Biological Activities
Panax ginseng contains a variety of bioactive compounds, including ginsenosides, polysaccharides, peptides, and polyacetylenes. These compounds contribute to its wide range of biological activities. For instance, ginsenosides are known to have anti-inflammatory, antioxidant, and anti-cancer properties1 4 9. Ginseng oligopeptides (GOPs), another component, have been shown to protect against liver damage induced by binge drinking through the inhibition of oxidative stress and inflammation1.
Health Benefits of Panax Ginseng
Cognitive Function
Panax ginseng has been shown to improve cognitive function. Studies have demonstrated that both Asian ginseng (Panax ginseng) and American ginseng (Panax quinquefolius) can enhance aspects of human cognitive function, such as working memory and reaction time2. The cognitive-enhancing properties are attributed to the distinct ginsenoside profiles found in these plants.
Physical Performance and Fatigue
Ginseng is also known for its ability to improve physical performance and reduce fatigue. Research has shown that supplementation with Panax ginseng can increase muscle mass, improve exercise performance, and decrease fatigue-associated parameters in both animal models and human subjects3 5 8. The underlying mechanisms include enhanced energy utilization and reduced oxidative stress.
Metabolic Health
Panax ginseng has shown promise in improving metabolic health. For example, fermented Panax ginseng has been found to ameliorate lipid metabolism disorders and modulate gut microbiota in rats fed a high-fat diet5. Additionally, American ginseng has been shown to improve glycemic control and cardiovascular risk factors in individuals with type 2 diabetes7.
Antioxidant Properties
The antioxidant properties of Panax ginseng have been well-documented. Clinical trials have shown that ginseng supplementation can significantly reduce levels of reactive oxygen species (ROS) and malondialdehyde (MDA) while enhancing the body’s antioxidant defense mechanisms9. These effects contribute to its potential in preventing oxidative stress-related diseases.
Hepatoprotection
Panax ginseng has also been studied for its hepatoprotective effects. It has been found to be superior to vitamin E in protecting against cyclophosphamide-induced liver damage in animal models. The protective effects are attributed to its ability to reduce oxidative stress and inflammation10.
Safety and Tolerability
Panax ginseng is generally considered safe for consumption. Clinical trials have shown that ginseng administration for up to four weeks is well-tolerated in healthy volunteers, with no serious adverse effects reported4. Mild side effects such as dyspepsia, hot flashes, insomnia, and constipation have been noted but are not significant enough to outweigh the benefits.

Adverse Effects of Panax Ginseng
Mild Adverse Effects
Panax ginseng administration has been associated with mild adverse events such as dyspepsia, hot flashes, insomnia, and constipation. These effects were reported in both the ginseng and placebo groups, indicating no significant difference1 3 5.
Cardiac Issues
High doses of Panax ginseng may cause cardiac damage, including diastolic dysfunction, heart failure with preserved ejection fraction, and reduction of blood pressure. Increased levels of cardiac biomarkers like troponin I and myoglobin were observed, along with histopathological changes in myocardial fibers2.
Gastrointestinal and Nervous System Symptoms
Gastrointestinal symptoms (e.g., dyspepsia) and nervous system-related symptoms were frequently reported in studies involving Panax ginseng, although these were not statistically significant compared to placebo3.
Liver Damage
Panax ginseng has shown hepatoprotective effects against certain types of liver damage, such as those induced by cyclophosphamide. However, it is important to note that the studies primarily highlight its protective rather than adverse effects on the liver6 9.
No Significant Adverse Effects in Specific Conditions
In patients with rheumatoid arthritis, Panax ginseng did not significantly increase the rate of adverse events or disease flare-ups, suggesting it is relatively safe in this population3.

How has Panax Ginseng Improved Patient Outcomes?
Cognitive Performance Improvement
Panax ginseng has been shown to enhance cognitive performance and reduce mental fatigue in healthy individuals during sustained mental tasks1 3.
In patients with Alzheimer’s disease, Panax ginseng improved cognitive performance as measured by MMSE and ADAS scales, although these improvements declined after discontinuation2.
Blood Glucose Regulation
Panax ginseng can reduce blood glucose levels in healthy individuals, suggesting glucoregulatory properties1 3.
American ginseng (Panax quinquefolius) significantly reduced HbA1c and fasting blood glucose levels in individuals with type 2 diabetes4.
Fatigue Reduction
Panax ginseng did not show significant superiority over placebo in reducing cancer-related fatigue, although both groups showed improvement5 9.
American ginseng showed trends towards reducing cancer-related fatigue, with higher doses (1,000-2,000 mg/day) showing more perceived benefits8.
Cardiovascular and Metabolic Health
American ginseng improved arterial stiffness and reduced systolic blood pressure in patients with type 2 diabetes and hypertension6.
It also lowered LDL cholesterol and improved the LDL/HDL ratio in individuals with type 2 diabetes4.
Fibromyalgia and Quality of Life
Panax ginseng reduced pain, fatigue, and improved sleep and quality of life in patients with fibromyalgia, although no significant differences were found compared to placebo or amitriptyline7.
In menopausal women, Panax ginseng improved sexual function, quality of life, and reduced menopausal symptoms10.

Panax Ginseng Mechanisms of Action
PI3K/Akt/mTOR Pathway Activation
Panax ginseng enhances physical recovery and energy utilization by activating the PI3K/Akt/mTOR signaling pathway, which is crucial for muscle glycogen sparing and promoting ATPase activities1.
AMPK Pathway Upregulation
It improves glucose metabolism in diabetic models by upregulating the AMP-activated protein kinase (AMPK) pathway, increasing insulin receptor and glucose transporter (GLUT-2) expression, and enhancing activities of glucose-manipulating enzymes2.
Muscle Excitation and Recovery
Panax ginseng increases muscle recruitment, reduces perceived effort, and accelerates muscle force recovery post-exercise by enhancing muscle excitation and reducing muscle damage markers3.
Gluco-regulatory Properties
It lowers blood glucose levels and improves cognitive performance during sustained mental activities, likely due to its gluco-regulatory properties4 7.
Oxidative Stress and Inflammation Inhibition
Ginseng oligopeptides protect against liver damage induced by binge drinking by inhibiting oxidative stress and inflammation through the toll-like receptor 4 and nuclear factor-κB signaling pathways5.
NLRP3 Inflammasome Suppression
The combination of Panax ginseng and Angelica sinensis alleviates ischemic brain injury by suppressing NLRP3 inflammasome activation and microglial pyroptosis, reducing inflammation and cell death6.
Lipid Metabolism Regulation
Fermented Panax ginseng ameliorates lipid metabolism disorders and modulates gut microbiota, reducing obesity and hyperlipidemia in high-fat diet models8.
Anti-Fatigue Effects
Ginseng oligopeptides exhibit anti-fatigue effects by enhancing lactate dehydrogenase activity, increasing hepatic glycogen levels, and improving mitochondrial function in skeletal muscles9.
Antioxidant Properties
Panax ginseng enhances antioxidant defense mechanisms by reducing reactive oxygen species and increasing glutathione levels in healthy subjects10.

Common Complaints Associated with Panax Ginseng Use
Mild Adverse Events
Common mild adverse events reported include dyspepsia, hot flashes, insomnia, and constipation. These effects were observed in both Panax ginseng and placebo groups, indicating they may not be solely attributable to ginseng1.
Cardiac Effects
Panax ginseng has been associated with cardiac issues such as reduced blood pressure, increased levels of cardiac biomarkers (troponin I and myoglobin), and diastolic dysfunction. These effects were more pronounced with higher doses and longer durations of use3.
Gastrointestinal Effects
Fermented ginseng has been shown to alleviate symptoms of antibiotic-associated diarrhea and colon inflammation in rats. However, excessively high or low doses were not beneficial, indicating a need for appropriate dosing2.
