ABOUT AMERICAN GINSENG



Ginseng is a key ingredient used in Traditional Chinese Medicine. It is also widely used in Western cultures a dietary supplement and botanical element.

There are two types of ginseng. Often both types are taken for a health balancing effect. Consumers take American ginseng for a cooling effect and Asian ginseng for a heating effect.

Ginseng has been used in traditional Chinese medicine for centuries.



This slow-growing, short plant with fleshy roots can be classified three ways, depending on how long it is grown: fresh, white or red.



Fresh ginseng is harvested before 4 years, while white ginseng is harvested between 4–6 years and red ginseng is harvested after 6 or more years.



There are many types of this herb, but the most popular are American ginseng (Panax quinquefolius) and Asian ginseng (Panax ginseng).



American and Asian ginseng vary in their concentration of active compounds and effects on the body. It is believed that American ginseng works as a relaxing agent, whereas the Asian variety has an invigorating effect.



Ginseng contains two significant compounds: ginsenosides and gintonin. These compounds complement one another to provide health benefits.



Here are 7 evidence-based health benefits of ginseng.



1. Potent Antioxidant That May Reduce Inflammation



Ginseng has beneficial antioxidant and anti-inflammatory properties.



Some test-tube studies have shown that ginseng extracts and ginsenoside compounds could inhibit inflammation and increase antioxidant capacity in cells.



For example, one test-tube study found that Korean red ginseng extract reduced inflammation and improved antioxidant activity is skin cells from people with eczema.



The results are promising in humans, as well.



One study investigated the effects of having 18 young male athletes take 2 grams of Korean red ginseng extract three times per day for seven days.



The men then had levels of certain inflammatory markers tested after performing an exercise test. These levels were significantly lower than in the placebo group, lasting for up to 72 hours after testing.



However, it should be noted that the placebo group got a different medicinal herb, so these results should be taken with a grain of salt and more studies are needed.



Lastly, a larger study followed 71 postmenopausal women who took 3 grams of red ginseng or a placebo daily for 12 weeks. Antioxidant activity and oxidative stress markers were then measured.



Researchers concluded that red ginseng may help reduce oxidative stress by increasing antioxidant enzyme activities.




2. May Benefit Brain Function



Ginseng could help improve brain functions like memory, behavior and mood.



Some test-tube and animal studies show that components in ginseng, like ginsenosides and compound K, could protect the brain against damage caused by free radicals.



One study followed 30 healthy people who consumed 200 mg of Panax ginseng daily for four weeks. At the end of the study, they showed improvement in mental health, social functioning and mood.



However, these benefits stopped being significant after 8 weeks, suggesting that ginseng effects might decrease with extended use.



Another study examined how single doses of either 200 or 400 mg of Panax ginseng affected mental performance, mental fatigue and blood sugar levels in 30 healthy adults before and after a 10-minute mental test.



The 200-mg dose, as opposed to the 400-mg dose, was more effective at improving mental performance and fatigue during the test.



It is possible that ginseng assisted the uptake of blood sugar by cells, which could have enhanced performance and reduced mental fatigue. Yet it is not clear why the lower dose was more effective than the higher one.



A third study found that taking 400 mg of Panax ginseng daily for eight days improved calmness and math skills.



What’s more, other studies found positive effects on brain function and behavior in people with Alzheimer's disease.




3. Could Improve Erectile Dysfunction



Research has shown that ginseng may be a useful alternative for the treatment of erectile dysfunction (ED) in men.



It seems that compounds in it may protect against oxidative stress in blood vessels and tissues in the penis and help restore normal function.



Additionally, studies have shown that ginseng may promote the production of nitric oxide, a compound that improves muscle relaxation in the penis and increases blood circulation.



One study found that men treated with Korean red ginseng had a 60% improvement in ED symptoms, compared to 30% improvement produced by a medication used to treat ED.





Moreover, another study showed that 86 men with ED had significant improvements in erectile function and overall satisfaction after taking 1,000 mg of aged ginseng extract for 8 weeks.



However, more studies are needed to draw definite conclusions about the effects of ginseng on ED.




4. May Boost the Immune System



Ginseng may strengthen the immune system.



Some studies exploring its effects on the immune system have focused on cancer patients undergoing surgery or chemotherapy treatment.



One study followed 39 people who were recovering from surgery for stomach cancer, treating them with 5,400 mg of ginseng daily for two years.



Interestingly, these people had significant improvements in immune functions and a lower recurrence of symptoms.



Another study examined the effect of red ginseng extract on immune system markers in people with advanced stomach cancer undergoing post-surgery chemotherapy.



After three months, those taking red ginseng extract had better immune system markers than those in the control or placebo group.



Furthermore, a study suggested that people who take ginseng could have up to a 35% higher chance of living disease-free for five years after curative surgery and up to a 38% higher survival rate compared to those not taking it.



It seems that ginseng extract could enhance the effect of vaccinations against diseases like influenza, as well.



Even though these studies show improvements in immune system markers in people with cancer, more research is needed to demonstrate the efficacy of ginseng in boosting resistance to infections in healthy people.




5. May Have Potential Benefits Against Cancer



Ginseng may be helpful in reducing the risk of certain cancers.



Ginsenosides in this herb have been shown to help reduce inflammation and provide antioxidant protection.



The cell cycle is the process by which cells normally grow and divide. Ginsenosides could benefit this cycle by preventing abnormal cell production and growth.



A review of several studies concluded that people who take ginseng may have a a 16% lower risk of developing cancer.



Moreover, an observational study suggested that people taking ginseng could be less likely to develop certain types of cancer, such as lip, mouth, esophagus, stomach, colon, liver and lung cancer, than those who do not take it.



Ginseng may also help improve the health of patients undergoing chemotherapy, reduce side effects and enhance the effect of some treatment drugs.



While studies on the role of ginseng in cancer prevention show some benefits, they remain inconclusive.




6. May Fight Tiredness and Increase Energy Levels



Ginseng has been shown to help fight fatigue and promote energy.



Various animal studies have linked some components in ginseng, like polysaccharides and oligopeptides, with lower oxidative stress and higher energy production in cells, which could help fight fatigue.



One four-week study explored the effects of giving 1 or 2 grams of Panax ginseng or a placebo to 90 people with chronic fatigue.



Those given Panax ginseng experienced less physical and mental fatigue, as well as reductions in oxidative stress, than those taking the placebo.



Another study gave 364 cancer survivors experiencing fatigue 2,000 mg of American ginseng or a placebo. After eight weeks, those in the ginseng group had significantly lower fatigue levels than those in the placebo group.



Furthermore, a review of over 155 studies suggested that ginseng supplements may not only help reduce fatigue but also enhance physical activity.




7. Could Lower Blood Sugar



Ginseng seems to be beneficial in the control of blood glucose in people both with and without diabetes.



American and Asian ginseng have been shown to improve pancreatic cell function, boost insulin production and enhance the uptake of blood sugar in tissues.



Moreover, studies show that ginseng extracts help by providing antioxidant protection that reduce free radicals in the cells of those with diabetes.



One study assessed the effects of 6 grams of Korean red ginseng, along with the usual anti-diabetic medication or diet, in 19 people with type 2 diabetes.



Interestingly, they were able to maintain good blood sugar control throughout the 12-week study. They also had an 11% decrease in blood sugar levels, a 38% decrease in fasting insulin and a 33% increase in insulin sensitivity.



Another study showed that American ginseng helped improve blood sugar levels in 10 healthy people after they performed a sugary drink test.



It seems that fermented red ginseng could be even more effective at blood sugar control. Fermented ginseng is produced with the help of live bacteria that transform the ginsenosides into a more easily absorbed and potent form.Trusted Source



In fact, a study demonstrated that taking 2.7 grams of fermented red ginseng daily was effective at lowering blood sugar and increasing insulin levels after a test meal, compared to a placebo.

Overview Information



American ginseng (Panax quinquefolis) is an herb that grows mainly in North America. Wild American ginseng is in such high demand that it has been declared a threatened or endangered species in some states in the United States.




People take American ginseng by mouth for stress, to boost the immune system, and as a stimulant.



American ginseng is often used to fight infections such as colds and flu. There is some evidence that it might help prevent colds and flu and make symptoms milder when infections do occur.



American ginseng is used for other infections including HIV/AIDS, infections of the intestine (dysentery), and particular infections (Pseudomonas infections) that are common in people with cystic fibrosis.



Some people use American ginseng to improve digestion and for loss of appetite, as well as for vomiting, inflammation of the colon (colitis), and inflammation of the lining of the stomach (gastritis).



American ginseng is also used for low iron in the blood (anemia), diabetes, insulin resistance related to HIV treatments, cancer-related fatigue, high blood pressure, trouble sleeping (insomnia), nerve pain, erectile dysfunction (ED), fever, hangover symptoms, attention deficit-hyperactivity disorder (ADHD), blood and bleeding disorders, breast cancer, dizziness, headaches, convulsions, fibromyalgia, “hardening of the arteries” (atherosclerosis), memory loss, rheumatoid arthritis, schizophrenia, improving athletic performance, improving mental performance, as an anti-aging aid, menopausal symptoms, complications during pregnancy or childbirth, and for nervous exhaustion (neurasthenia).



You may also see American ginseng listed as an ingredient in some soft drinks. Oils and extracts made from American ginseng are used in soaps and cosmetics.



Don’t confuse American ginseng with Siberian ginseng (Eleutherococcus senticosus) or Asian ginseng (Panax ginseng). They have different medicinal effects.





How does it work?



American ginseng contains chemicals called ginsenosides that seem to affect insulin levels in the body and lower blood sugar. Other chemicals, called polysaccharides, might affect the immune system.

Monday, September 23, 2019







American ginseng is LIKELY SAFE when taken by mouth appropriately, short-term. Doses of 100-3000 mg daily have been used safely for up to 12 weeks. Single doses of up to 10 grams have also been safely used. In addition, a specific American ginseng extract called CVT-E002 (Cold-FX, Afexa Life Sciences, Canada) has also been used safely for up to 4 months.





When taken by mouth, American ginseng can cause some side effects including diarrhea, itching, trouble sleeping (insomnia), headache, and nervousness. In some people, American ginseng might also cause rapid heartbeat, increased blood pressure or decreased blood pressure, breast tenderness, vaginal bleeding in women, and other side effects. Uncommon side effects that have been reported include a severe rash called Stevens-Johnson syndrome, liver damage, and severe allergic reaction.



Special Precautions & Warnings:



Children: American ginseng is POSSIBLY SAFE for children when taken by mouth appropriately, short-term. A specific American ginseng extract called CVT-E002 (Cold-FX, Afexa Life Sciences, Canada) has been used in doses of 4.5-26 mg daily for 3 days in children 3-12 years-old.



Pregnancy and breast-feeding: American ginseng is POSSIBLY UNSAFE in pregnancy. One of the chemicals in Panax ginseng, a plant related to American ginseng, has been linked to possible birth defects. Do not take American ginseng if you are pregnant.



There is not enough reliable information about the safety of taking American ginseng if you are breast feeding. Stay on the safe side and avoid use.



Diabetes: American ginseng might lower blood sugar. In people with diabetes who are taking medications to lower blood sugar, adding American ginseng might lower it too much. Monitor your blood sugar closely if you have diabetes and use American ginseng.



Hormone-sensitive conditions such as breast cancer, uterine cancer, ovarian cancer, endometriosis, or uterine fibroids: American ginseng preparations that contain chemicals called ginsenosides might act like estrogen. If you have any condition that might be made worse by exposure to estrogen, don’t use American ginseng that contains ginsenosides. However, some American ginseng extracts have had the ginsenosides removed (Cold-fX, Afexa Life Sciences, Canada). American ginseng extracts such as these that contain no ginsenosides or contain only a low concentration of ginsenosides do not appear to act like estrogen.



Trouble sleeping (insomnia): High doses of American ginseng have been linked with insomnia. If you have trouble sleeping, use American ginseng with caution.



Schizophrenia (a mental disorder): High doses of American ginseng have been linked with sleep problems and agitation in people with schizophrenia . Be careful when using American ginseng if you have schizophrenia.



Surgery: American ginseng might affect blood sugar levels and might interfere with blood sugar control during and after surgery. Stop taking American ginseng at least 2 weeks before a scheduled surgery.




The following doses have been studied in scientific research:



BY MOUTH:

For reducing blood sugar in people with type 2 diabetes: 3 grams up to 2 hours before a meal. American ginseng should be taken within 2 hours of a meal. If it is taken too long before eating, the blood sugar might become too low.100-200 mg of American ginseng have been taken daily for up to 8 weeks.




For preventing upper respiratory tract infections such as the common cold or flu: a specific American ginseng extract called CVT-E002 (Cold-fX, Afexa Life Sciences, Canada) 200 mg twice daily for 3-4 months has been used.
