Ashwagandha

Withania somnifera · the traceable root, weighed and named

All articles checked for accuracy against the GB NHC Register and all sources have citations with verified links to their relevant studies.

Ashwagandha (Withania somnifera) is a widely sold botanical in supplements. This piece explains what part of the plant matters, how extracts are defined, and what the regulatory picture looks like.

This article describes the plant and its key constituents, explains why root extracts and standardisation matter, summarises the shape of the clinical research, and outlines known safety considerations and how WellsparQ specifies the ingredient in its products.

What it is

A botanical extract from the root of Withania somnifera.

Where from

Withania somnifera (ashwagandha) — the dried root, commonly from India.

Known for

Contains steroidal lactones called withanolides and is sold as standardised root extract.

In WellsparQ

• CalmaRoot Blend400 mg (KSM-66 root, equivalent from extract)
• EveningCalm Blend250 mg (KSM-66 root extract, equivalent weight)

Ashwagandha has moved, in a few short years, from the shelves of the Ayurvedic dispensary to the front of the wellness aisle. That popularity brings a duty of care: to describe the plant accurately, to read a genuinely growing but still-imperfect evidence base honestly, and to be clear about safety. WellsparQ uses a branded, traceable root extract, and this piece explains why the root, the branding and the milligrams all matter.

The plant and the part that counts

Ashwagandha is Withania somnifera, a small woody shrub of the nightshade family (Solanaceae), native to the drier regions of India, the Middle East and parts of Africa. It is one of the most important herbs in Ayurveda, the traditional medicine of the Indian subcontinent, where it has been used for centuries — the name is often translated as "smell of the horse," a nod to the odour of the fresh root and to its reputation as a strengthening tonic ^¹.

The part traditionally valued, and the part used in the best-studied preparations, is the root. This distinction matters: root and leaf differ in their chemistry, and safety reviews suggest the root has the more favourable profile ^¹. WellsparQ's formulas specify root extract for exactly this reason.

Withanolides — the compounds it's grown for

Ashwagandha's characteristic constituents are the withanolides, a family of naturally occurring steroidal lactones (including withaferin A and the withanosides). Withanolides are the marker compounds by which a quality ashwagandha extract is standardised — a good extract states its withanolide percentage, so that each dose is repeatable rather than a variable scoop of powdered root ^¹.

This is where the branding becomes meaningful rather than merely decorative. KSM-66 is a widely used, standardised full-spectrum ashwagandha root extract with a defined withanolide content and a documented supply chain — which is precisely the kind of traceable, characterised material a careful formulator wants, in place of anonymous "ashwagandha powder" of unknown origin and strength.

Reading the research honestly

Ashwagandha is unusual among traditional botanicals in having a real cluster of modern randomised, placebo-controlled trials, most of them examining stress, anxiety and the stress hormone cortisol in adults under pressure.

• A randomised, double-blind, placebo-controlled trial of a standardised root extract reported reductions in self-rated stress and in morning cortisol versus placebo ^².
• A randomised controlled trial in chronically stressed adults similarly reported improvements in stress and anxiety measures ^³.
• Systematic reviews gathering these trials generally find a consistent direction of effect on stress-related outcomes ^⁴.

That is a more substantial evidence base than most herbs can claim. But honesty requires the caveats, and they are real: the trials are mostly small and short, many are funded by extract manufacturers, they use different extracts, doses and rating scales, and long-term data are scarce ^⁴. A promising, coherent signal is not the same as settled proof, and — as below makes plain — none of this may be presented as a WellsparQ benefit in any case, because ashwagandha has no authorised health claim.

Safety: a section that has grown more important

Ashwagandha has a long traditional record of use, but recent pharmacovigilance has raised a specific concern that a responsible brand must flag.

• The US National Institutes of Health liver-injury resource, LiverTox, now records ashwagandha as a "probable" cause of clinically apparent liver injury, describing a pattern of cholestatic hepatitis typically appearing within one to three months of use, with published case reports (one of which required a liver transplant) ^⁵. Such cases appear to be rare and usually reversible on stopping, but they are documented.
• Ashwagandha is not suitable during pregnancy (it has a traditional reputation as an abortifacient) or breastfeeding ^¹⁵.
• It may interact with thyroid, sedative, immunosuppressant and diabetes medicines, and — as a nightshade — is best avoided by anyone with a known sensitivity ^¹.

None of this makes ashwagandha a dangerous ingredient for most healthy adults, but it does mean it deserves respect, clear directions, and a genuine "speak to your GP or pharmacist first" for anyone with a liver condition, on medication, or pregnant or breastfeeding.

How WellsparQ uses it

WellsparQ uses a branded, standardised root extract, declared to the milligram.

Source: WellsparQ Supplements Database. Both use a named, traceable root extract at a stated dose rather than a vague herb weight — the transparency the brand holds as standard. The formulas are plant-based and suitable for vegetarians and vegans.

Sensible use

Take as directed. Do not use in pregnancy or breastfeeding. Anyone with a liver condition, thyroid disorder, or on regular medication should speak to a GP or pharmacist before use, and anyone who develops symptoms such as unusual tiredness, loss of appetite, dark urine or yellowing of the skin or eyes should stop and seek medical advice ^⁵.
