Ashwagandha's Health Benefits According to Science

Ashwagandha (withania somnifera) is popularly known as the king of Ayurvedic herbs. Ayurveda is a form of alternative medicine based on Indian principles of natural healing. It is an incredibly healthy botanical, often referred to as Indian Ginseng. It is a small plant with yellow flowers that is native to India and North Africa.

It is classified as an adaptogenic herb, and while all adaptogens reduce stress (cortisol), ashwagandha’s ability to do so is superior to the rest.

Ashwagandha has many benefits for the brain, where it can increase energy, sharpen focus, and reduce symptoms of anxiety and depression. It has been used this way for over 3,000 years.

Its name literally means “smell of a horse” since it was said to bestow the strength and stamina of a horse on anyone who used it. An Ayurvedic scholar from 100BC, Charaka, said of Ashwagandha, “One obtains longevity, regains youth, gets a sharp memory and intellect and freedom from diseases, gets a lustrous complexion, and strength of a horse.”

The most well-known active ingredients in Ashwagandha are withanolides. Alongside these valuable compounds are many other beneficial elements, including flavonoids and antioxidants such as catalase, superoxide dismutase and glutathione, which is known as the “mother of all antioxidants.” It also contains alkaloids, amino acids (including tryptophan), neurotransmitters, sterols, tannins, lignans and triterpenes. It is these valuable compounds together that allow for ashwagandha’s hugely beneficial pharmacological activities.

Due to the combined benefits of the herb’s valuable compounds, we used a 60:1 full-spectrum concentrated extract, which is made up of at least 5% withanolides. This means that each 100mg serve in a Savvy product is equivalent to 6grams of this superherb!

The reason we love it in our Savvy products is because Ashwagandha has been proven to:

Reduce stress, anxiety, and mental fatigue; and

Increase mood, enhance brain function and improve memory; and

Boost performance + energy while being a potent anti-inflammatory and antioxidant; and

Support healthy brains and hearts.

We will now delve into the scientific evidence behind the benefits of this amazing herb. For each scientific resource, at Savvy, we have referenced the study, linked to it and also provided an interesting quote from the study. Occasionally, we will also provide further commentary on the study.

Please note that we have referenced the scientific literature that support the benefits of ashwagandha, and to make it easier to read, we have 'indented' every second resource.

Each reference will have a quoted excerpt from the scientific literature, and occasional observations made about the evidence as well.

We really hope you enjoy a look into the many years of research we have compiled when formulating Savvy...

Benefit 1 - Ashwagandha can reduce stress, anxiety, and mental fatigue

Ashwagandha’s chief benefit is that it actually annihilates stress in the body. Ashwagandha improves our resistance to stress and studies show that it thereby improves people’s self-assessed quality of life. Ashwagandha is extremely dynamic in how it combats stress and fatigue!

The study, below, found ashwagandha lowered stress and anxiety by over 60% from consistent use. The reference to the study is:

Chandrasekhar, K. et al. ‘A prospective, randomized double-blind, placebo-controlled study of safety and efficacy of a high-concentration full-spectrum extract of ashwagandha root in reducing stress and anxiety in adults.’ in Indian Journal of psychological medicine. Volume 34, issue 3, July 2012, pp 255-262. [https://www.ncbi.nlm.nih.gov/pubmed/23439798]

After the findings in this study, the authors concluded:

“The findings of this study suggest that a high-concentration full-spectrum Ashwagandha root extract safely and effectively improves an individual's resistance towards stress and thereby improves self-assessed quality of life.”

The above study found that Ashwagandha helps with multiple levels of stress, these being cortisol levels, anxiety and insomnia. In the study, 64 healthy participants were enrolled, between the ages of 18 and 54. Half were given Ashwagandha daily for 60 days, and the other half got a placebo.

The Ashwagandha group saw improvements to their stress baseline by 69.7%, 64.2%, and 75.6%. These improvements were across all three measures including cortisol, anxiety, and insomnia.

The below graph from this trial clearly shows the power of this herb as it influences the body over 60 days from baseline!

PSS is the Perceived Stress Score (which dropped by 44% over 60 days)

GHQ-28 measures levels of anxiety, nervousness, social dysfunction, depression. (Levels of which dropped by 72.3% over 60 days)

DASS (Depression Anxiety Stress Scale) (Levels of which dropped by 71.6% over 60 days)

Serum Cortisol levels - (useful to assess the effect of the treatment on cortisol (the stress hormone in your body) level) (Which dropped by 27.9% over 60 days)

Further scientific evidence that support the benefits of Ashwagandha:

In the above study, when anxiety levels were measured after the 12-week period, the group who received ashwagandha had anxiety scores that decreased by 55 percent and the psychotherapy group’s scores decreased by 30.5 percent. Showing that Ashwagandha can even outperform psychotherapy.

“Seventy-five participants (93%) were followed for 8 or more weeks on the trial. Final BAI scores decreased by 56.5% (p<0.0001) in the NC group… Significant differences between groups were also observed in mental health, concentration, fatigue, social functioning, vitality, and overall quality of life with the NC group exhibiting greater clinical benefit. No serious adverse reactions were observed in either group.”

Benefit 2 - Ashwagandha can increase mood, sharpen focus and enhance memory

Ashwagandha supplements may improve mood, brain function, memory, reaction times and the ability to perform tasks.

“After eight weeks of study, the ashwagandha treatment group demonstrated significant improvements compared with the placebo group in both immediate and general memory. The treatment group also demonstrated significantly greater improvement in executive function, sustained attention, and information-processing speed.

Ashwagandha may be effective in enhancing both immediate and general memory in people with MCI as well as improving executive function, attention, and information processing speed.”

Benefit 3 - Ashwagandha can boost performance + energy while being a potent anti-inflammatory and antioxidant

Because ashwagandha works as an adaptogen that can reduce the body’s stress hormones, it can help to boost your immune system and reduce inflammation within the body. Due to its positive, calming-yet-energising effects on the brain, and its ability to lower stress hormones, ashwagandha showed improvements in concentration, motivation and stamina in conducted studies.

[drdezwholisticascensionist]

Entrepreneurial Wisdom

Entrepreneurial wisdom was a core global leadership practice, and a Big 5 Personality Type titled: Conscientiousness (Tubbs & Schulz, 2006). What I found was that “conscientiousness [was] related to almost all job-related criteria (e.g., performance, training, attendance) across almost all jobs” (Heggstad, 2017, p. 4) and that universally, conscientiousness is viewed as the most important of the Big Five. 

Now, I have a better understanding of the “relationship between conscientiousness and job performance [particularly as it pertains to being] stronger in autonomous situations” (p. 4), such as when working as a Instacart shopper or a Wholistic Ascensionist Consultant, or even a blogger. However, this does not include the operations end of the organization.

For example, with Instacart, when a batch is received and it’s time to start shopping that app suggests the best or quickest route to locate the items. However, when an Instacart shopper enters into a store that has implement ‘walking directions,’ due to social distancing -- it may not be the best suggested route -- leaving the shopper exceeding the completion timeline. Additionally, as an autonomous and conscientious Instacart shopper, I am not in control of the of the delivery schedule. For instance, having a shopping batch with 25 items consisting of three 12 packs of pop, a 17 lbs bag of dog food, another six pack, as well as the remaining bags of groceries and a delivery time of 11:11 am. Although the location was less than five miles aways from the store, that did not leave enough room for travelling to the location, unloading, taking a photo of the items, and executing the time of delivery. With COVID-19 all customers are asking for the deliveries to be left at the door, which equates taking a picture of the delivered items and entering the photograph into the system.

To cut down on some of that time, and to give the customer notification that their delivery has arrived, I take a picture of the first unload and send the image, and then capture another photo once the delivery is completely offloaded for documentation. That way the customer has been notified and I can continue to move forward.

All of these things eat up time. Not to mention GPS systems and newly constructed housing communities that aren’t on certain systems, but are available on other GPS systems, and waiting in route to download the apps. That all takes time, while the clock is ticking. We cannot forget customers and the time. When customers are not prepared with their photo IDs for alcohol purchases -- again time is waisted, and the shopper (outside of COVID-19) would be penalized. So although an Instacart shopper may have high conscientiousness and use their autonomy to the best of their ability there are other factors that remain, and present challenges in virtual team settings. However, this doesn’t have to remain discouraging, especially with applying one’s own entrepreneurial Spirit.

I found wisdom in the use of the “entrepreneurial spirit,” which reinforced my global virtual membership and self-concept. It was through personal drive and a keen development of self-awareness that reinforced the following: personal knowledge updates and upgrades, while self-concept aided my desires to experience new opportunities. Although, personal drive had bouts of creative dissatisfaction, those instances didn’t last long with the enhancement of reflective learning through self-awareness. Along with personally selected individual interventions (Blustein, 2013), a truth factor came to light, which included the acknowledgement that the most creative dissatisfaction came from restricted external sources and/or persons or groups unfamiliar with the process and practice. 

Overall, when engaged in personal transformation as a global virtual team member dependability and responsibilities increased, as well as persistence in achievement-oriented activities, which demonstrated a higher degree of openness to global virtual experiences. Although conscientiousness was highly rated, extraversion along with proactive and action-oriented personality traits were also necessary to build the essentials of virtual closeness, including trust, increased performance and success (Jokinen, 2005). For instance, contacting Instacart Care during some of these challenging occurrences relieved some of the tensions and stressors that were out of my control as an Instacart shopper. Being able to chat with shopper care representatives allowed shoppers to correct information and documentation, and settle matters with customers. In these moments Instacart Care were a blessing, especially so since they to were experiencing high call volume in a system that was already overloaded and backed up with orders. In addition, the use of proactive concentration early on aided in a willingness to self-expression, with a spiritual connection, which maintained an openness among other virtual global members that entailed the ability to build on innate talents and gifts. However, to do this successfully required a combination of both management and leadership skills to get to the end goal – successful delivery completion – with excellent performance, process, and procedure.
