Aloe

Back Ground: Aloe or Aloe Vera is a perennial plant that belongs to the Liliaceae family. Aloe Vera has been used medicinally since 1500 BC primarily for skin integrity and the healing process. Queen Nefertiti and Cleopatra used it daily as part of their beauty regime. Aloe has at least 75 different compounds that include 20 different Amino Acids, 20 minerals, vitamins and water. Medicinal use: Several Studies have shown that Aloe Vera can inhibit a Thromboxane, which is an inhibitor of wound healing. By inhibiting this it greatly increases the wound healing process and reduces inflammation along cuts and burns. There is also Magnesium Lactate that comes from Aloe that can block histamines that trigger itchiness and skin irritation. This can be used to further prevent against skin breakdown such as pressure ulcers. When Aloe is taken, it helps synthesis the collagen in the body by changing its chemical composition to increase the cross-linking effects and increases wound healing. Additionally, mucopolysaccharides along with amino acids and zinc present in Aloe Vera can lead to skin integrity, moisture retention, erythema reduction, and helps to prevent skin ulcers. Dosage routes: Topical, liquid gel capsule, tincture, liquid Positive Effects of Aloe Vera: treats wounds, psoriasis, mouth sores, ulcers, diabetes herpes, bedsore and burn wounds. It is known for its anti-tumor, anti-inflammatory, skin protection, anti-diabetic, anti-bacterial, anti-viral, antiseptic, and wound healing properties Adverse Effects: Hypoglycemia, can sometimes cause stomach cramps and pain, liver problems, Bloody urine, low potassium, weight loss, heart disturbances. Drug Interactions: There are no known drug interactions at this time associated to Aloe Vera. Do not take : if you have GI disturbances (orally), appendicitis (orally), liver/kidney disease (orally) or peptic ulcer disease (orally)

Interactions: Chamomile has been found to interact with sedatives, NSAIDs, anti-platelet drugs, and aspirin. Nursing Implications: Chamomile is not contraindicated for breastfeeding mothers. It is sometimes used as a galactagogue. Galactagogues are believed to increase breastmilk production, though this has not been proven.

Hawthorn

Indications for us it treats/prevents: Hawthorn can be used for countless purposes mainly for treatment. Studies shows that is is used for a disease of the heart, and blood vessels such as congestive heart failure, chest pain, and irregular heartbeat. It can also be used to treat both low blood pressure and high blood pressure, atherosclerosis, and high cholesterol. Hawthorn can also be used for the digestive system, regarding indigestion, diarrhea, and stomach pain. The herb can be used to reduce anxiety and be used as a sedative to increase urine output and for menstrual problems. Hawthorn can also be used to treat tapeworms and intestinal infections. Some people utilize hawthorn and apply it to the skin for boils, sores, and ulcers. Hawthorn is possibly safe for short term use (up to 16 weeks). It is not known if hawthorn has been successful as a long-term use. Adverse effects: Taking hawthorn can cause nausea, upset stomach, fatigue, sweating, headache, dizziness, palpitations, nosebleeds, insomnia, and agitation. Interactions: This herb cannot be taken with digoxin (Lanoxin) because it can increase the effects of digoxin and increase the risks of side effects. It can not be taken with any blood pressure medication because it can cause your blood pressure to decrease. Males can't take hawthorn and any medication for sexual dysfunction because it may cause your blood pressure to go too low. Lastly, this herb can't be taken with any medication that increases the blood flow to the heart (nitrates) because it may increase the chance of dizziness and lightheadedness. Interacting Hawthorn with drugs may lead to toxic levels of cardiac glycosides (e.g., digitalis). Nursing implications: For pregnant and breast feeding: not enough tests have been conducted to know to see the effects of hawthorn during pregnancy or while breastfeeding therefore patient should stay on the safe side and avoid the use. If client has a heart condition and is taking any heart medications avoid the use of hawthorn. Preoperative patients should avoid using this herb 2 weeks before surgery because hawthorn may slow blood clotting and increase the risk of bleeding during and after surgery. Always monitor for any unusual or adverse effects while taking Hawthorn including therapeutic effects.

Garlic

Indications for use: Garlic can be used for many purposes such as, treating or preventing high blood cholesterol, high blood pressure, coronary artery disease, and the common cold, as well as in attempts to prevent cancer (stomach, colon or rectal) and other diseases. Adverse effects: Breath and body odor, burning sensation in the mouth or stomach, heartburn, upset stomach, nausea, vomiting or diarrhea. Interactions: Possible interference with hypoglycemic therapy and anticoagulant Warfarin (Coumadin). Garlic also interacts with Isoniazid, Saquinavir, HIV or AIDS medications, and NSAIDS.

Do not give any herbal/health supplement to a child without medical advice. Garlic taken by mouth in large doses may be harmful to children.

Glucosamine

Indications for use: Glucosamine is most commonly used to provide relief pain and improve joint function for those with osteoarthritis, rheumatoid arthritis, and joint pain. Glucosamine is stated to have further uses but has not been proven with adequate research such as heart disease, knee pain, multiple sclerosis, stroke, jaw pain, glaucoma, interstitial cystitis, temporomandibular joint disorder, and weight loss. Adverse effects: Glucosamine is mostly safe in adults but can cause the following side effects: nausea, heartburn, diarrhea, constipation, drowsiness, skin reactions, headaches, and hyperglycemia. Interactions: Glucosamine has a MAJOR interaction with Warfarin. It may enhance the anticoagulant effects of warfarin. Glucosamine may also cause an increase in insulin resistance, which results in the need for higher dosages of oral hypoglycemics or insulin. Glucosamine may also decrease the effectiveness of chemotherapy medications such as etoposide, teniposide and doxorubicin Lastly, it may decrease the effectiveness of acetaminophen. Nursing implications: Women who are pregnant or breastfeeding should not take glucosamine since there is not enough research to support its safe use. People who are allergic to shellfish should not take glucosamine since the supplement is derived from crabs, shrimps and the shell of lobsters. Stop taking glucosamine at least two weeks before a scheduled surgery as it may impact the body's ability to regulate blood sugar. Monitor pain and range of motion periodically while taking glucosamine.

Valerian

Indications for use: Valerian is an herb sold as a dietary supplement in the United States. It is a native plant to Europe and Asia. Valerian is used to treat sleep disorders such as insomnia. There are other uses that have not been proven by research such as: treatment for attention deficit-hyperactivity disorder, anxiety disorders, depression, restlessness, chronic fatigue syndrome, and tremors. Adverse effects: Headaches, dizziness, and gastrointestinal disturbances are the most common effects reported in clinical trials but similar effects were also reported for the placebo. Interactions: Valerian may have additive therapeutic and adverse effects if taken with Xanax, Valium, Ativan, and Central nervous system depressants. Nursing implications: Women who are pregnant or nursing should not take valerian without medical advice because the possible risks to the fetus or infant have not been evaluated.

Black Cohosh

Indications: To treat the symptoms of menopause, PMS, painful periods, acne, osteoporosis, and starting labor in pregnant women. Other lesser know treatments are anxiety, rheumatism, insect repellent, fever, and cough. Adverse Effects: Possibly safe when taken by mouth by adults for one year. Mild side effects include: upset stomach, cramping, rash, a heavy feeling, vaginal spotting / bleeding, and weight gain. Interactions: Atorvastatin commonly know Lipitor has harmful effects with Black Cohosh. Black Cohosh has the potential to harm the liver, so taking Lipitor might increase the chance of liver damage. However, it's not enough scientific data to know if this is an impact or concern. Please alert your healthcare provider before taking this herb while on Lipitor. Cisplatin also known as Plantinol- AQ is a cancer treating medicine that will lose it effectiveness if taken with Black Cohosh. Any Medicine that is broken down in the liver should not be taken with Black Cohosh. Due to the possibility of liver damage. Some examples are : Elavil, Clozaril, Fentanyl, Zofran, and Tylenol. Nursing: Possibly unsafe for pregnancy and breastfeeding. Since Black Cohosh can act as a female hormone, it increases the risk of mischarges.

Researchers suggest the use of Kava to help treat symptoms or side effects of anxiety disorders. Kava is also used to help induce sleep. Kava has anxiolytic effect and for this reason people use it as an alternative to help with sleep disorders. Adverse effects: Researchers suggest that Kava may cause liver damage. Symptoms include fatigue, nausea, jaundice, abnormal enzyme levels, rash and fever. Long term use of Kava in high doses can cause dry, scaly skin, yellow skin, heart and eye problems. Interactions: Kava interacts with alcohol, consuming both alcohol and Kava could increase a person's risk of developing liver damage. Kava also interacts with other drugs such as benzodiazepines and anti-depressants. For this reason people should consult their doctor's before using Kava. Nursing Implications: Little research has been done on the use of Kava in women who are pregnant. Until more research is conducted, Kava should be avoided in pregnant women. Kava has been banned in several countries not including the U.S. Kava is known to cause possible liver damage so people should try alternative therapies to treat anxiety disorders and improve quality of sleep.

Saw Palmetto

Uses-Saw palmetto is a tree use to make medicine. It is mostly used for decreasing symptoms of an enlarged prostate (benign prostatic hypertrophy-BPH). It is also used to prevent complications from prostate surgery and other types of prostate conditions. It has a suggested use for treating baldness in men and women. Research has shown that taking 320 mg of saw palmetto daily for two months before prostate surgery can reduce the time spent in surgery, blood loss, the development of problems during surgery, and the total time spent in the hospital. However, taking 160mg for 5 weeks prior to surgery did not lower the risk for problems. Side effects and Safety-Saw palmetto is likely safe for most people when taken by mouth for up to three years. Some people have reported dizziness, headache, nausea, vomiting, constipation, and diarrhea. Some people have reported that it causes impotence. There is some concern that saw palmetto may cause liver or pancreas problems. However, these side effects do not seem to occur anymore often with saw palmetto than with a sugar pill and not enough information to know if it causes these side effects. Saw palmetto is likely unsafe when taken by mouth during pregnancy or breastfeeding. It acts like a hormone, and this could be dangerous to the pregnancy. Saw palmetto might slow blood clotting. There is some concern that it might cause extra bleeding during and after surgery. Stop using saw palmetto at least 2 weeks before a scheduled surgery. Saw palmetto is possibly safe when administered into the rectum appropriately for up to 30 days. It is not known if its safe to use longer. Interactions- It has a moderate interaction with birth control pills. It may decrease the effectiveness of birth control pills. Some medications that slow blood clotting might increase the chances of bruising and bleeding. These medications include aspirin, clopidogrel (Plavix), diclofenac (Voltaren, Cataflam, etc.), Ibuprofen (Advil, Motrin, etc.), naproxen (Anaprox, Naprosyn, etc.), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, warfarin (Coumadin) and others.
