DRUG NAME: MOA: • Increases production of IL and NK cell activity (immune suppressant) PROPOSED USE: • Marketed to reduce duration of the common cold if started w/in 24 hrs of onset of sx • CV - lowers total cholesterol and LDL cholesterol; may inhibit plt aggregation; reduces SBP and DBP Garlic • CV MOA - inhibits HMGCoA reductase and antioxidant properties DRUG INTERACTIONS: NOTES: immunosuppressant meds • avoid in immune def disorders or autoimmune disorders; ppl taking immunosuppressant meds • URTI prevention: risk ratio 0.78; 10• Unpleasant taste, GI upset, 20% risk reduction; duration not or allergic reactions (eg, rash) affected Echinacea • Demonstrated weak abx/antiviral/antifungal effects ADVERSE EFFECTS: • antimicrobial, antiviral, immuneenhancing - reduces total # of colds, but evidence not strong • Short-term use (eg, 10–14 days) is probs safe • anticlotting meds (warfarin, nausea, hypotension, allergy, ASA) - increases risk of postop bleeding, spinal bleeding epidural hematoma, breath and body odor, contact • protease inhibitors - reduces dermatits w/ raw garlic bioavailability of saquinavir • antineoplastic use being studied Gingko biloba increases blood flow, reduces blood viscosity, promotes vasodilation • CV - enhances tissue perfusion, increases blood flow, reduces viscosity, and promotes vasodilation - mild/mod vascular occlusive disease • dementia and memory - possibly an add-on to conventional dementia therapies (not for prevention) • schizophrenia n/d, HA, GI upset, allergy, anxiety, insomnia, bleeding complications, seizures warfarin, ASA need to monitor INR more frequently if pt wants to begin using any of these while taking warfarin - all can elevate INR need to monitor INR more frequently if pt wants to begin using any of these while taking warfarin - all can elevate INR DRUG NAME: MOA: PROPOSED USE: • improve mental performance and increase energy • cold prevention • lower postprandial glucose Ginseng ADVERSE EFFECTS: DRUG INTERACTIONS: NOTES: • P ginseng - CNS stimulation and htn • vaginal bleeding, mastalgia, and gynecomastia in an adolescent male - case report --> suggests estrogen effect warfarin • nonspecific cancer prevention and • caution w/ alleviating cancer-related fatigue - may immunocompromised, ppl benefit when combo w/ chemo in taking immune stimulants, ppl certian types of cancers w/ autoimmune disorders Glucosamine/chondroitin • glucosamine - derived from chitin - stimulates manufacturing of substances essential for proper joint function/joint repair stimulation • chondroitin - dervied from bovine/shark cartilage - acts as chondroprotectant • serotonin derivative produced by pineal gland Melatonin • regulates sleep/wake cycle • release coincides w/ darkness, release is suppressed by daylight • mild-moderate knee OA - best evidence • general OA - less evidence n/v/d, abd cramps, HA, possible asthma exacs w/ chondroitin warfarin - increased INR • chondroitin - for urinary incontinence and destrusor instability • jet lag - when traveling across 5+ time zones (strongest data) - take dose close to target bedtime @ new destination and 1-3 nights after arrival • insomnia - taken at desired bedtime rare - reports of next day w/ lights off - improves morning drowsiness, vivid dreams, alertness and quality of sleep HA;

mania, hypomania • htn crisis w/ tyraminecontaining foods • CYP450/3A4 inducer reduces levels of amitriptyline/nortriptyline, midazolam/alprazolam, cyclosporine/tacrolimus, indinavir/nevirapine, imatinib/irinotecan, dig, methadone, omeprazole, OCP, simvastatin, warfarin, verapamil, theophylline allow for 14 day washout period after tx with MAOI before starting • abortifacient - do not use during pregnancy • abd pain, n/v/d, indigestion, flatulence Feverfew inhibit plt aggregation, serotonin release, leukotrienes, prostaglandin synthesis migraine prophylaxis - reduces frequency; less severe sx of pain, n/v, photophobia, hyperacusis • swelling of lips, tongue, oral mucosa (less w/ capsule form) warfarin • abortifacient - avoid in pregnancy Co-Q10 affects mitochrondrial function - anti oxidant • Co-Q10 def, ischemic heart dz likely effective • HF, htn - less evidence well tolerated;
