Access free multiple choice questions on this topic. They differ from herbal supplements in that they use FDA-regulated, purified ingredients.
Therefore, preparations may contain a portion of the plant or the whole plant and vary in their consistency. Herbal supplements are most often sold in solid form capsules, pills, tablets, lozenges but are also available in liquid or powder form.
This paper focuses on the following commonly used herbal supplements in the United States. These are:. Saw palmetto is indigenous to the southeastern United States. Historically, it was used by Native Americans to treat genitourinary symptoms, relieve inflamed mucous membranes, increase testicular function and increase breast size.
Saw palmetto has been shown to inhibit 5a-reductase, an enzyme that converts testosterone to dihydrotestosterone. Studies have proposed that fatty acids may be responsible for inhibiting 5a-reductase, but which one s is unknown.
Garlic Allium sativum is among the most researched herbal supplements and is the second most used complementary therapy. Studies have shown that it has hepatoprotective, neuroprotective, and antioxidant properties.
In severely hypertensive patients, garlic was shown to reduce blood pressure and cardiovascular events. A daily dose of 0. Ginkgo biloba is commonly used to improve memory and cognition in the elderly suffering from impaired cerebral circulation.
Mitochondrial dysfunction is one theory proposed as the leading cause of cognitive decline. Specifically, Gingko biloba was shown to improve endocrine homeostasis, regulate hormone sensitivity, maintain endothelial microvascular integrity, and proteolyze tau proteins.
Echinacea is a native species to eastern and central North America. Historically, Native Americans used Echinacea for treating colds, bronchitis, flu, and respiratory infections. It has also demonstrated antiviral, anti-inflammatory, and antimicrobial effects.
Intracellular bactericidal activity and enhanced phagocytosis were also observed. Black cohosh Actaea racemosa is commonly used to treat premenstrual syndrome PMS , dysmenorrhea, menopausal symptoms, and in particular, hot flashes.
It has also seen increased use in women who have breast cancer. Triterpene glycosides are one group suggested as the compounds responsible. The same dose given orally for 28 days decreased breast tumor size and metastasis to the lungs and liver in mice. Ginseng is used commonly to boost energy, enhance physical and mental performance, treat erectile dysfunction, and strengthen the immune response.
Ginseng is a generic term that represents several species in the genus Panax. These include Panax quinquefolius L American ginseng , Panax ginseng, and Panax japonicus Asian ginseng. Ginseng is composed of a diverse amount of active compounds that affect many metabolic pathways.
Of those, ginsenosides have been shown to have clinical significance. They are found in the plant's roots but have also been reported to be abundant in the berries. They also regulate immunocytes and cytokines, which affect cell-mediated and humoral immunity.
By downregulating the RNA level of MDR-1, it increased sensitivity to gemcitabine, cisplatin, paclitaxel, and epirubicin. Hawthorn Crataegus monogyna is commonly used for heart-related conditions, specifically as a supportive treatment for angina, atherosclerosis, heart failure, angina, atherosclerosis, and high blood pressure.
Hawthorn's effects on the heart were first reported in the first century AD and have been well established. The WS extract contains oligomeric procyanidins OPC , which have been shown to act as free radical scavengers.
John's Wort Hypericum perforatum is commonly used to treat mild-to-moderate depression. John's Wort as a medicinal herb is traceable back to the ancient Greeks who used it to treat burns, as an astringent to arrest diarrhea, and as a diuretic. John's Wort that work synergistically to provide its antidepressant and anti-inflammatory attributes.
At a daily dosage of to mg, St. John's Wort was more efficacious than standard antidepressant therapy in patients with mild-to-moderate depression. John's Wort, were found to be active against gram-positive and gram-negative bacteria.
John's Wort is active against multi-drug resistant bacteria, with extracts imparting potent antibacterial activity against methicillin-resistant Staphylococcus aureus MRSA. Goldenseal Hydrastis canadensis has long been used for its antiseptic qualities and activity against colds, the flu, and inflammation of the nares.
It is indigenous to eastern North America and southeastern Canada. Native Americans used the roots of goldenseal to treat skin and eye infections and gastrointestinal irritation. Feverfew Tanacetum parthenium is commonly used for migraine headaches and menstrual cramps.
It is native to Asia Minor but cultivated worldwide. Major active compounds found in feverfew include sesquiterpene lactones, 3b-hydroxy parthenolide, parthenolide, canin, and artecanin. A significant concern of herbal supplementation is that many patients use herbal supplements but underreport them to their clinicians.
Not knowing if a patient uses herbal supplements may inadvertently complicate treatment. Since some herbal supplements are known to inhibit or enhance prescription drugs, not knowing what herbal supplements a patient is taking can lead to either ineffective treatment or toxicity and harmful side effects.
A significant concern of herbal supplements clinically is their interaction with cytochrome p enzymes CYP Especially when patients are taking prescription drugs and herbal supplements concurrently.
Herbal supplements may inhibit these enzymes, causing increased exposure to toxic compounds or induce them, increasing the number of toxic compounds produced or releasing reactive oxygen species ROS , leading to organ damage.
Terpenes in black cohosh and Echinacea extract may inhibit CYP enzymes. The other possible interaction is when an herbal supplement has a similar mechanism of absorption, distribution, metabolism, or excretion ADME to a prescribed drug.
In these cases, changing the prescribed drug dosage can safely counteract the negative interaction. Garlic may act as a blood thinner by inhibiting platelets and negating the effects of anticoagulants. These include colchicine, digoxin, doxorubicin, quinidine, rosuvastatin, tacrolimus, and verapamil.
People with ragweed allergies may be allergic to Echinacea as well. Six months of continuous ingestion of different Echinacea preparations showed no toxic effects. Black cohosh has been shown to interact with the OATP2B1 enzyme; this may reduce the efficacy of fexofenadine, glyburide, amiodarone, and many statin medications.
In several human trials, Asian ginseng was shown not to affect CYP2E1, CYP1A2, CYP2D6, or P-gp. Gingko biloba has been shown to inhibit platelet aggregation. Several studies, however, showed that Gingko did not increase bleeding risk or have a significant effect on hematologic parameters.
Goldenseal has been shown to inhibit CYP2D6 and CYP3A4. It is strongly recommended to avoid taking goldenseal with most prescription and over-the-counter medications. It may interact reduce effectiveness with irinotecan, protease inhibitors, digoxin, cyclosporine, tacrolimus, warfarin, and oral contraceptives.
Saw palmetto has been shown not to affect CYP1A2, CYP2D6, CYP3A4, or CYP2E1 enzymes. Reported possible side effects of hawthorn include nausea, dizziness, vertigo, fatigue, sweating, headache, palpitations, and epistaxis.
It is not recommended during pregnancy because it can cause uterine stimulation. American consumers trust that their prescription drugs are of high quality and are consistent in purity and potency, often without question. According to a study done in , this expectation has been transferred over to herbal supplements despite their lack of regulation in the United States.
Preparation is another issue affecting herbal supplements. Herb preparation and the parts used significantly affect its efficacy and attributes. One method of alleviating these issues is through certification. In , the FDA established regulations for dietary supplements called Current Good Manufacturing Practice cGMP.
It is a list of nonbinding recommendations in manufacturing, labeling, packing, or holding operations for dietary supplements. Manufacturers can certify their products to verify active components and concentrations of heavy metals and other possible contaminants.
Further research is necessary to standardize extraction methods and the preparation of herbal supplements so that their effectiveness is consistent. Because patients are generally reluctant to disclose their herbal supplementation, it is crucial to develop a trusting relationship that would allow patients to discuss dietary supplement use without reservation.
All interprofessional healthcare team members need to be on the same page regarding herbal supplements, share information through open communication between team members, and deliver a consistent message to the patient.
This approach will optimize therapeutic efficacy and reduce potential adverse effects. In detecting possible interactions between supplements and drugs, thorough notes should be taken on herbal supplement usage, including initiation and discontinuation. Clinicians need to understand whether an herbal supplement affects a prescribed drug's clinical effect without affecting its dosage or whether it is affecting the concentration in the blood and, therefore, its pharmacologic action pharmacokinetics.
This understanding will lead to a more informed decision on whether to change the dosage of a drug or discontinue the supplement s in question altogether.
Nurses need to include these agents in the patient's medication record. The pharmacist can consult with the clinician to check for interactions, as these are often not benign substances and can alter drug therapy.
