Benefits of Ashwagandha (Withania somnifera)
Ashwagandha is a herb that is widely used for over 2500 years in Ayurveda – the Indian system of medicine. Ashwagandha is an Ayurvedic name for the herb Withania somnifera. It is also otherwise called “Indian ginseng,” owing to its ability to enhance stamina.
Plenty of wellness sources cite Ashwagandha’s remarkable therapeutic effects, including cardiovascular, neuroprotective, anti-anxiety, thyroid-stimulating effects. In the Ayurvedic system of medicine, Ashwagandha is primarily used to boost physical and mental health; prevent premature aging, and boost the body’s defense against diseases. These are just some of the health benefits of this powerful herb.
What is Ashwagandha?
Ashwagandha is a medicinal plant with varied uses for human health. “Ashwa” means horse “gandha” means smell. The word Ashwagandha literally translates to “smell of horse” since the roots smell like that of a horse. Since the herb is used primarily to strengthen the immune system, it is also known by other terms like “strength of a stallion.” Ashwagandha’s broad-spectrum benefits have been in use for centuries in India, where Ayurveda originated. Today, science shows that Ashwagandha’s beneficial effects are due to its anti-inflammatory and antioxidant properties.
Ashwagandha has multifarious rejuvenative effects on the human body; because of this, it is also referred to as a “royal herb.” It acts on various systems of the body, such as the nervous system, the immune system, the endocrines, the reproductive system, and the body’s energy production system.
How Ashwagandha benefits you?
Ashwagandha is primarily used as a rejuvenator to promote youthful physical and mental health, boost mood, as a tonic to middle-aged and elderly for longevity and well-being. It’s potent antioxidant properties support better defense against diseases, which may also help fight cancer. Ashwagandha’s ability to improve the body’s cell-mediated immunity makes it a safe rejuvenator and immune-booster. Cell-mediated immunity involves the activation of the body’s own defense cells and mechanisms that fight pathogens.
Ashwagandha is rich in steroidal lactones or withanolides which are unique to this herb. It includes withanolide A, withaferin A, and withanone. Studies show that these constituents in Withania somnifera contribute to its beneficial effects on health. The biologically active chemicals like alkaloids, withanolides, withaferins, saponins promote immunomodulatory actions. Compounds like withaferin-A, sitoindosides, and acylsterylglucosides in Ashwagandha work to fight stress.
Besides these unique compounds, Ashwagandha also includes aminoacids (includes tryptophan), sterols, tannins, neurotransmitters, triterpenes, and lignans. Other antioxidants include flavonoids, catalase, superoxide dismutase, and glutathione, which is considered the” mother of all antioxidants.”
A combination of unique compounds and other naturally occurring compounds attribute to Withania somnifera’s medicinal and beneficial effects on human health.
Health benefits of Ashwagandha
There are plenty of research reviews and abstract supporting the effects of Withania somnifera.
May have anti-cancer effects
Ashwagandha has anti-tumor effects, which is evident from the studies on cells and animals. The anti-tumor effects help in reducing the growth of tumor cells, which may also help in preventing the growth of cancerous cells. Researchers found that the root and leaf extracts of Withania somnifera showed anti-cancer properties. Not only did the withanolides in the herb fight the carcinogenic process, but they also demonstrated cancer-preventive effects. Researchers attribute the anti-cancer effects of Ashwagandha to its immuno-modulating effects, which play a crucial role in boosting the immune system of cancer patients. An animal study found that Ashwagandha supplementation was found to increase the white blood cell count, which helps protect the body from pathogens. Cancer patients show a reduced count of white blood cells after chemotherapy, supplementing with Ashwagandha may help boost their immune defenses against viruses and other pathogens.
Ashwagandha is used as a natural remedy for stress and anxiety treatment. It is an adaptogenic herb since it helps fight stress and improve one’s resilience to stress. Adaptogenic herbs act by normalizing the physiological process during stress and helps the body to cope with stress and adapt to changes. Ashwagandha also supports adrenal function and helps normalize the release of cortisol – the stress hormone. Adrenal glands release cortisol in response to stress. An overtaxed adrenal gland can lead to fatigue, emotional, and mental stress. When chronic stress impacts adrenal glands, it leads to a cascading effect. It disrupts hormone levels, including progesterone, which can affect fertility. Overworked adrenals also lower DHEA levels. DHEA is a hormone that is linked to longevity and maintaining a robust body.
One study found that Ashwagandha lowered cortisol production in chronically stressed adults. Also, a prospective, randomized, double-blind, placebo-controlled study confirmed that the extract of ashwagandha root reduces stress and anxiety in adults.
Boosts mood and lowers the risk of depression
Besides fighting stress, the bioactive constituents in Ashwagandha is also found to have anti-depressant effects. One study found that a specific constituent, namely glycowithanolides in Ashwagandha, demonstrated an anti-depressant effect. The researchers of the study supported the use of Ashwagandha as a mood stabilizer in clinical conditions of anxiety and depression. A recent 2019 study’s findings also suggested that extracts of Withania somnifera may hold promise in treating depression and anxiety symptoms in patients with schizophrenia.
Helps maintain stable blood sugar
Ashwagandha contains phenolic compounds, including flavonoids, which are known to possess blood sugar-lowering effects. Studies on both animals and humans confirm that Ashwagandha could act as an effective blood sugar stabilizer and has anti-diabetic properties. In a small clinical study, six subjects with mild diabetes (non-insulin dependent) and six subjects with mildly high cholesterol levels were administered Ashwagandha. They showed reduced blood sugar and cholesterol levels. A study on fructose-fed rats found that Ashwagandha inhibited the fructose-induced rise in blood glucose levels and prevented insulin-resistance and inflammation. The study was published in Reports of Biochemistry and Molecular Biology.
A 2015 study published in the journal, Phytochemistry, found that the leaf extracts of Ashwagandha improved insulin secretion and insulin sensitivity in muscle cells in lab studies. These findings indicate that Ashwagandha supplementation may help in improving insulin sensitivity and lowering inflammatory markers, which could help with reducing the risk of diabetes.
Improves stamina and endurance
Ashwagandha is also recommended for energy enhancement and enhancing exercise performance, possibly because of its ability to increase muscle mass and endurance. A randomized controlled study found that Withania somnifera increased muscle mass and strength in conjunction with resistance training. The clinical study was conducted on 57 young male subjects that were divided into two groups, one receiving the herb and another placebo. Compared to the placebo group, the treatment group showed increased muscle mass and also showed increased muscle size of the arms and chest. Also, researchers of the study observed that the treatment group showed reduced exercise-induced muscle damage, increased testosterone, and a higher decrease in body fat percentage compared to the placebo. Another study conducted on the safety and efficacy of the herb found that healthy men showed a significant gain in muscle strength after 30 days. The subjects received 750 to 1200 mg per day of Ashwagandha root in pulverized form.
As a herb rich in powerful antioxidants, Ashwagandha acts by lowering inflammation and suppresses pro-inflammatory cytokines. This property makes it a useful tool in treating many inflammatory conditions. Inflammation is a complex interplay between pro-inflammatory and anti-inflammatory cytokines. Higher activity of anti-inflammatory cytokines is beneficial in suppressing chronic inflammatory flare-up. Ashwagandha being an adaptogen, may favorably regulate the whole immune system by suppressing the overactive immune system, a reason for inflammation without any adverse effects. Laboratory studies confirm that Ashwagandha can act as a potential immuno-modulator and suppress inflammation.
Enhances under-active thyroids
Ashwagandha benefits people with under-active thyroids or Hashimoto’s disease. A study on Ashwagandha’s effects on patients with subclinical hypothyroidism found that the herb helps increase thyroid activity. The study found that 600 milligrams of Ashwagandha taken daily for a period of eight weeks showed improved serum Thyroid Stimulating Hormone (TSH) and thyroxine (T4) levels compared to placebo who received starch. In another study done to evaluate the effects of the herb on bipolar disorder showed an increase in T4 levels; however, the purpose of the study was different.
Promotes memory and brain health
Ashwagandha is often used for its neuroprotective and memory-enhancing abilities that stem from its antioxidant and anti-inflammatory effects. Stress in any form can cause damage to the brain and the nervous system. Studies show that Ashwagandha’s stress-fighting effects may also offer protective effects against neurodegenerative conditions like Alzheimer’s and Parkinson’s. Two main withanolides in Ashwagandha – withaferin A and withanolide D boost cognitive abilities. These two are naturally occurring steroids. A study found that when rats were injected with these compounds, they showed reduced plaque buildup, reversed behavioral deficits, and reduced amyloid-beta burden (causes Alzheimer’s) in their brains. A pilot study on humans found that Withaneria somnifera significantly enhanced the immediate and long-term memory in people with mild cognitive impairments. Researchers concluded that 300 milligrams per day for eight weeks boosted memory and cognitive skills in patients involved in the study.
Promotes the health of the heart
Ashwagandha is a powerful antioxidant and an anti-inflammatory agent. Studies show that Ashwagandha helps to lower high blood pressure, high cholesterol, and high triglyceride levels. In a study published in the International Journal of Ayurveda Research, Withania somnifera was found to physical performance, improve heart muscle function and endurance in healthy young adults.
Promotes fertility and sexual health
In Ayurveda, Ashwagandha is also used to boost low testosterone levels and improve male fertility. A 2010 study on Ashwagandha found that supplementation improved the testosterone levels in 75 men who were under infertility screening. Researchers also found that it reduced stress-induced oxidation levels in the seminal fluid of the infertile males in the treatment group. The study confirmed the positive outcome of ashwagandha treatment in infertile males. A 2015 pilot study found that ashwagandha extracts may help improve female sexual function and health.
Several factors determine the dosage of Ashwagandha. These include an individual’s age, the current state of health, medications in use, and several other conditions.
Most supplements recommend 1000-1500 milligrams per day. However, there isn’t an established dosage for Ashwagandha. A study published in the Journal of Ayurvedic and Integrative Medicine found that the herb is well-tolerated at gradually increasing doses ranging from 750 milligrams to 1250 milligrams per day. Researchers concluded that Ashwagandha was well-tolerated with safe organ function and blood test results.
While taking ashwagandha supplements, it is crucial to bear in mind that extracts are more potent than the crude powder from roots and leaves. Be sure to read the product labels and follow directions before using the supplement.
Some individuals may not like the strong smell of Ashwagandha; in such cases, capsules help. The powder form of Ashwagandha, when combined with other foods or drinks, acquires an improved appeal and pleasant smell.
Limitations of using Ashwagandha
Specific individuals and people with special health conditions should avoid Ashwagandha.
Pregnant women may develop miscarriages, and breastfeeding women should avoid it.
People with an autoimmune condition should not use it unless authorized by a physician.
Those with hyperactive thyroid condition such as Graves’ disease should avoid this herb, as it stimulates thyroid activity.
Type 1 diabetes patients should avoid it as it lowers blood sugar.
Patients taking medications for lowering blood sugar and blood pressure should avoid Ashwagandha or consult with their doctor before consuming it. Your doctor may adjust the medication dosage to suit the needs.
Patients taking immune-suppressing medications should avoid Ashwagandha, and must consult with their doctor first.
Patients undertaking surgery should stop Ashwagandha two weeks before surgery. Anesthesia and other medications, along with Ashwagandha, can slow down the central nervous system.
People with stomach ulcers should avoid this herb as it can irritate the gastrointestinal lining.
Of all the benefits of Ashwagandha, the herb’s ability to cope with stress is what makes it popular and widely used. Being an adaptogen, it helps to maintain the body’s homeostasis (balance), even in situations of physical or emotional stress.
Ashwagandha is rightly called the “strength of the stallion” for its incredible health benefits and ability to build endurance.
