What Is Ginseng?
Ginseng, translating to "essence of man" in Chinese, is a renowned adaptogenic herb in traditional medicine, used to support energy and physical stamina. It is derived from the roots of plants belonging to the Panax genus. Within the ginseng family, various species exist, each with distinct characteristics. Asian ginseng (Panax ginseng) and American ginseng (Panax quinquefolius) stand out as the most widely utilized and extensively researched varieties. These plants possess unique chemical compositions, making them valuable in traditional and modern medicine practices. (1, 4)Β
One of the key components contributing to ginseng's medicinal properties is ginsenosides, a class of natural compounds called triterpene saponins found in the plant's roots. Evidence supports the anti-inflammatory, antioxidant, and anticancer effects of ginsenosides. The content and types of ginsenosides vary among different ginseng species, influencing their specific medicinal effects and deriving unique characteristics amongst the various species of ginseng plants. American and Asian ginseng are both utilized to enhance energy levels, boost cognitive function, alleviate stress, and support the immune system. In traditional Chinese medicine (TCM), Asian ginseng is considered warm and stimulating, whereas American ginseng is cool and calming.Β
The Top 4 Therapeutic Uses of Ginseng
Taken orally, ginseng is promoted as a tonic to support overall well-being and increase resilience to stress. Evidence supports its use for various other reasons, including modulating the immune system, supporting cardiovascular health, and improving physical and mental stamina. (3)
1. Cognitive Enhancement and Mental Well-Being
Ginseng has garnered significant attention for its therapeutic effects in supporting brain health and mental clarity. Several research findings suggest that ginseng may have positive impacts on cognitive function. Clinical studies have demonstrated that ginseng supplementation can enhance cognitive performance by reducing neurological oxidative stress. It is believed that ginsenosides and compound K are crucial in ginseng's promotion of cognitive function, which encompasses thinking, communication, understanding, and memory. In controlled trials, patients who have consumed ginseng supplements exhibit enhanced working memory, reduced Alzheimer's disease symptoms, and improved cognitive function later in life. (18)Β
Moreover, ginseng's adaptogenic properties are thought to help the body manage stress, which can contribute to improved mental well-being. In one study, Panax ginseng supplementation reduced circulating cortisol (the body's stress hormone) in response to physical stress.Β
Researchers have also explored its potential in mitigating symptoms of anxiety and depression, with some studies indicating a positive impact on mood regulation.
2. Immune System Boosting Properties
Ginseng's reputation as an immune system booster is supported by a large body of evidence that has explored ginseng's immunomodulatory effects. These effects are attributed to ginsenosides, polysaccharides, and other bioactive compounds in ginseng roots. (33)Β
Several studies have demonstrated that ginseng supplementation can stimulate the production and activity of immune cells, such as macrophages and T lymphocytes, which are vital components of the immune system. A clinical study with 100 participants showed that patients taking 2 grams of Asian ginseng daily for two months had significantly increased levels of immune cells at the end of the trial compared to those taking a placebo. Ginsenosides, in particular, have been shown to enhance the body's defense mechanisms by improving the phagocytic activity of immune cells and increasing the production of cytokines, signaling molecules that regulate immune responses. (33)Β Β
This modulation of immune function contributes to ginseng's ability to help the body ward off infections and cancers. Several studies have shown the benefits of strengthening immunity with ginseng to prevent and treat infections. For example, a study of 227 healthy volunteers demonstrated that daily supplementation of 100 mg of ginseng extract for three months increased the efficacy of the influenza vaccine. Participants taking ginseng had a lower incidence of cold and flu, higher antibody titers, and a higher level of natural killer cell activity. Another study demonstrated that ginseng is an effective adjunct to antibiotics for quickly clearing bacteria in patients with bronchitis.
3. Energy and Stamina Enhancement
Ginseng has long been recognized for its potential to enhance energy levels and stamina, and numerous clinical studies have provided evidence supporting its therapeutic effects in this domain. These studies have often involved athletes and individuals engaged in high-intensity physical activities. Such trials have demonstrated mixed results, with some showing ginseng having no effect on physical performance and others showing supplementation improves aerobic exercise performance and endurance.
Ginseng's adaptogenic properties are believed to help the body adapt to physical stressors and reduce feelings of fatigue and exhaustion. A 2018 systematic review concluded that both American and Asian ginseng are viable treatment options for fatigue in people with chronic illnesses. For example, women with multiple sclerosis taking Panax ginseng in a dose of 250 mg twice daily for three months experienced a 75% reduction in fatigue and a significant improvement in overall quality of life. Another clinical trial found that taking Panax quinquefolius in a dose of 1,000 mg twice daily for two months improves cancer-related fatigue scores by 51%.
Researchers have postulated that ginseng's anti-fatigue effects stem from the ginsenosides' antioxidant properties and their ability to enhance mitochondrial function.
4. Cardiovascular Health and Blood Sugar Regulation
Ginseng has emerged as a promising natural remedy for promoting cardiovascular health and managing blood sugar levels, with clinical studies offering valuable insights into its therapeutic effects in these areas. Evidence supports ginseng's potential to lower blood pressure, improve blood circulation, and reduce risk factors associated with cardiovascular diseases.
Several trials have explored the impact of ginseng on blood pressure regulation, indicating that regular ginseng supplementation can lead to modest reductions in both systolic and diastolic blood pressure. These effects are believed to be mediated through the relaxation (vasodilation) of blood vessels and the promotion of vascular endothelial cell-derived nitric oxide secretion (22). Additionally, ginseng has been shown to have anti-inflammatory and antioxidant properties, which are beneficial for overall cardiovascular health.
Using ginseng for blood sugar balance has also been supported by clinical studies, which have highlighted ginseng's ability to improve insulin sensitivity and regulate glucose metabolism. Ginsenosides, through their interaction with insulin receptors, help enhance the body's response to insulin, thereby promoting better blood sugar control (33). This effect has been observed in individuals with type 2 diabetes as well as those at risk of developing the condition. Studies have reported reductions in fasting blood glucose levels and improvements in long-term glucose control markers among ginseng users (28, 32).Β
Safety, Dosage, and Consumption
Ginseng is commonly available in capsule or tablet form, standardized to ginsenoside content. Studies have shown that oral use of ginseng in doses varying from 200mg to 3 grams daily for up to six months is safe. There is little scientific data to support its safety when used for more extended periods. The most commonly reported side effect of ginseng is insomnia. Other potential side effects of ginseng include menstrual changes, breast pain, changes to blood pressure and blood sugar, headache, and digestive symptoms. (3, 13, 27)
Ginseng may interact with other medications. Before taking ginseng, consult a healthcare provider if you are taking digoxin, diuretics, MAOI antidepressants, antihypertensive medications, and warfarin. (3, 13, 27)
