Ashwagandha: Overview and History

Ashwagandha UK

Ashwagandha, scientifically known as Withania somnifera and belonging to the nightshade family Solanaceae, has been a cornerstone of Ayurvedic medicine for over 6000 years. It is often referred to as ‘Indian Winter cherry’ or ‘Indian Ginseng’, reflecting its place of origin.

Traditionally, Ashwagandha has been used as an important health tonic for all ages, as well as being considered an aphrodisiac. Its uses extend to various forms of traditional medicine, including Indian, Chinese, and Arabic practices.

Today, whether in the form of ashwagandha root powder, capsules, or extract, this versatile herb continues to be a fundamental part of herbal supplements and medicines across the globe.

Active Compounds of Ashwagandha Root

The secret to Ashwagandha’s myriad of health benefits lies in its active compounds. The ashwagandha root contains glycowithanolides, alkaloids, and steroidal compounds, which collectively contribute to its potential health benefits.

Sitoindosides, a form of saponins found in both the roots and leaves of ashwagandha, act as anti-stress agents, further adding to the herb’s potential therapeutic value.

These compounds work synergistically to provide the following potential health benefits of ashwagandha:

  • Reducing stress and anxiety
  • Improving sleep quality
  • Boosting immune function
  • Enhancing cognitive function
  • Increasing energy levels

The Adaptogenic Properties of Ashwagandha

Ashwagandha is recognised for its adaptogenic properties, which help the body manage stress and promote overall health.

Adaptogens are substances that help the body adapt to stress, whether physical, chemical, or biological, and restore normal physiological functions.

Numerous studies have indicated that ashwagandha root extract may have the following benefits:

  • Significantly reduces serum cortisol levels, demonstrating its role in improving resistance to stress
  • Prevents fluctuations in cortisol and ascorbic acid in the adrenal glands
  • Protects against gastrointestinal ulcers caused by stress

These findings highlight the adaptogenic activity of ashwagandha and its potential in promoting overall well-being.

Withanolides and sitoindosides, key constituents of ashwagandha, are linked to these anti-stress and adaptogenic effects, suggesting their role in combating oxidative stress and enhancing health resilience.

These adaptogenic properties make Ashwagandha an important herb in managing stress-induced diseases and helping to relieve general day-to-day stress.

Boosting Cognitive Function and Mental Health

Ashwagandha is traditionally believed to enhance cognitive functions and improve memory. This claim is supported by research demonstrating improvements in:

  • Executive functioning
  • Attention
  • Reaction time
  • Overall cognitive task performance

This makes Ashwagandha a significant part of the daily regimen for many looking to boost their cognitive function and mental alertness through incorporating ashwagandha powder into their routines.

The Mimetism of neurotransmitter GABA by Ashwagandha suggests significant benefits for the nervous system, potentially stabilizing mood along with reducing anxiety and depression.

Ashwagandha’s GABA mimetic effects may contribute to its calming impact on the nervous system, which has been associated with mood regulation and mitigating symptoms of anxiety.

Interestingly, studies point to Ashwagandha’s ability to enhance memory and learning, with the root extract specifically linked to improvements in both areas.

Research indicates that Ashwagandha may reduce depressive symptoms and aid cognitive impairment in individuals with mental health conditions such as bipolar disorder.

Enhancing Physical Performance and Energy Levels

Ashwagandha is not just a mental stimulant; it has physical benefits too. Elite cyclists exhibited increased cardiorespiratory endurance through improved VO2 max and time to exhaustion with Ashwagandha supplementation.

This finding underscores the impact of Ashwagandha in enhancing physical performance and promoting physical and mental health.

Additionally, Ashwagandha has been demonstrated to enhance stamina and endurance, as evidenced by increased swimming time in physical endurance tests with rats.

These results suggest that Ashwagandha can significantly boost energy levels and physical performance, making it a valuable supplement for those aiming to improve their physical health.

The ergogenic effects of Ashwagandha, such as enhanced physical performance, may be partly due to its potential to increase red blood cell count and hemoglobin levels.

This suggests that Ashwagandha can boost the body’s ability to transport oxygen, thereby improving stamina and endurance.

Ashwagandha’s Role in Immune System Support

Ashwagandha supports immunomodulatory actions, beneficial for strengthening the immune system. An immunomodulator is a substance that helps regulate or normalize the immune system, ensuring it functions optimally.

Ashwagandha can act as an immunomodulator and potentially enhance life span by improving immune function. This makes Ashwagandha a potentially beneficial supplement for those with weakened immune systems or those looking to boost their immune health.

However, it’s worth noting that individuals with autoimmune diseases, such as multiple sclerosis, lupus, and rheumatoid arthritis, should use Ashwagandha with caution as it can stimulate the immune system and potentially worsen symptoms.

As always, it’s important to consult with a healthcare professional before starting any new supplement regimen.

Anti-Inflammatory and Pain-Relief Benefits

Ashwagandha has been historically used in traditional medicine for its anti-inflammatory properties, credited to components such as withaferin A.

Inflammation is the body’s natural response to injury or illness, but chronic inflammation can lead to various health problems such as:

  • Heart disease
  • Diabetes
  • Arthritis
  • Alzheimer’s disease
  • Depression
  • Obesity

Clinical trials have demonstrated that ashwagandha can provide pain relief, especially when used consistently over a period of two to three months.

Moreover, Ashwagandha has been found to be useful in the clinical management of Rheumatoid Arthritis by exerting an anti-inflammatory effect and inhibiting glycosaminoglycan synthesis.

The pharmacological actions of ashwagandha, including neuroprotective, anti-stress, analgesic, and anti-inflammatory effects, contribute to its pain-relieving properties.

Neuroprotective Effects and Potential Applications

Preclinical studies and some clinical trials have established that ashwagandha possesses neuroprotective properties, potentially offering benefits for Alzheimer’s, Huntington’s, and Parkinson’s disease.

A neuroprotective substance is one that protects nerve cells against damage, degeneration, or impairment of function.

Ashwagandha’s neuroprotective effects are achieved through the restoration of mitochondrial and endothelial function, reduction in neural apoptosis, inflammation, and mitigation of oxidative stress.

Withanolide A, an active compound in Ashwagandha, can cross the blood-brain barrier, suggesting it may provide direct neuroprotective benefits inside the brain.

Ashwagandha has been shown to be potentially effective in the treatment of diseases such as Parkinson’s and Alzheimer’s due to its properties that inhibit the activity of enzymes responsible for harmful protein aggregates.

Continued administration of Ashwagandha has led to observed recovery in neurites and synapses, which are vital to cognitive functions and neuronal health.

Ashwagandha’s Antioxidant Capabilities

Ashwagandha contains natural antioxidants which can help prevent cell damage by neutralizing free radicals.

Free radicals are unstable molecules that can damage cells, leading to ageing and diseases. Antioxidants can neutralize these free radicals, helping to maintain the health and integrity of cells.

Ashwagandha contains potent antioxidant properties that aid in safeguarding cells from harm inflicted by free radicals. This means that Ashwagandha could potentially help to slow down the ageing process and reduce the risk of various diseases.

Ashwagandha extract has demonstrated antioxidant properties, significantly reducing free radical generation and potentially modulating cholinergic transmission. As such, the antioxidant capabilities of Ashwagandha serve as another testament to its immense potential health benefits.

Choosing the Right Ashwagandha Supplement

When it comes to experiencing the full health benefits of Ashwagandha, choosing the right supplement is important.

The KSM-66 ashwagandha root extract is a standardised organic supplement with 5% withanolide content, processed without the use of alcohol.

Additionally, paying attention to dosage is important. For instance, our Ashwagandha KSM66 capsules deliver 500mg of standardized root extract per serving. This is a great dose for supporting health and well-being, whereas other supplements may bot contain the same levels of active compounds.

Ashwagandha supplements are also available in various forms, including tablets, ashwagandha capsules, and liquid drops, catering to different preferences and needs such as ease of swallowing.

Precautions and Potential Side Effects

While Ashwagandha has numerous health benefits, it’s important to be aware of potential side effects and precautions. Consuming Ashwagandha might lead to stomach upset, diarrhea, and vomiting when taken in large doses.

Moreover, Ashwagandha has a risk of causing miscarriages and is likely unsafe for use during pregnancy.

Individuals with autoimmune diseases, such as multiple sclerosis, lupus, and rheumatoid arthritis, should use Ashwagandha with caution as it can stimulate the immune system and potentially worsen symptoms.

It’s always recommended to consult with a healthcare professional before starting any new supplement regimen. It is advisable for the following individuals to avoid using ashwagandha or its supplements due to potential health risks:

  • Pregnant women
  • Breastfeeding individuals
  • People with diabetes
  • People with high blood pressure problems
  • People with ulcers
  • People with autoimmune diseases

It is always recommended to consult with a healthcare professional before using any new food supplements.


In conclusion, Ashwagandha, the renowned herb from Ayurvedic medicine, offers a plethora of possible health benefits ranging from boosting cognitive function, enhancing physical performance, supporting immune system function, providing anti-inflammatory and pain-relief benefits, and exhibiting neuroprotective effects.

However, precautions and potential side effects should be taken into account, and consulting with a healthcare professional is always recommended before starting any new supplement regimen.
