either less thromboxane (TXA2) or higher prostacyclin I3 levels (antiaggregatory effects). Contradictory studies about effects on fibrinolysis and vascular plasminogen levels. St. John’s wort Use: manage mild to moderate depression Components implicated in bleeding: hypericin: induces cytochrome P450 liver enzymes Effect: induction reaction of drugs in the liver -reduces anticoagulant effect of warfarin (increases clotting) -decreases the effects of many medications Vitamin E Use: fat soluble vitamin used as a dietary supplement Antioxidant: prevents the oxidations of vitamins A and C; protects polyunsaturated fatty acids in membranes from attack by free radicals; protects RBCs against hemolysis Effect: may alter the effect of vitamin K on clotting factors, increasing hypoprothrombinemic (prothombinopenia) response to warfarin = delayed clotting of blood or spontaneous hemorrhage HERB COMMON USES Echinacea Common cold; cough and bronchitis; wound and burn care; urinary tract infection SOME SIDE EFFECTS AND INTERACTIONS Hepatotoxic, especially when used with other hepatotoxic drugs; may decrease effectiveness of corticosteroids 6 Feverfew Garlic Ginseng Kava-Kava Licorice St. John’s wort Valerian Vitamin E Migraine prophylactic; fever reduction; see above See above Inhibits platelet activity; avoid use with warfarin; 5-15% of users may develop aphthous ulcers or GI tract irritation Potentiates effects of warfarin; May decrease effectiveness of certain HIV protease inhibitor drugs See above Antiplatelet properties; Avoid use with other stimulants: risk for tachycardia and hypertension Anxiolytic Serious risks for hepatotoxicity; potentiates alcohol, benzodiazepines, barbiturates = caution with sedation and general anesthesia Gastric disorders; Glycyrrhizic acid in licorice may cause cough and bronchitis hypertension and hypokalemia; contraindicated with chronic liver disease, renal insufficiency, hypokalemia Depression and anxiety Decreases effectiveness of drugs for HIV: protease inhibitors and non-nucleoside reverse transcriptase inhibitors; induces liver enzymes (altered drug metabolism); prolongs effects of general anesthesia (anecdotal reports) Mild sedative; mild Potentiates effects of barbiturates anxiolytic Antioxidant; CVD Increased bleeding risk with other prevention; wound antiplatelet and anticoagulant medications; healing; fibrocystic may affect thyroid function in otherwise breast syndrome healthy person; may enhance hypertension in hypertensive patients (≥ 400 IU per day) Source: American Society of Anesthesiologists.

Dual antiplatelet therapy with aspirin and a thienopyridine has been shown to reduce cardiac events after coronary stenting. However, many patients and health care providers prematurely discontinue dual antiplatelet therapy, which greatly increases the risk of stent thrombosis, myocardial infarction and death. CONCLUSIONS AND CLINICAL IMPLICATIONS: This advisory stresses the importance of 12 months of dual antiplatelet therapy after placement of a drug-eluting stent and educating patients and health care providers about hazards of premature discontinuation. It also recommends postponing elective surgery for one year, and if surgery cannot be deferred, considering the continuation of aspirin during the perioperative period in high-risk patients with drug-eluting stents.
