Ashwagandha Benefits: What This Adaptogen Can Do For Stress, Sleep and Energy
Share
Written By: Sarah
Ashwagandha (Withania somnifera) is one of the most important herbs in Ayurvedic
medicine, where it has been used for over 3,000 years as a rejuvenating tonic. Known in India as "Indian Ginseng" for its restorative properties, ashwagandha has become one of the most popular adaptogenic herbs in Australia and around the world.
At Nimbin Apothecary, our qualified naturopaths and herbalists have been helping Australians find natural support for stress, sleep and energy for over 35 years. Ashwagandha is one of the herbs we reach for most often in our dispensary, and this guide draws on that hands-on experience alongside the available research to give you a practical, evidence-informed overview.
What Is Ashwagandha?
Ashwagandha is a small evergreen shrub that grows in India, the Middle East and parts of Africa. The root is the most commonly used part of the plant in herbal medicine. Its botanical name, Withania somnifera, gives a clue to one of its primary uses: "somnifera" translates to "sleep-inducing" in Latin.
Ashwagandha belongs to a class of herbs known as adaptogens. Adaptogens help your body adapt to physical, mental and emotional stress by supporting the regulation of your stress response system, particularly the hypothalamic-pituitary-adrenal (HPA) axis. Rather than sedating you or stimulating you, adaptogens work to bring your body back toward balance.
At Nimbin Apothecary, we stock ashwagandha as a pure root powder that can be mixed into warm milk, smoothies or food. It sits in our Sleep and Nervous System Support collection alongside other calming herbs like passionflower, chamomile, lavender and lemon balm.
Benefits of Ashwagandha
Ashwagandha is one of the most extensively studied adaptogenic herbs, with a growing body of clinical research supporting its traditional uses. Here is what the current evidence suggests.
Stress and Cortisol Reduction
This is where ashwagandha has the strongest research behind it. Multiple clinical trials have shown that ashwagandha root extract can significantly reduce cortisol levels and perceived stress in adults.
A 2012 study published in the Indian Journal of Psychological Medicine found that participants who took ashwagandha root extract for 60 days had significantly lower cortisol levels and reported substantially reduced stress compared to the placebo group. A 2019 systematic review and meta-analysis confirmed these findings across multiple trials.
In our dispensary, ashwagandha is one of the first herbs our naturopaths consider for customers dealing with chronic stress, burnout and adrenal fatigue. It pairs well with our Adrenal Restorative, which is formulated specifically for rebuilding depleted stress reserves.
Sleep Quality
The "somnifera" in ashwagandha's botanical name is well deserved. Research suggests that ashwagandha can improve both sleep quality and sleep onset, particularly in people whose sleep is disrupted by stress and anxiety.
A 2019 study in the journal Cureus found that participants taking ashwagandha root extract experienced significant improvements in sleep quality compared to the placebo group. The researchers noted improvements in sleep onset latency (how long it takes to fall asleep), sleep efficiency and total sleep time.
Unlike pharmaceutical sleep aids, ashwagandha is not a sedative. It works by addressing the underlying stress and nervous system activation that keeps people awake, which is why it tends to improve sleep without causing morning drowsiness.

collection, which includes calming teas like Chill Out Tea and Rest and Relax, along with passionflower, lavender and relaxing massage oil.
Energy and Vitality
This might seem contradictory for a herb that also helps with sleep, but it is exactly how adaptogens work. Ashwagandha does not sedate you during the day or stimulate you at night. It helps regulate your stress response so your body can produce energy when you need it and wind down when it is time to rest.
Several studies have found that ashwagandha can improve physical stamina and reduce fatigue. A 2015 study in the Journal of the International Society of Sports Nutrition found that ashwagandha supplementation was associated with significant increases in muscle strength and recovery.
For those dealing with deeper fatigue, our Energy and Vitality collection combines ashwagandha with medicinal mushrooms like lion's mane, cordyceps and mushroom elixir, plus whole food supplements like our Vitality Pills (chicken liver capsules) for bioavailable iron and B12.
Immune Function
Ashwagandha has demonstrated immunomodulatory effects in research, meaning it can help regulate immune function rather than simply boosting it. The withanolides (active compounds in ashwagandha) have been shown to support the activity of natural killer cells and other immune markers.
For targeted immune support, our Immune Support collection features herbal extracts, medicinal mushrooms and vitamin C alongside adaptogenic herbs.
Inflammation
The withanolides in ashwagandha have demonstrated anti-inflammatory properties in both laboratory and clinical studies. While ashwagandha is not a topical anti-inflammatory, its systemic effects may help manage low-grade chronic inflammation that contributes to fatigue, joint stiffness and general unwellness.
How to Take Ashwagandha Powder
The traditional Ayurvedic method is to mix half to one teaspoon of ashwagandha powder with a cup of warm milk (dairy or plant-based), a little honey and a pinch of cinnamon. This combination is sometimes called "moon milk" and is often taken in the evening to support wind-down and sleep.
You can also add ashwagandha powder to smoothies, porridge, hot chocolate or golden milk. The taste is earthy and slightly bitter, so combining it with warmer spices like cinnamon, cardamom or vanilla helps soften the flavour.
Some people prefer to take ashwagandha in the morning for stress resilience throughout the day, while others take it in the evening for sleep support. Both approaches are valid. If you are unsure, our herbalists can advise based on your specific situation.
Dosage
Based on the available research and our dispensary experience, a reasonable daily
dose for most adults is between 1 and 3 grams of ashwagandha root powder per day. That is roughly half a teaspoon to one and a half teaspoons.
Clinical trials have typically used doses ranging from 300mg to 600mg of concentrated root extract, which is equivalent to approximately 1.5 to 6 grams of whole root powder depending on the extraction ratio. Our ashwagandha powder is a whole root powder (not a concentrated extract), so the standard recommendation of half to one teaspoon (approximately 2 to 3 grams) daily is a good starting point.
Start with a smaller amount and increase gradually over one to two weeks. Most people notice the effects of ashwagandha after two to four weeks of consistent daily use. Like most adaptogens, ashwagandha works cumulatively rather than providing an immediate effect.
What to Look for When Buying Ashwagandha
Check whether the product is made from root only. The leaves contain different compounds and are not traditionally used in Ayurvedic medicine. Quality ashwagandha powder should be made from the dried root.
Look for a product with a clear, single ingredient list. Ashwagandha powder should contain only Withania somnifera root powder, with no fillers, binders or flow agents.
Consider the source. As with all herbal products, quality varies significantly between suppliers. At Nimbin Apothecary, our naturopaths select products that meet the standards we apply across our entire herbal dispensary, where we have been formulating and dispensing herbal medicines since 1990.
Side Effects and Safety
Ashwagandha is generally well tolerated. The most commonly reported side effects in clinical trials are mild and include drowsiness, stomach upset and diarrhoea, usually at higher doses.
However, ashwagandha is not suitable for everyone. Do not take ashwagandha if you are pregnant or breastfeeding. Use caution if you have a thyroid condition, as ashwagandha may affect thyroid hormone levels. Consult your healthcare practitioner if you are taking medications for blood pressure, blood sugar, thyroid or immune suppression, as ashwagandha may interact with these.
In recent years, rare cases of liver injury associated with ashwagandha use have been reported in medical literature. While these cases are uncommon and causality is not fully established, it is worth noting. We always recommend consulting with a qualified health professional before starting any new supplement.
Frequently Asked Questions
How long does ashwagandha take to work? Most people notice improvements in stress levels and sleep quality within two to four weeks of consistent daily use. Some people report feeling calmer within the first week, while the energy and vitality benefits typically take four to eight weeks to fully develop.
Can I take ashwagandha every day? Yes. Ashwagandha is traditionally used as a daily tonic and the clinical trials that demonstrated its benefits used daily dosing over periods of 8 to 12 weeks. Some practitioners recommend cycling ashwagandha (for example, taking it for 8 weeks then having a 2 week break), but this is a matter of practitioner preference rather than a safety requirement.
Should I take ashwagandha in the morning or at night? Either works. If your primary goal is stress resilience during the day, morning is ideal. If you are using it for sleep support, take it in the evening with warm milk. Some people split their dose, taking half in the morning and half in the evening. Our herbalists can help you work out the best approach for your needs.
Can I take ashwagandha with other herbs? Absolutely. Ashwagandha combines well with other adaptogenic and calming herbs. In our dispensary, we often recommend it alongside chamomile or passionflower for sleep, lion's mane for cognitive support, or medicinal mushrooms for broader vitality. Our Mushroom Elixir pairs particularly well with ashwagandha for combined energy and resilience support.
Is ashwagandha safe for children? We recommend consulting a qualified healthcare practitioner before giving ashwagandha to children. Most clinical research has been conducted in adults.
