What Is Ashwagandha? The 'Horse-Smell' Root Behind a Modern Favourite
Most plants are named for how they look. Ashwagandha is named for how it smells. In Sanskrit, ashva means horse and gandha means smell, and anyone who has opened a bag of the fresh root will tell you the name is honest. It has a strong, earthy, unmistakably stable-yard aroma.
In Ayurveda, India's traditional system of medicine, the name has long been read a second way, too: as a hint that the root offers something of a horse's strength and vigour.
Then there's the botanical name, Withania somnifera. Somnifera is Latin for "sleep-inducing". The Germans call the plant Schlafbeere, the "sleep berry". So one plant carries names that suggest both the energy of a horse and the pull of sleep. That apparent contradiction is a good way into understanding why ashwagandha has become one of the most talked-about herbs in the world.
The plant itself is surprisingly modest: a small, scruffy shrub from the nightshade family, which makes it a distant cousin of tomatoes and tomatillos. It produces bright orange-red berries wrapped in papery, lantern-like husks. Pretty as they are, the berries aren't what people are after. The part that matters grows underground: the pale, fibrous root.
What is ashwagandha used for?
A Rasayana in Ayurveda
Ashwagandha has been part of Ayurvedic practice for thousands of years and appears in the writings of Charaka, one of Ayurveda's founding physicians. It belongs to a special category of herbs called Rasayana: rejuvenating herbs traditionally associated with longevity, vitality and resilience. Rasayana herbs aren't reached for when something goes wrong. They're meant to be taken steadily, as part of looking after yourself over the long run.
That same role explains its nickname, "Indian ginseng". The two plants aren't related, but they hold a similar place in their own traditions as restoring, strengthening herbs.
The original adaptogen
Today, ashwagandha is usually described as an adaptogen. The word is used for herbs traditionally associated with helping the body cope with everyday stress, rather than pushing it in one direction like a stimulant or a sedative. It's a descriptive term, not a medical category, but it captures the plant's reputation well. Ashwagandha isn't known for jolting you awake or knocking you out. It's known for feeling steadying.
That helps resolve the horse-versus-sleep puzzle. In Ayurveda it has been taken to support strength and stamina, and it's also traditionally taken in the evening, often stirred into warm milk.
What's inside the root
The compounds researchers find most interesting in ashwagandha are called withanolides, named after the plant itself. They're a family of naturally occurring steroidal lactones that are fairly distinctive to ashwagandha and its close relatives, and they're the reason supplement makers often talk about how much "withanolide content" an extract contains.
What the research says
Ashwagandha has more human research behind it than most traditional herbs. One of the most cited studies is a 2012 randomised, placebo-controlled trial in India involving 64 adults with a history of chronic stress. Over two months, the group taking a standardised ashwagandha root extract scored lower on stress questionnaires and had lower levels of cortisol, the hormone most associated with stress, than the placebo group.
It's an interesting result, but it's one study using one specific extract, and it doesn't mean every ashwagandha product will have the same effect. The broader body of research is growing but varies in size and quality. What it does show is why scientists, and not just herbalists, have taken an interest in this root.
Why we chose ashwagandha for QiMycology
QiMycology is rooted in Traditional Chinese Medicine, so ashwagandha might look like an unexpected choice. It's the only ingredient in either of our blends that comes from outside the Chinese tradition, and that was deliberate.
It fills a specific gap in an evening blend. Qi Harmony is built for the end of the day. Suan Zao Ren, the sour jujube seed, is TCM's classic evening herb, associated with settling the mind at night. Reishi is TCM's great long-term tonic, taken steadily over time. Alongside them we wanted one ingredient from Ayurveda, India's traditional medicine, where ashwagandha has long been taken in the evening, often with warm milk.
Two traditions, one way of thinking. Ayurveda's Rasayana herbs and TCM's tonic herbs share a philosophy: take them consistently, as part of a routine, rather than as a quick fix. Ashwagandha and Reishi are both prized for exactly that kind of steady, long-term use, which is why they sit comfortably together.
A supporting role, not the headline. In Harmony, ashwagandha provides 600 mg per serving, alongside 1,200 mg each of Reishi and Suan Zao Ren. It's there to round out the blend, not to dominate it.
That's the thinking behind a blend rather than a single-ingredient pouch. Each ingredient brings something different, and the combination reflects how both Ayurveda and TCM have always worked: herbs chosen to complement one another.
Frequently asked questions
What does "ashwagandha" mean? It's Sanskrit for "horse smell", from the strong scent of the fresh root. Its botanical name, Withania somnifera, means "sleep-inducing".
Is ashwagandha the same as ginseng? No. It's sometimes called "Indian ginseng" because it plays a similar restorative role in Ayurveda, but it belongs to the nightshade family and isn't related to true ginseng.
Which part of the plant is used? The root. Supplements usually contain dried root powder or a root extract. The berries aren't used.
Why is an adaptogen in an evening blend? Adaptogens aren't stimulants. Ashwagandha has long been taken in the evening in Ayurveda, and its Latin name hints at that side of its reputation. In Qi Harmony, it sits alongside two of TCM's classic evening herbs.
Is ashwagandha safe? I've seen it in the news. In the UK, the Food Standards Agency has asked its independent Committee on Toxicity to review the evidence. While that review continues, the FSA advises pregnant women and people with existing liver conditions to avoid ashwagandha supplements. We also don't recommend Qi Harmony if you're breastfeeding or under 18. If you have a thyroid or autoimmune condition, or take any regular medication, speak to your GP or pharmacist first. We follow UK guidance closely and will update this page if it changes.
Do I need to take it with food? Follow the directions on your product's label. In Ayurveda, it has traditionally been taken with warm milk in the evening.
A root worth getting to know
Ashwagandha is a plant of nicknames: horse smell, sleep berry, Indian ginseng. Each one captures part of the story: a humble, earthy root that Ayurveda has prized for thousands of years as a steady, restoring presence, and that modern researchers have spent the past few decades studying closely.
In Qi Harmony, our evening blend, it plays a supporting role. Each serving contains 600 mg of Ashwagandha alongside 1,200 mg of Reishi and 1,200 mg of Suan Zao Ren, bringing together the best of Ayurveda and Traditional Chinese Medicine in one calm, considered evening ritual.
