Ginseng is a root with an ancient history of use as medicine. Today, scientific research is confirming the herb’s potential to improve health and help protect against diseases. Ginseng is often used today as an exercise performance enhancer, an aphrodisiac, and an immune system booster. It’s commonly dried and powdered, then taken as capsules. However, you can also find ginseng tea and ginseng tinctures. The taste of ginseng is bitter and cleansing.
Types of Ginseng
The two varieties of ginseng include:
- Asian ginseng, also called Korean ginseng (scientific name Panax ginseng)
- American ginseng, or Panax quinquefolius
Asian and American ginseng contain similar compounds, but given they grow in different climates, they aren’t exactly the same. While both are adaptogens and have similar health-protective benefits, Asian ginseng is more stimulating, and American ginseng is more calming.
7 Ginseng Benefits and Uses
Ginseng has been used in traditional Chinese medicine (TCM) and other ancient systems of medicine for good reasons. Here are the effects of ginseng that have been reported in today’s scientific literature:
1. Boosts Brain Function
One of the most promising studies done on ginseng’s benefits is a 12-week study involving Alzheimer’s patients. By the end of the study, the ginseng group tested higher in cognitive performance relative to the control group. Young people may also benefit from the cognitive enhancement ginseng provides. In a trial involving children with ADHD, ginseng combined with omega-3 supplements was shown to improve memory recall and attention span. In another study, ginseng given to healthy adults was shown to improve cognitive performance in mental arithmetic tasks and relieve mental fatigue.
2. Lowers High Blood Sugar
Bioactive molecules in ginseng, known as ginsenosides, are responsible for anti-diabetic effects in people with prediabetes and in people with type 2 diabetes. As many as 12 human trials have been done on diabetes patients, and ginseng has been found to improve glucose uptake and regulate insulin production to produce anti-diabetic effects.
3. Increases Libido
Asian ginseng in particular is known for boosting libido and reversing symptoms of erectile dysfunction. It’s known as an aphrodisiac in Korean and Chinese systems of medicine. Scientific studies on both animals and humans confirm it enhances sexual behavior. In fact, ginseng is shown to increase sperm count and quality in men. In a study on menopausal women, Asian ginseng was shown to improve sexual arousal.
4. May Improve Energy Levels
As an adaptogen, ginseng can help you adapt to stress, increase your energy levels, and even improve exercise performance. According to one review of 10 studies, ginseng reversed chronic fatigue symptoms in just 15 days.
5. Helps Protect Against Cancer
In addition to providing antioxidant support and lowering inflammation, ginseng also has direct anti-cancer actions. In one meta-analysis of scientific studies that looked at the impact of ginseng on your risk for cancer, researchers concluded regularly taking ginseng can lower your cancer risk by 16%.
6. Lowers Cholesterol
High cholesterol elevates your risk for heart disease, as the buildup of unhealthy cholesterol in your bloodstream causes arterial plaque. The anti-cholesterol plant chemicals found in ginseng can help protect against heart disease by lowering high cholesterol levels. Studies show that ginseng supplementation lowers levels of harmful cholesterol known as LDL cholesterol while raising levels of HDL cholesterol, which is the healthy fat that helps keep LDL cholesterol levels down.
7. Reduces Inflammation
Chronic inflammation is another factor that contributes to the development of heart disease, as well as other chronic diseases. Ginseng has been found to have powerful inflammation-lowering effects. In one animal study, ginseng’s inflammation-lowering capacity was attributed to its ability to reverse brain damage. By keeping inflammation at bay, regular ginseng supplementation could potentially help prevent neurodegenerative diseases, heart disease, and even depression — which has also been linked with chronic inflammation.
Ginseng Doses and Side Effects
As with any herbal supplement, you should adhere to the recommended daily dosage on the product label. Some products may be concentrated in ginseng’s active chemicals, whereas other products may be powdered in ginseng’s whole form.
For whole powdered ginseng root, you can take up to 2 grams daily. Start with half a gram once or twice a day when you first start using ginseng, as it could potentially cause side effects. Potential side effects include mood changes, blood pressure changes, loss of appetite, insomnia, elevated heart rate, heart palpitations, menstrual irregularities, and more. Any herb can potentially cause an allergic reaction, so be sure to stop taking ginseng if you have any adverse effects.
Supplementing with Ginseng
There are many reasons ginseng has been highly revered as a staple in traditional systems of medicine. Ginseng can act as a natural remedy for low sex drive, it can help curb high blood sugar, boost mental performance and enhance energy. New research points to ginseng even protecting against cancer. To reap the benefits of ginseng, you can take a capsule supplement, drink ginseng tea or take a ginseng tincture.
It’s important to remember that even natural compounds can have unwanted side effects. To ensure your safety, it’s always a good idea to speak with a healthcare professional before taking herbal products or other supplements, particularly if you have medical conditions, are already taking medications or supplements, or are pregnant.
