Try our Herbal Remedy and Herbal Medicine: How Ginkgo Is Used Extracts are usually taken from the ginkgo leaf and are used to make tablets, capsules, or teas. Occasionally, ginkgo extracts are used in skin products. What the Science Says about Ginkgo Numerous studies of ginkgo have been done for a variety of conditions. Some promising results have been seen for Alzheimer's disease/dementia, intermittent claudication, and tinnitus among others, but larger, well-designed research studies are needed. Some smaller studies for memory enhancement have had promising results, but a trial sponsored by the National Institute on Aging of more than 200 healthy adults over age 60 found that ginkgo taken for 6 weeks did not improve memory. NCCAM is conducting a large clinical trial of ginkgo with more than 3,000 volunteers. The aim is to see if the herb prevents the onset of dementia and, specifically, Alzheimer's disease; slows cognitive decline and functional disability (for example, inability to prepare meals); reduces the incidence of cardiovascular disease; and decreases the rate of premature death. Ginkgo is also being studied by NCCAM for asthma, symptoms of multiple sclerosis, vascular function (intermittent claudication), cognitive decline, sexual dysfunction due to antidepressants, and insulin resistance. NCCAM is also looking at potential interactions between ginkgo and prescription drugs. Side Effects and Cautions of Ginkgo Side effects of ginkgo may include headache, nausea, gastrointestinal upset, diarrhea, dizziness, or allergic skin reactions. More severe allergic reactions have occasionally been reported. There are some data to suggest that ginkgo can increase bleeding risk, so people who take anticoagulant drugs, have bleeding disorders, or have scheduled surgery or dental procedures should use caution and talk to a health care provider if using ginkgo. Uncooked ginkgo seeds contain a chemical known as ginkgotoxin, which can cause seizures. Consuming large quantities of seeds over time can cause death. Ginkgo leaf and ginkgo leaf extracts appear to contain little ginkgotoxin. It is important to inform your health care providers about any herb or dietary supplement you are using, including ginkgo.

Goldenseal is often combined with echinacea in preparations that are intended to be used for colds. What the Science Says about Goldenseal Few studies have been published on goldenseal's safety and effectiveness, and there is little scientific evidence to support using it for any health problem. Clinical studies on a compound found in goldenseal, berberine, suggest that the compound may be beneficial for certain infections--such as those that cause some types of diarrhea, as well as some eye infections. However, goldenseal preparations contain only a small amount of berberine, so it is difficult to extend the evidence about the effectiveness of berberine to goldenseal. NCCAM is funding a study to understand the mechanism by which berberine may act against tumors. Side Effects and Cautions of Goldenseal Goldenseal is considered safe for short-term use in adults at recommended dosages. Rare side effects may include nausea and vomiting. There is little information about the safety of high dosages or the long-term use of goldenseal. Although drug interactions have not been reported, goldenseal may cause changes in the way the body processes drugs, and could potentially increase the levels of many drugs. However, a study of goldenseal and indinavir, a drug used to treat HIV infection, found no interaction. Other herbs containing berberine, including Chinese goldthread (Coptis trifolia) and Oregon grape (Mahonia aquifolium), are sometimes substituted for goldenseal. These herbs may have different effects, side effects, and drug interactions than goldenseal. Women who are pregnant or breastfeeding should avoid using goldenseal. The berberine in the herb may cause the uterus to contract, increasing the risk of premature labor or miscarriage. Berberine may also be transferred through breast milk, causing life-threatening liver problems in nursing infants. Goldenseal should not be given to infants and young children.

(European mistletoe is different from American mistletoe, which is used as a holiday decoration.)Common Names--European mistletoe, mistletoe

Latin Name--Viscum album L Picture of Mistletoe What Mistletoe Is Used For Mistletoe has been used for centuries in traditional medicine to treat seizures, headaches, and other conditions. Mistletoe is used mainly in Europe as a treatment for cancer. Try our Herbal Remedy and Herbal Medicine: How Mistletoe Is Used The leafy shoots and berries of mistletoe are used to make extracts that can be taken by mouth. In Europe, mistletoe extracts are prescription drugs that are given by injection. In the United States, mistletoe by injection is available only in clinical trials. What the Science Says about Mistletoe Laboratory studies have found that mistletoe kills cancer cells and stimulates the immune system. The use of mistletoe to treat cancer has been studied in Europe in more than 30 clinical trials. Although improvements in survival or quality of life have been reported, almost all of the trials had major weaknesses in their design that raise doubts about the findings. For example, many of the studies had a small number of participants or did not have a control group. NCCAM is sponsoring a clinical trial of mistletoe, given in combination with the drug gemcitabine, for cancer. The study will look at toxicity, safety, and immune system effects of mistletoe extract when combined with this chemotherapy drug. Side Effects and Cautions of Mistletoe Raw, unprocessed mistletoe is poisonous. Eating raw, unprocessed European mistletoe or American mistletoe can cause vomiting, seizures, a slowing of the heart rate, and even death. American mistletoe is unsafe for medicinal use. In countries where commercial mistletoe is available by injection, such as Germany, those extracts are considered to be generally safe when used according to product directions and under the supervision of a health care provider. Injected mistletoe extract may cause itching or redness in the area of the injection. Less commonly, side effects may include more extensive skin reactions, low-grade fevers, or flu-like symptoms. There have been very rare reports of more serious allergic reactions, such as difficulty breathing. Because mistletoe has not yet been proven to be a safe and effective cancer treatment, it should not be used outside of clinical trials. It is important to inform your health care providers about any herb or dietary supplement you are using, including mistletoe. This helps to ensure safe and coordinated care.

What the Science Says about Peppermint oil Results from several studies suggest that peppermint oil may improve symptoms of irritable bowel syndrome. A few studies have found that peppermint oil, in combination with caraway oil, may help relieve indigestion, but this evidence is preliminary. Although there are some promising results, there is no clear-cut evidence to support the use of peppermint oil for other health conditions. Side Effects and Cautions of Peppermint oil Peppermint oil appears to be safe for most adults when used in small doses. Possible side effects include allergic reactions and heartburn. Capsules containing peppermint oil are often coated to reduce the likelihood of heartburn. If they are taken at the same time as medicines such as antacids, this coating can break down more quickly and increase the risk of heartburn and nausea.

Red Clover

The medicinal herb Red Clover as an alternative herbal remedy - Like peas and beans, red clover belongs to the family of plants called legumes. Red clover contains phytoestrogens--compounds similar to the female hormone estrogen. Trifolium pratense (red clover) has anti-inflammatory, diuretic and antispasmodic properties and is also well known as a cleansing herb for skin complaints, including eczema and psoriasis. Its ability to improve lymph functioning and reduce lymphatic swellings helps to purify and detox the system.

Red clover has been cultivated since ancient times, primarily to provide a favorite grazing food for animals. But, like many other herbs, red clover was also a valued medicine. Although it has been used for many purposes worldwide, the one condition most consistently associated with red clover is cancer. Chinese physicians and Russian folk healers also used it to treat respiratory problems. In the nineteenth century, red clover became popular among herbalists as an "alterative" or "blood purifier." This medical term, long since defunct, refers to an ancient belief that toxins in the blood are the root cause of many illnesses. Cancer, eczema, and the eruptions of venereal disease were all seen as manifestations of toxic buildup. Red clover was considered one of the best herbs to "purify" the blood. For this reason, it is included in many of the famous treatments for cancer.Common Names--red clover, cow clover, meadow clover, wild clover

Latin Name--Trifolium pratense Picture of Red Clover Flower What Red clover Is Used For Historically, red clover has been used as an herbal remedy for cancer and respiratory problems, such as whooping cough, asthma, and bronchitis. Current uses of red clover are for menopausal symptoms, breast pain associated with menstrual cycles, high cholesterol, osteoporosis, and symptoms of prostate enlargement. Red Clover is also well known as a cleansing herb for skin complaints. How Red clover Is Used The flowering tops of the red clover plant are used to prepare extracts available in tablets and capsules, as well as in teas and liquid forms. What the Science Says about Red clover Although several small studies of red clover for menopausal symptoms had mixed results, a large study found that red clover had no beneficial effects on menopausal symptoms. There is not enough scientific evidence to determine whether red clover is effective for any other health conditions. NCCAM is studying red clover to learn more about its active components and how they might work in the body, including a clinical trial investigating the safety and effectiveness of red clover for menopausal symptoms. Side Effects and Cautions of Red clover Red clover seems to be safe for most adults when used for short periods of time. No serious adverse effects have been reported. Because red clover contains estrogen-like compounds, there is a possibility that its long-term use would increase the risk of women developing cancer of the lining of the uterus. However, studies to date have been too brief (less than 6 months) to evaluate whether red clover has estrogen-like effects on the uterus. It is unclear whether red clover is safe for women who are pregnant or breastfeeding, or who have breast cancer or other hormone-sensitive cancers. Tell your health care providers about any herb or dietary supplement you are using, including red clover. This helps to ensure safe and coordinated care.

Saw Palmetto

The medicinal herb Saw Palmetto as an alternative herbal remedy - Saw palmetto grows in the southern United States.Common Names--saw palmetto, American dwarf palm tree, cabbage palm

Latin Names--Serenoa repens, Sabal serrulata Picture of Saw Palmetto What Saw Palmetto Is Used For Saw palmetto is used mainly for urinary symptoms associated with an enlarged prostate gland (also called benign prostatic hyperplasia, or BPH). Saw palmetto is also used for other conditions, including chronic pelvic pain, bladder disorders, decreased sex drive, hair loss, and hormone imbalances. How Saw Palmetto Is Used The ripe fruit of saw palmetto is used in several forms, including ground and dried fruit or whole berries. It is available as a liquid extract, tablets, capsules, and as an infusion or a tea. What the Science Says about Saw Palmetto Several small studies suggest that saw palmetto may be effective for treating BPH symptoms. In 2006, a large study of 225 men with moderate-to-severe BPH found no improvement with 320 mg saw palmetto daily for 1 year versus placebo. NCCAM cofunded the study with the National Institute of Diabetes and Digestive and Kidney Diseases. There is not enough scientific evidence to support the use of saw palmetto for reducing the size of an enlarged prostate or for any other conditions. Saw palmetto does not appear to affect readings of prostate-specific antigen (PSA) levels. PSA is protein produced by cells in the prostate. The PSA test is used to screen for prostate cancer and to monitor patients who have had prostate cancer. Side Effects and Cautions of Saw Palmetto Saw palmetto may cause mild side effects, including stomach discomfort. Some men using saw palmetto have reported side effects such as tender breasts and a decline in sexual desire.

How St. John's Wort Is Used The flowering tops of St. John's wort are used to prepare teas and tablets containing concentrated extracts. What the Science Says about St. John's Wort There is some scientific evidence that St. John's wort is useful for treating mild to moderate depression. However, two large studies, one sponsored by NCCAM, showed that the herb was no more effective than placebo in treating major depression of moderate severity. NCCAM is studying the use of St. John's wort in a wider spectrum of mood disorders, including minor depression. Side Effects and Cautions of St. John's Wort St. John's wort may cause increased sensitivity to sunlight. Other side effects can include anxiety, dry mouth, dizziness, gastrointestinal symptoms, fatigue, headache, or sexual dysfunction. Research shows that St. John's wort interacts with some drugs.

How Turmeric Is Used Turmeric's finger-like underground stems (rhizomes) are dried and taken by mouth as a powder or in capsules, teas, or liquid extracts. Turmeric can also be made into a paste and used on the skin. What the Science Says about Turmeric There is little reliable evidence to support the use of turmeric for any health condition because few clinical trials have been conducted. Preliminary findings from animal and laboratory studies suggest that a chemical found in turmeric--called curcumin--may have anti-inflammatory and anticancer properties, but these findings have not been confirmed in people. NCCAM-funded investigators are studying the active chemicals in turmeric and their effects--particularly anti-inflammatory effects--in people to better understand how turmeric might be used for health purposes.
