A Beginner's Guide to Ginkgo Biloba as a Natural Nootropic

 

 

What is Ginkgo Biloba? 

Ginkgo biloba is known as the maidenhair tree which is celebrated as the oldest living tree species. Originating in the Permian period, approximately 286 to 248 million years ago, it is the sole survivor of the Ginkgoaceae family, which once flourished globally.

The species' remarkable survival is due to its exceptional adaptability and resistance to disease, alongside the preservation efforts of Buddhist monks who cultivated these trees within their temple grounds.

Renowned for its medicinal properties and historical significance, Ginkgo biloba is extensively studied and utilized in modern herbal supplementation.

The leaves and seeds are harvested for their health-promoting bioactive compounds, which have been the subject of extensive research. These compounds are explored for their potential in enhancing cognitive function, supporting neurogenesis, and providing neuroprotective effects against various neurological conditions.

Chemical Composition 

The chemical composition of Ginkgo biloba includes a rich array of bioactive compounds, primarily found in its seeds and leaves, that contribute to its wide range of medicinal benefits.

These active constituents include minerals, flavonoids, triterpene lactones, phenolic compounds, ginkgotoxin (4-O-methylpyridoxine), ginkgolic acid, and ginnol, which are known to inhibit the growth of fungi and bacteria.

Among these, flavone glycosides, biflavones, triterpene lactones such as ginkgolides A, B, C, J, M, and bilobalide, alkylphenols, proanthocyanidins, polyprenols, phenolic acids, 6-hydroxykynurenic acid, and ginkgotoxin are predominantly found in the leaves​​.

Ginkgolides, unique to Ginkgo biloba, are a set of trilactonic diterpenes (ginkgolides A, B, and C), contributing to the plant's potent anti-inflammatory, neuroprotective, and circulatory benefits.

These compounds have been specifically shown to act as platelet-activating factor (PAF) antagonists, thereby inhibiting platelet aggregation and enhancing blood flow.

Flavonoids in Ginkgo biloba, including quercetin, kaempferol, and isorhamnetins, are major antioxidants that play a critical role in scavenging free radicals and acting as heavy metal chelators due to their phenolic structures.

These flavonoids, along with proanthocyanidins and various organic acids such as glucose, rhamnose, hydroxykynurenic, kynurenic, protocatechuic, vanillic, and shikimic acids, form the pharmacologically active base of Ginkgo biloba extracts​​.

Historical Context and Traditional Uses

Characterized by its unique, fan-shaped leaves that turn a vibrant yellow in autumn, Ginkgo biloba is both a symbol of beauty and a repository of ancient genetic heritage.

The Ginkgo tree, with its distinctive foliage, not only captivates the eye but also holds a revered place in traditional Chinese medicine. For nearly 5000 years, it has been utilized for a variety of health concerns, most notably asthma.

Ginkgo biloba's resilience is not just limited to its biological and health-related attributes.

The tree has an extraordinary ability to resist disease, pollution, and environmental stress, which has allowed it to survive through epochs and become a celebrated ornamental species around the world. Its nuts are considered a delicacy in many cultures, while the leaves are used in traditional medicine to treat various ailments, from cognitive disorders to cardiovascular issues.

In modern times, Ginkgo biloba has found its way into the heart of alternative medicine, particularly as a dietary supplement aimed at improving memory and concentration, reducing symptoms related to dementia, and enhancing overall mental clarity and well-being.

The standardized extract of Ginkgo biloba leaves, known as EGb 761, has been the subject of numerous scientific studies exploring its efficacy in treating and managing a wide range of health issues, from cognitive impairments and dementia to peripheral vascular diseases and neurosensory problems.

 

 

Ginkgo Biloba as a Nootropic

Understanding Nootropics

Nootropics, often referred to as "smart drugs" or cognitive enhancers, are substances that improve cognitive function, particularly executive functions, memory, creativity, or motivation, in healthy individuals. The term "nootropic" was coined in the 1970s by Romanian psychologist and chemist Dr. Corneliu E. Giurgea, who defined nootropics as compounds that enhance learning and memory, protect the brain against physical or chemical injuries, and possess few or no side effects.

Nootropics can be broadly categorized into two groups: natural and synthetic. Natural nootropics, such as Ginkgo biloba, Bacopa monnieri, and Rhodiola rosea, are derived from plants and have been used in traditional medicine for centuries. Synthetic nootropics, such as Piracetam and Modafinil, are man-made compounds developed to enhance cognitive function and are often used in clinical settings to treat various neurological conditions.

The primary benefits of nootropics include enhanced memory, improved focus and attention, increased mental energy, and better mood. These effects are achieved through various mechanisms, such as increasing the availability of neurotransmitters, improving cerebral blood flow, and providing neuroprotection.

 

Cognitive Decline

Cognitive decline is a major concern for aging populations, and researchers are exploring various ways to slow it down. One promising option is Ginkgo biloba extract (GBE). Numerous studies have looked into how effective GBE is in slowing cognitive decline, especially in elderly individuals who do not have dementia.

One notable study by Amieva et al. (2013) tracked the long-term effects of GBE on brain function. This study, part of the PAQUID project, followed 3,612 people aged 65 and older for 20 years. The participants were divided into three groups: 589 people who used GBE (EGb761H), 149 who used another drug called piracetam, and 2,874 who used neither.

The researchers measured cognitive decline using several tests, including the Mini-Mental State Examination (MMSE), verbal fluency tests, and the Benton Visual Retention Test (BVRT). They used a detailed statistical model to analyze the data.

The study found that those who took GBE had significantly slower cognitive decline compared to those who did not take it. Specifically, the GBE group had a slower decrease in their MMSE scores, with an average difference of 0.5 points per follow-up visit over 20 years. By the end of the study, the GBE group had a five-point advantage in MMSE scores compared to the control group. On the other hand, the group taking piracetam experienced faster cognitive decline than both the GBE group and the control group.

When it came to verbal fluency and visual memory, the GBE group did not show significant differences compared to the control group, while the piracetam group showed a greater decline. This suggests that GBE specifically benefits overall cognitive function rather than specific areas of cognition.

The protective effects of GBE come from its various actions. It acts as an antioxidant, reduces inflammation, and prevents cell death. GBE also helps reduce the buildup of harmful amyloid-beta proteins, protects energy-producing parts of cells (mitochondria), improves neurotransmission, and boosts blood flow and microcirculation in the brain. All these effects together help preserve cognitive functions in older adults.

Additionally, GBE's role in reducing the need for psychotropic drugs, like antidepressants and antipsychotics, supports its benefits for cognitive health. The study found that people using GBE were less likely to need these medications, which can negatively impact cognitive function.

 

Neurogenesis

Neurogenesis, the creation of new neurons in the brain, is essential for maintaining cognitive functions and overall brain health. This process is severely disrupted in neurodegenerative diseases like Alzheimer’s disease (AD). Recent research has shown that Ginkgo biloba extract (EGb 761) may enhance neurogenesis and reduce cognitive decline linked to such diseases.

A key study by Ge et al. (2021) investigated how different doses of EGb 761 affect neurogenesis and memory in a mouse model of AD. The study involved daily injections of EGb 761 at doses of 0, 10, 20, and 30 mg/kg over four months. Researchers examined the effects on learning and memory, amyloid-beta (Aβ) pathology, and neurogenesis in the hippocampus, a brain region crucial for memory.

The findings revealed that doses of 20 and 30 mg/kg of EGb 761 significantly improved memory in the AD mice. Tests like the Morris Water Maze and novel object recognition showed that treated mice had better spatial memory and recognition abilities compared to untreated mice.

Additionally, the study found that EGb 761 reduced the number of Aβ positive signals in the hippocampus, which are indicators of AD pathology. The treatment also boosted the number of new neurons and enhanced the complexity and connectivity of neurons in the hippocampus. Specifically, there were more BrdU-positive cells, which mark new neuron formation, in the EGb 761 treated mice than in the untreated ones. This suggests that EGb 761 promotes the growth of new neurons, contributing to better cognitive functions.

 

Cognitive Impairment

Cognitive impairment and dementia, including Alzheimer's disease (AD) and vascular dementia (VaD), are serious health issues affecting millions of people worldwide. Researchers are looking into Ginkgo biloba, a traditional herbal remedy, to help manage these conditions.

A large analysis by Hashiguchi et al. (2015) reviewed 13 studies involving 2,381 patients. It found that Ginkgo biloba extract (EGb761) significantly improved cognitive function. Patients taking a daily dose of 240 mg showed substantial improvements in their cognitive scores, specifically in the Syndrome Kurztest (SKT), a test for cognitive abilities. The improvement was measured as a standard mean difference (SMD) of -0.71, indicating a strong benefit, especially for those with AD and VaD.

Ginkgo biloba is also safe to use. The analysis showed fewer patients stopped taking it due to side effects compared to those taking a placebo (dummy treatment). The odds ratio was 1.72, meaning those on Ginkgo biloba were less likely to drop out. Common side effects like headaches and dizziness were rare and similar to those in the placebo group. This suggests Ginkgo biloba is both effective and safe, particularly at the 240 mg daily dose, for improving cognitive function in affected individuals.

Another review by Tan et al. (2015) looked at nine trials with 2,561 patients. It confirmed that standardized Ginkgo biloba extract (EGb761) improved cognitive function, daily living activities, and overall clinical outcomes compared to placebo. The improvement in cognitive scores was particularly significant at a daily dose of 240 mg, with a weighted mean difference (WMD) of -2.86.

Moreover, EGb761 was especially beneficial for patients with neuropsychiatric symptoms (NPS), such as mood disturbances. These patients showed greater improvements in daily activities and cognitive function, with a WMD of -3.95 for ADAS-cog scores, another cognitive test. Safety data indicated no major concerns, with minor side effects like dizziness and headaches occurring less frequently in the EGb761 group compared to placebo.

 

 

Scientific Evidence on Ginkgo Biloba's Benefits

Neurological Disorders

Neurological disorders include a variety of conditions affecting the nervous system, such as Alzheimer's disease (AD), vascular dementia (VaD), and behavioral and psychological symptoms of dementia (BPSD). Recent clinical guidelines and studies have shown that Ginkgo biloba extract (EGb 761®) may help manage these conditions. Clinical trials have found that EGb 761® can improve cognitive function in patients with mild to moderate dementia.

One key study by Le Bars and colleagues involved 236 patients with uncomplicated dementia who took 120 mg/day of EGb 761® for a year. They used two main tests to measure results: the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) and the Geriatric Evaluation by Relative’s Rating Instrument (GERRI). The study found significant improvements in both tests, showing that EGb 761® helped improve cognitive function in these patients (Le Bars et al., 1997).

Another study tested 156 dementia patients who took 240 mg/day of EGb 761® for 24 weeks. Results were measured using the Syndrom Kurz Test (SKT), Clinical Global Impressions (CGI), and Nüberger Alters-Beobachtungsskala (NAB). This study also found significant improvements, indicating EGb 761®'s effectiveness in boosting cognitive performance in dementia patients (Kanowski et al., 1997).

In a study with 395 outpatients with AD or VaD, patients took 240 mg/day of EGb 761® for 22 weeks. Researchers used the Neuropsychiatric Inventory (NPI), SKT, and activities-of-daily-living subscale of Gottfries–Bråne–Steen (GBS-ADL) to measure results. Significant improvements were seen in all tests, confirming the positive effects of EGb 761® on cognitive function and daily activities (Napryeyenko et al., 2007).

Ihl and colleagues studied 327 outpatients taking 240 mg/day of EGb 761® for 24 weeks. They used several tests, including SKT, NPI, and Verbal Fluency Test, and found significant improvements, supporting EGb 761®'s efficacy in treating dementia with neuropsychiatric symptoms (Ihl et al., 2011).

In another 24-week trial with 402 elderly patients, EGb 761® was given at a dose of 240 mg/day. Cognitive function was assessed using SKT, NPI, and ADCS-CGIC, and significant improvements were observed in all areas, further validating the cognitive benefits of EGb 761® in elderly dementia patients (Herrschaft et al., 2012).

These studies suggest that taking 240 mg/day of EGb 761® for more than 24 weeks can significantly improve cognitive function in patients with mild to moderate AD or VaD. The clinical evidence supports the use of EGb 761® as a treatment option for managing cognitive decline in neurological disorders (Liu et al., 2020).

 

Blood Flow and Circulation

A pilot study by Mashayekh et al. (2011) looked at how Ginkgo biloba extract (EGb 761®) affects blood flow in the brain. The study involved nine healthy men, around 61 years old, who took 60 mg of EGb 761® twice a day for four weeks. Using advanced brain imaging techniques, the researchers found a slight increase in blood flow in a specific brain region and a significant overall increase of 15% in white matter and 13% in gray matter. This suggests that EGb 761® can boost blood flow to the brain, potentially helping conditions that affect brain circulation.

Boelsma et al. (2004) conducted a study to see how EGb 761® impacts blood flow in the skin. The study involved 27 healthy middle-aged people who took 240 mg of EGb 761® or a placebo for three weeks. Using laser technology to measure skin blood flow, they found that while the average skin blood flow decreased with EGb 761®, the changes were related to initial blood flow levels. This means that EGb 761® helps regulate blood flow, which could be useful for conditions needing stable blood flow.

Wu et al. (2007) studied the effects of EGb 761® on blood flow in the heart for patients with coronary artery disease (CAD). In this trial, 80 patients received either EGb 761® or a saline solution. Using ultrasound, the researchers measured blood flow in a major heart artery and the brachial artery. They found significant increases in heart artery blood flow and improved artery dilation in the EGb 761® group compared to the control group. Specifically, the peak blood flow velocities increased by 16.14% and 9.14%, and overall blood flow improved by 15.23%. Additionally, artery dilation improved by 69.75%. These results indicate that EGb 761® enhances heart blood flow and artery flexibility, which may benefit heart health and reduce the risk of heart problems.

  

Neurotransmitter Release

A study by Yoshitake et al. (2010) looked at how Ginkgo biloba extract (EGb 761®) affects key brain chemicals like dopamine, noradrenaline, and serotonin. Researchers gave rats 100 mg of EGb 761® per kilogram of body weight each day for 14 days. They found that this treatment significantly boosted levels of dopamine and noradrenaline in the prefrontal cortex, a part of the brain important for thinking and decision-making. Serotonin levels, however, were not affected. The increase in dopamine was mainly due to specific components in EGb 761® called flavonoids and ginkgolides. This suggests that EGb 761® might improve cognitive functions by raising dopamine levels in the brain.

Kehr et al. (2012) studied the effect of EGb 761® on dopamine and acetylcholine levels in another brain region called the medial prefrontal cortex. Rats received either 100 or 300 mg of EGb 761® per kilogram of body weight daily for 14 days. The researchers found that this repeated treatment significantly increased dopamine levels and also moderately boosted noradrenaline levels, without changing serotonin levels. They pinpointed that specific flavonol glycosides in the extract, particularly compounds named Q-ag and K-ag, were responsible for the rise in dopamine and acetylcholine. This indicates that these specific components of EGb 761® are crucial for improving cognitive functions by increasing both dopamine and acetylcholine levels.

Fehske et al. (2009) explored how EGb 761® influences the uptake of neurotransmitters in the brain. Mice were given 100 mg of EGb 761® per kilogram of body weight daily for 14 days. The study showed that EGb 761® significantly reduced the uptake of norepinephrine in the brain, which means more of this neurotransmitter remained available. However, it did not affect serotonin uptake or the activity of an enzyme that breaks down neurotransmitters (monoamine oxidase). Since dopamine clearance in the brain's frontal cortex relies on norepinephrine transporters, this reduction in norepinephrine uptake helps explain the increased dopamine levels found in earlier studies. This mechanism likely contributes to EGb 761®'s positive effects on cognition and attention.

 

 

Health Benefits Beyond Cognition

Antioxidant

The main active ingredients in Ginkgo biloba that make it effective are flavonoids and terpenoids. These substances help by neutralizing harmful free radicals and binding to metal ions that can promote oxidation (Singh et al., 2019).

Ginkgo biloba extract (GBE) works as an antioxidant by reducing oxidative stress, which is linked to diseases like Alzheimer's. The flavonoids in GBE, including quercetin and myricetin, are crucial for neutralizing harmful reactive oxygen species (ROS) and boosting the activity of antioxidant enzymes like superoxide dismutase (SOD) and glutathione (GSH) reductase (Singh et al., 2019).

Lab studies have shown that GBE can significantly reduce oxidative damage caused by hydrogen peroxide in brain cells (Ni et al., 1996; Oyama et al., 1996). In animal studies, GBE increased the activity of antioxidants like SOD and catalase, suggesting it strengthens the body's own antioxidant defenses (Bridi et al., 2001; Colak et al., 1998).

GBE protects the brain through several mechanisms. It reduces oxidative stress by directly neutralizing ROS and by increasing the production of antioxidant molecules. Studies on models that mimic Alzheimer’s, like certain worms and cell lines, have shown that GBE lowers both normal and increased levels of ROS (Wu et al., 2006; Smith and Luo, 2004). Additionally, GBE improves mitochondrial function, helping maintain cell energy and reducing oxidative damage (Rhein et al., 2010).

The flavonoids in GBE are also effective at binding to iron. This is important because iron can lead to the creation of highly reactive hydroxyl radicals. This binding ability helps prevent the formation of amyloid-beta fibrils, which are associated with Alzheimer’s disease (Smith et al., 2003; Ramassamy, 2006).

 

Anti-Inflammatory

The anti-inflammatory effects of Ginkgo biloba extract (GBE) are mainly due to its ability to control important inflammation pathways and lower the levels of substances that cause inflammation. GBE contains flavonoids and terpenoids, which are powerful anti-inflammatory agents. These substances stop the NF-κB pathway, a major player in inflammation, from being activated. This results in lower levels of inflammatory substances like TNF-α, IL-1β, and IL-6 (Kaur et al., 2018).

Kaur et al. (2018) studied how GBE protects against brain damage in rats caused by a toxin called trimethyltin (TMT). They found that GBE significantly improved brain function and reduced markers of oxidative stress, such as MDA and ROS. Additionally, GBE reduced the activation of brain cells and inflammatory markers elevated by TMT. The study showed noticeable improvement in brain cell damage, highlighting GBE's anti-inflammatory and antioxidant properties.

Another study by Kotakadi et al. (2008) found that GBE (EGb 761) helps reduce colitis (inflammation of the colon) in mice. It did this by causing the death of certain T cells that promote inflammation. EGb 761 also reduced the activation of macrophages and lowered inflammation markers like iNOS, Cox-2, and TNF-α. This supports using GBE to help manage colitis and potentially lower the risk of related colon cancer.

Zhu et al. (2019) looked at GBE's anti-inflammatory properties in lung diseases. They found that biflavones in the extract were the main anti-inflammatory agents. These biflavones significantly reduced inflammation markers and activity in lung cells and an allergic mouse model. This suggests that GBE can be a useful treatment for airway inflammation.

Zhang et al. (2022) examined the effects of GBE on heart and brain inflammation in rats on a high-fat diet and under chronic stress. Over 13 weeks, GBE significantly reduced inflammation in the heart and oxidative stress in the brain. The protective effects were linked to the inhibition of the NF-κB pathway, reducing inflammation markers in heart and brain tissues. GBE also improved overall immunity and increased anti-inflammatory cytokines like IL-37 and IL-38, showing its broad anti-inflammatory potential.

 

Anti-Aging

Aging is a natural process that affects our bodies and minds in various ways. However, there are ways to help reduce some of the negative effects of aging. One promising approach involves using herbal remedies like Ginkgo biloba (GB). This section looks at how Ginkgo biloba can improve the overall well-being of older adults, based on findings from multiple studies.

Researchers have conducted several studies to see if Ginkgo biloba can help improve cognitive functions (like memory and thinking skills) and overall well-being in older people. The main goal was to find out if GB could be a useful addition to treatments for age-related issues like Alzheimer's disease, heart disease, and metabolic disorders.

The research methods included different types of studies, such as randomized controlled trials (RCTs), systematic reviews, and meta-analyses. For example, a review by Barbalho et al. (2022) looked at results from 14 clinical trials where GB was given to elderly participants. These studies often compared GB with a placebo to see if it improved memory, thinking skills, and quality of life.

The results showed that Ginkgo biloba could improve various cognitive functions, including memory, decision-making, attention, and mood. In clinical trials, people with mild cognitive impairment and Alzheimer's disease saw significant improvements in memory and overall thinking skills after taking GB. These benefits are thought to come from GB's antioxidant, anti-inflammatory, and brain-protective properties, which help reduce damage from oxidative stress and improve blood flow in the brain.

Ginkgo biloba also helps cardiovascular health by improving blood circulation and slowing down the development of artery-clogging plaques. Studies have shown that GB can lower blood pressure, reduce fasting blood sugar levels, and decrease markers of oxidative stress and inflammation, all of which are important for maintaining heart health in older adults.

Additionally, Ginkgo biloba has shown potential benefits for metabolic health. It can help manage insulin resistance, lower body mass index (BMI), and reduce waist size. The active compounds in GB, such as flavonoids and terpenoids, play a key role in improving metabolic functions and overall health.
