Benefits Of Ginseng On Brain and Memory Health

Ginseng and Cognitive Function

Ginsengs are known to have anti-inflammatory and antioxidant properties; hence, they are associated with cognitive function. Below are some benefits of ginseng for brain health:

Alleviate Anxiety and Depression

Ginseng is associated with reducing anxiety and depression. It helps maintain homeostasis by regulating immune response and hormonal change. Aside from alleviating psychological disorders like anxiety and depression, other benefits of ginseng for brain health include preventing physiological disorders caused by stress.

According to research published by Hou. W et al., 2020 in the Frontiers in Cellular Neuroscience, ginseng has an antidepressant effect that gives it the ability to act on neurotransmitters, hormones, and receptors.

Memory and Learning

A randomized, double-blind, placebo-controlled crossover trial Scholey, A. et al. (2010), conducted on 32 healthy individuals who were administered three doses (100, 200, and 400 mg) of standardized ginseng and measured at 1, 3, and 6 hours, concluded that oral administration of American ginseng helps enhance working memory.

In addition, another study involving 15 healthy young males divided the subjects into two groups, with 8 subjects receiving a daily dose of 4,500 mg red ginseng and 7 subjects on a placebo for two weeks. The red ginseng group is suggested to help improve cognitive health.

Reduce Cognitive Decline

According to a study by Lee, B. C., et al., ( 2023) published in Frontiers in Aging Neuroscience, involving 10 adults between 65–90 years with no dementia. All participants were subjected to comprehensive dietary and clinical assessments.

The study concluded that ginseng intake over a long period helps improve AD-specific cognitive decline, including delayed episodic memory.

Therefore, slowing down the progression of cognitive decline is one of the benefits of ginseng for brain health.

Protects Against Neurodegenerative Diseases

Neurodegenerative diseases, including Alzheimer's and Parkinson's, involve the gradual deterioration of brain cells, often due to the buildup of harmful proteins and chronic inflammation. Ginseng has shown promise in protecting the brain from such damage.

Studies suggest that ginseng's antioxidant and anti-inflammatory properties may help reduce the accumulation of these damaging proteins, promoting long-term cognitive health.

Increases Blood Flow to the Brain

One of the key benefits of ginseng is its ability to enhance blood circulation, including blood flow to the brain. Increased circulation ensures better delivery of oxygen and nutrients to brain cells, which can enhance cognitive functions such as concentration, focus, and mental clarity.

A study by Kim, C. S., et al., (2002) published in Acta Pharmacologica Sinica found that ginseng significantly improves cerebral blood flow, which supports optimal brain health and performance.

Can Ease Addiction Withdrawal

Addiction to substances such as alcohol or drugs can severely impact cognitive function, leading to impaired concentration and memory. Ginseng has been shown to help alleviate withdrawal symptoms, reducing anxiety and fatigue often experienced during recovery. It may also improve focus and clarity, aiding in the cognitive rehabilitation process.

Research by Shin, M. S., et al., (2024), published in the Journal of Ginseng Research indicates that ginseng helps restore brain function by enhancing neural plasticity and reducing stress-induced damage.

Increases Important Brain Chemicals

Ginseng helps regulate neurotransmitters like dopamine and serotonin, which are crucial for mood, focus, and cognitive function. By boosting the levels of these brain chemicals, ginseng supports a balanced and healthy brain, improving overall cognitive performance.

Studies in Basic and Clinical Neuroscience have demonstrated that ginseng can enhance the release of dopamine and serotonin, promoting mental well-being and optimal cognitive health.

Here’s a video of Dr. Patrick Jones discussing plants that support cognition, memory, and focus, including Ginseng.

Which Ginseng is Best for Memory?

One of the benefits of ginseng for brain health is improved memory. While different types of ginseng are useful for health purposes, two are mostly popular for brain function. The best ginseng for memory are Korean ginseng (Panax ginseng) and American ginseng (Panax quinquefolius).

Panax ginseng

Panax ginseng, also known as Asian or Korean ginseng, has existed for many years in Chinese Traditional Medicine as a treatment for different diseases. The major compounds found in Panax ginseng are ginsenosides. These compounds are known to have antidiabetic, antiallergic, anticancer, antioxidation, anti-inflammatory, and vasorelaxation effects.

In addition, Panax ginseng is known to help support brain function. The benefits of Panax ginseng for memory are a result of the compounds contained in it.

A randomized controlled trial published in the National Library of Medicine tested 4.5 g of Panax ginseng on 58 volunteers over 12 weeks, measuring cognitive performance with MMSE and ADAS. Results showed improved scores during treatment, but a decline after stopping. This suggests Panax ginseng may temporarily enhance cognitive performance in AD patients.

How to Take Panax Ginseng

The recommended dosage of Panax ginseng can vary depending on the individual and the specific health goal. However, a typical dosage recommended by the National Library of Medicine ranges from 200 to 600 mg per day of standardized extract. This is equivalent to 0.5 - 2 grams for short-term dosing and 1 gram for long-term dosing.

Start with a lower dose to assess your response. Available in capsules, tablets, teas, or liquid extracts, it’s best to consult a healthcare provider, especially if you’re on medications or have health conditions.

American ginseng

American ginseng, scientifically known as Panax quinquefolius, is native to North America, and it is a famous traditional medicine and healthy food that is always in high demand. American ginseng contains active compounds like ginsenosides, and saponins.

These compounds are present in the fruits, leaves, roots, and stems of the plant and also make it qualify as ginseng for brain health.

A randomized, double-blind, placebo-controlled, crossover trial published in the National Center for Biotechnology Information involving 32 healthy young adults investigated the acute mood, neurocognitive, and glycaemic effects of three doses of standardized Panax quinquefolius (100, 200, 400 mg). The result concluded that all three doses significantly improved working memory.

How to Take American Ginseng

American ginseng is typically taken in doses of 200 to 500 mg per day of standardized extract, either in one dose or split between morning and afternoon. It’s available in capsules, tablets, teas, and tinctures, and should be taken with food to prevent stomach discomfort.

Start with a lower dose and gradually increase. To avoid tolerance, cycle its use. Consult a healthcare provider if you have health conditions or take medications.

Side Effects and Precautions

Side Effects

• Common side effects include insomnia, nervousness, headaches, and stomach upset.
• Some people may experience dizziness, dry mouth, or allergic reactions.

Precautions:

• Consult a healthcare provider before using ginseng, especially if you have conditions like heart disease, diabetes, or high blood pressure.
• Ginseng may interact with medications such as blood thinners, insulin, or antidepressants.
• Avoid ginseng if pregnant or breastfeeding due to limited research on its effects.
• Individuals with autoimmune conditions should be cautious as ginseng may stimulate the immune system.
• Use ginseng in cycles to avoid tolerance.

Summary

Ginseng, whether American or Korean ginseng, has a lot of health benefits, and this is attributed to the compounds present in it. These compounds are antioxidant, anticancer, antidiabetic, and anti-inflammatory. In addition, the benefits of ginseng for brain health are also a result of these compounds.

Ginsengs are good for memory, learning, brain health, and overall improved cognitive health. Different clinical, pre-clinical and randomized controlled trials have proved these benefits. Therefore, ginseng is an ideal option if you are looking for a supplement for brain health.
