Ginseng tested in humans and animals

tags: chinese herbal weight loss  natural weight loss pills women  echinacea

These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Uses based on scientific evidenceGrade*
Heart conditions Ginseng appears to have antioxidant effects that may benefit patients with heart disorders. Some studies suggest that ginseng also reduces oxidation of low-density lipoprotein (LDL or "bad") cholesterol and brain tissue. Better studies are needed to make a firm recommendation. B
High blood sugar/glucose intolerance Several studies suggest ginseng may lower blood sugar levels in patients with type 2 diabetes before and after meals. These results are promising, especially because ginseng does not seem to lower blood sugar to dangerous levels. Future research should focus on the long-term effects of ginseng in managing blood sugar levels. B
Immune system enhancement Several studies report that ginseng may boost the immune system, improve the effectiveness of antibiotics in people with acute bronchitis, and enhance the body's response to flu vaccines. Additional studies are needed before a clear conclusion can be reached. B
Type 2 diabetes (adult-onset) Several human studies report that ginseng may lower blood sugar levels in patients with type 2 diabetes. Long-term effects are not clear, and it is not known what doses are safe or effective. People with diabetes should seek the care of a qualified healthcare practitioner and should not use ginseng instead of more proven therapies. Effects of ginseng in type 1 diabetes ("insulin dependent") are not well studied. B
Aplastic anemia Weak studies suggest that ginseng in combination with other herbs may improve cell activity, immune function, and red and white blood cell counts in patients with aplastic anemia. Other studies have found decreases in blood cell counts. High-quality studies of ginseng alone are needed. C
Attention deficit hyperactivity disorder (ADHD) Early small studies suggest that American ginseng may help treat attention deficit hyperactivity disorder in children. However, there is currently not enough evidence to support this use of ginseng. C
Birth outcomes (anoxemic encephalopathy) There is currently not enough evidence to support the use of ginseng for this condition. High-quality studies are needed to understand this relationship. C
Bronchodilator Limited research suggests that ginseng has positive effects on breathing. Further studies are needed in this area. C
Cancer chemotherapy Early studies suggest that ginseng injections may help patients undergoing chemotherapy for various types of cancer. Ginseng may improve body weight, quality of life, and the immune response. Although this evidence is promising, the effect of ginseng alone is not clear. More research using ginseng alone is needed. C
Cancer prevention A few studies report that ginseng taken by mouth may lower the risk of developing some cancers, especially if ginseng powder or extract is used. Study results are controversial, and more research is needed before a clear conclusion can be reached. C
Cardiovascular risk reduction Current evidence does not support the use of ginseng to reduce the risk of heart disease. Some evidence suggests that ginseng may improve blood pressure, blood sugar levels, and cholesterol. High-quality studies are needed. C
Chronic hepatitis B Early studies show that ginseng may improve some aspects of liver function but not others. More research is needed in this area. C
Chronic obstructive pulmonary disease (COPD) Ginseng was reported to improve lung function and exercise capacity in patients with COPD. Further research is needed to confirm these results. C
Congestive heart failure Based on limited research, it is unclear if ginseng improves congestive heart failure. High-quality studies looking at the effect of ginseng alone are needed. C
Coronary artery disease Several studies from China report that ginseng in combination with various other herbs may reduce symptoms of coronary artery disease. Without further evidence on the effects of ginseng specifically, a firm conclusion cannot be reached. C
Dementia Early small studies report that Fuyuan mixture, an herbal combination that contains ginseng, may improve symptoms of multi-infarct dementia. The effects of ginseng alone are not clear, and no firm conclusion can be drawn. C
Diabetic complications (kidney damage) Early evidence suggests that a form of ginseng not commonly available in the United States may improve kidney damage in patients with diabetes. Some research suggests that  Panax notoginseng  may be as effective as the prescription drug Ticlid®. However, more research is needed. C
Erectile dysfunction Early studies suggest that ginseng may help treat erectile dysfunction. Additional high-quality studies are needed. C
Exercise performance Athletes commonly use ginseng as a potential way to improve stamina. However, it remains unclear if ginseng taken by mouth significantly affects exercise performance. Many studies have been published in this area, with mixed results. Better studies are necessary before a clear conclusion can be reached. C
Fatigue A few studies using ginseng extract G115® (with or without multivitamins) report improvements in patients with fatigue of various causes. However, these results are early, and studies have not been high quality. C
Fistula (anal) Early evidence in infants with peri-anal abscesses or anal fistulas suggests that GTTC (Ginseng and Tang-kuei Ten Combination) may speed up recovery. Further research is needed to confirm these results. C
Heart damage (cardiac bypass complications) Early studies suggest that ginseng may have a positive effect on complications of cardiac bypass surgery, including decreasing damage to the lining of the digestive tract. Well-designed studies are needed before a strong recommendation can be made. C
High blood pressure Early research suggests that ginseng may lower blood pressure (systolic and diastolic). It is not clear what doses may be safe or effective. Well-conducted studies are needed to confirm these early results. C
High cholesterol Several low-quality studies have examined the effects of  Panax ginseng  on cholesterol levels. Results are mixed. More studies are needed to understand the effects of ginseng on cholesterol levels. C
Idiopathic thrombocytopenic purpura (refractory) Combination herbal products containing ginseng may help treat refractory idiopathic thrombocytopenic purpura, a blood disorder that does not respond well to treatment. Studies that use ginseng alone are needed. C
Intracranial pressure (ICP) Early research reports that Xuesaitong injection (XSTI), a preparation of  Panax notoginseng , may help decrease pressure inside the skull and benefit coma patients. Further study is needed to confirm these results. C
Kidney dysfunction (hemorrhagic fever with renal syndrome) A combination of herbs that included ginseng was not better than treatment with a conventional medicine plus traditional Chinese medicine. More research is needed in this area because the effects of ginseng alone are unknown. C
Liver protection Early studies suggest that ginseng may have protective effects on the liver. Additional human study is warranted in this area. C
Lung conditions Several studies have looked at the effects of ginseng in a variety of lung conditions. Early results are promising, but many studies have used combination products, making it difficult to evaluate the effect of ginseng. More research using ginseng alone is needed in this area. C
Male infertility Early evidence suggests that ginseng may improve male fertility by increasing the number and movement of sperm. Further studies are needed to determine what dose may be safe and effective. C
Menopausal symptoms Based on limited research, it is unclear if ginseng may help treat menopausal symptoms. Some studies report improvements in depression and sense of well-being, without changes in hormone levels. C
Mental performance Several studies report that ginseng may modestly improve thinking or learning. Benefits have been seen both in healthy young people and in older ill patients. Effects have also been reported with a combination of ginseng and  Ginkgo biloba . However, some mixed results have also been reported. Therefore, even though most available evidence supports this use of ginseng, better research is needed before a strong recommendation can be made. C
Methicillin-resistant Staphylococcus aureus (MRSA) In patients treated with Hochu-ekki-to, which contains ginseng and several other herbs, urinary MRSA has been reported to decrease after 10 weeks. Further study of ginseng alone is necessary in order to draw firm conclusions. C
Mood and cognition in post-menopausal women A review of several studies suggested that ginseng may improve mood and anxiety in postmenopausal women. Additional studies are needed before a firm conclusion may be drawn. C
Neurological disorders Early studies suggest that ginseng may have beneficial effects on neurological disorders. High-quality studies are needed in this area. C
Postoperative recovery (breast cancer) Early studies have tested the effect of a combination product containing ginseng on recovery after surgery among breast cancer patients. Results suggest no benefits in cell counts, but a slightly faster recovery of the iron-carrying component of red blood cells (called hemoglobin). Studies using ginseng alone are needed. C
Pregnancy problems (intrauterine growth retardation) Early studies have found that components of  Panax ginseng  might be useful in treating intrauterine growth retardation. Larger, well-designed studies are needed in this area. C
Premature ejaculation Early studies suggest that applying an herbal combination containing  Panax ginseng  on the penis may help treat premature ejaculation. However, because ginseng was tested with other herbs, its individual effects are unclear. C
Quality of life There is early evidence that  Panax ginseng  or American ginseng may help improve quality of life in both healthy and ill patients, although effects may not be long-lasting unless ginseng is taken continually. More research is needed in this area before a firm conclusion can be reached. C
Radiation therapy side effects Early studies suggest that ginseng may improve fatigue and measures of well-being among patients receiving radiation therapy. However, there is not enough evidence to recommend the use of  Panax ginseng  or American ginseng for this use. C
Respiratory infections Ginseng (CVT-E002) may be safe, well tolerated, and potentially effective for preventing acute respiratory illnesses caused by the flu or the respiratory syncytial virus. More study is needed in this area. C
Sexual arousal (in women) Early studies suggest that a product containing  Panax ginseng , L-arginine,  Ginkgo biloba , damiana, and multivitamin/minerals may improve sexual function in menopausal women and women with decreased sex drives. Studies with  Panax ginseng  alone are needed before strong recommendations can be made. C
Viral myocarditis Poorly described research in patients treated with Shenmai and Shengmai injection (a ginseng preparation) report that there may be some improvement in heart function. More studies are needed before a clear conclusion can be drawn. C
Well-being Several studies have examined the effects of ginseng (with or without multivitamins) on overall well-being in healthy and ill patients, for up to 12 weeks. Most studies are not high quality, and results are mixed. It remains unclear if ginseng is beneficial for well-being in any patient. C

Cigarettes and their smoke contain more than 4,000 chemicals

The Food and Drug Administration is working to lift the smokescreen clouding the ingredients used in cigarettes and other tobacco products.

In June, tobacco companies must tell the FDA their formulas for the first time, just as drugmakers have for decades. Manufacturers also will have to turn over any studies they've done on the effects of the ingredients.

It's an early step for an agency just starting to flex muscles granted by a new law that took effect last June that gives it broad power to regulate tobacco far beyond the warnings now on packs, short of banning it outright.

Companies have long acknowledged using cocoa, coffee, menthol and other additives to make tobacco taste better. The new information will help the FDA determine which ingredients might also make tobacco more harmful or addictive. It will also use the data to develop standards for tobacco products and could ban some ingredients or combinations.

"Tobacco products today are really the only human-consumed product that we don't know what's in them," Lawrence R. Deyton, the director of the Food and Drug Administration's new Center for Tobacco Products and a physician, told The Associated Press in a recent interview.


While the FDA must keep much of the data confidential under trade-secret laws, it will publish a list of harmful and potentially harmful ingredients by June 2011. Under the law, it must be listed by quantity in each brand.

Some tobacco companies have voluntarily listed product ingredients online in recent years but never with the specificity they must give the FDA, said Matt Myers, president of the Campaign for Tobacco-Free Kids.

For example, Altria Group Inc., based in Richmond and the parent company of the nation's largest tobacco maker, Philip Morris USA, has posted general ingredients on its Web site since at least 1999.

Cigarette makers say their products include contain tobacco, water, sugar and flavorings, along with chemicals like diammonium phosphate, a chemical used to improve burn rate and taste, and ammonium hydroxide, used to improve the taste.

Scientific studies suggest those chemicals also could make the body more easily absorb nicotine, the active and addictive component of tobacco.

"Until now, the tobacco companies were free to manipulate their product in ways to maximize sales, no matter the impact on the number of people who died or became addicted," Myers said. "The manner of disclosure previously made it impossible for the government to make any meaningful assessments."

About 46 million people, or 20.6 percent of U.S. adult smoke cigarettes, according to the Centers for Disease Control and Prevention, down from about 24 percent 10 years ago. It also estimates that about 443,000 people in the U.S. die each year from diseases linked to smoking.

Tax increases, health concerns, smoking bans and social stigma continue to cut into the number of cigarettes sold, which were estimated to be down about 12.6 percent in the third quarter compared with the same period last year.

Cigarettes and their smoke contain more than 4,000 chemicals; among them are more than 60 known carcinogens, according to the American Cancer Society. But scientists say they can't yet tell all they'll learn from the new data because so little is known about how the chemicals combine to affect people.

"The reality is that we have known so little over time that it's difficult to know with much accuracy what getting a good look is going to tell us about what we could do in the future," said Dr. David Burns of the University of California-San Diego, scientific editor of several surgeon general reports on tobacco.

The real test is whether the FDA acts on the information it receives, said David Sweanor, a Canadian law professor and tobacco expert. Canadian authorities are collecting similar data, but they haven't taken much action based on it, which is critical, he said. The European Union also has similar submission requirements.

Myers warned that a list of ingredients or an unexplained product label is "just as likely to mislead as it is to inform" if consumers don't know about the relative effects of ingredients.

Altria has supported what it is has called "tough but fair regulation."

But its chief rivals — No. 2 Reynolds American Inc., parent company of R.J. Reynolds, and No. 3 Lorillard, both based in North Carolina — opposed the law. They said it would lock in Altria's share of the market because its size gives it more resources to comply with regulations and future limits on marketing under the law. Altria's brands include Marlboro, which held a 41.9 percent share of the U.S. cigarette market in the third quarter, according to Information Resources Inc.

Sexuality and Chronic Pain

Helping yourself at home
Express your limitations and desires to your partner, says Sueann Mark, PhD, a clinical sexologist with a private practice in San Francisco. "The person in pain needs to take an inventory about what touch is pleasurable and what's not," she says.

While communication is important, it has to be done at the right time: "Talking about these issues is best done when not in bed," she says. Instead, set aside a separate time of day. And remember to think beyond intercourse: "You can find ways to maintain some sexual relationship," she says, including massage, bubble bath, cuddling, and masturbation.

Couples find what works
Through trial and error, couples have found creative ways to maintain intimacy. Jennifer, who lives with chronic migraines, says that she takes advantage of her pain-free days: "We make the best of the times that I feel better than usual," she says. "Even if we have plans, we decide that the most important thing is going to bed together."

Smyres says that she tries to initiate sex once a week and at times other than the evening, when her head often hurts. She's found that talking about sex more with her husband also helps.

Smyres is proof that by communicating and staying in touch with your partner, you can have a rich and loving relationship in spite of chronic pain: "In general, I'm very happy," says Smyres. "My husband is great and my life is wonderful, I'm in the healthiest emotional place that I've ever been."

The prevention and treatment of high blood pressure


Researchers at Oregon Health & Science University's School of Dentistry (www.ohsu.edu/sod) have discovered that nitric oxide is a powerful regulator of a molecule that plays a critical role in the development and function of the nervous system. The finding could someday play a significant role in the prevention and treatment of high blood pressure, which affects about one in three adults in the United States.


Changes in blood pressure are signaled to the brain by nerve cells called baroreceptors. The OHSU dental school team previously found that baroreceptors make a molecule called brain-derived neurotrophic factor (BDNF), which belongs to the family of neurotrophins that play a critical role in the development and plasticity of other nerve cells.

The OHSU dental school team found that nitric oxide is a potent regulator of BDNF in baroreceptor neurons. Nitric oxide is known for its ability to improve the elasticity of blood vessels and to lower blood pressure. It is the active metabolite of nitroglycerin, which has been used to treat coronary artery disease for more than 100 years. Nitric oxide widens small arteries and counteracts artery stiffening, and several lines of evidence also indicate that its deficiency leads to hypertension.


"This is the first study to show the role of nitric oxide in inhibiting BDNF release from peripheral nerve cells," said Agnieszka Balkowiec, M.D., Ph.D., principal investigator, associate professor of integrative biosciences in the OHSU School of Dentistry, and adjunct assistant professor of physiology and pharmacology in the OHSU School of Medicine. "This finding supports our hypothesis that BDNF is involved in establishing connections in the blood pressure control system and could someday play a significant role in the prevention of high blood pressure."


The study was supported by grants from the American Heart Association and the National Institutes of Health's National Heart, Lung, and Blood Institute, including the American Recovery and Reinvestment Act (ARRA) funds.

Dr. Balkowiec teaches physiology and neuroscience to first-year dental students and is often an invited lecturer in dental school courses on orofacial pain. Since 2004 the dental school has received more than $16.4 million in research funding.
