For centuries, ginseng has been celebrated in traditional medicine as a natural “cure-all.” Known for its ability to boost energy, improve focus, and support overall well-being, this remarkable herb is now gaining attention in modern research for its potential role in protecting the brain and supporting healthy aging.
So how might ginseng benefit your brain and body?
Why Ginseng?
Of course, ginseng isn’t a “cure-all”, but it may have some benefit to our health. A growing body of evidence has revealed that the secret to ginseng’s power lies in its active compounds: ginsenosides and gintonin. These plant-based compounds are thought to reduce inflammation, combat oxidative stress, and support cell repair.
There are two main varieties of ginseng—Asian (Panax ginseng) and American (Panax quinquefolius)—each with slightly different effects. Asian ginseng, which is the focus of most studies, is believed to have a more invigorating effect, while American ginseng is considered calming.
However, not all ginseng supplements are created equal. A study analysing over 500 ginseng products found that nearly a quarter were tampered with or contained filler ingredients. When choosing ginseng, look for a trusted source that specifies the concentration of ginsenosides to ensure you’re getting a quality product.
How Ginseng Supports Brain Health
As we age, the brain becomes more vulnerable to damage from oxidative stress and inflammation, two key factors in the development of conditions like Alzheimer’s disease. While ginseng isn’t a cure, growing evidence suggests it can play a role in supporting brain health and memory.
1. Enhances Memory and Focus
Studies in animals and humans show that ginseng may boost memory and cognitive performance by protecting brain cells and encouraging the growth of new ones. For example, ginsenoside Rh1 has been shown to increase levels of brain-derived neurotrophic factor (BDNF)—a protein that helps neurons grow and thrive.
In animal studies, ginseng has also been found to reduce the buildup of amyloid plaques, a hallmark of Alzheimer’s disease, while improving neurotransmitter function. These effects may help explain why ginseng has long been used to support focus and learning.
2. Combats Oxidative Stress
The brain is highly sensitive to damage from free radicals, unstable molecules that can harm cells and accelerate aging. Ginseng’s antioxidants neutralise these harmful molecules, reducing inflammation and protecting brain tissue.
Even short-term use has shown benefits. In one study, 71 postmenopausal women who took 3 grams of ginseng daily for 12 weeks experienced significant reductions in oxidative stress markers.
3. May Improve Mood and Resilience
Ginseng isn’t just for memory—it may also help with mental well-being. Research suggests it can ease stress, reduce anxiety, and even improve symptoms of depression by modulating stress-related hormones and supporting overall brain function.
Everyday Benefits Beyond the Brain
While its impact on brain health is impressive, ginseng offers additional benefits that support your overall vitality:
-
Fights Fatigue: Ginseng is famous for its ability to combat tiredness. Studies suggest it boosts energy at a cellular level, helping you feel more alert and less fatigued throughout the day.
-
Strengthens Immunity: Ginseng is rich in compounds that support immune function, making it a great option for staying healthy during cold and flu season.
-
Balances Blood Sugar: Research shows ginseng can help regulate blood sugar levels, improving insulin sensitivity and supporting metabolic health.
Safety and Side effects
There have been a few clinical trials on the effect of ginseng. One placebo controlled trial looked specifically at the safety and tolerability of ginseng. Investigating the effects of 2g of Panax ginseng a day for 24 months reported that there are no adverse effects of ginseng and it is well tolerated.
How to Use Ginseng
Incorporating ginseng into your routine is simple. It’s widely available as capsules, powders, teas, or extracts. When selecting a supplement:
-
Look for a product that specifies the percentage of ginsenosides (ideally, somewhere around 4-7%).
-
Choose a brand that provides clear information about sourcing and purity.
As with any supplement, it’s a good idea to consult your doctor—especially if you’re on medications like blood thinners or have conditions like diabetes.
The Bottom Line
Ginseng isn’t just an ancient herbal remedy—it’s a modern-day tool for boosting brain health, energy, and resilience. While more research is needed to fully understand its effects, the evidence so far is promising.
