Ashwagandha: What Is It? Traditional Uses, Forms and Safety Guide

Updated: 24 October 2026

Ashwagandha is one of the best-known plants associated with traditional Ayurveda. Its botanical name is Withania somnifera, and it is sometimes called Indian ginseng or winter cherry.

Ashwagandha has a long history in Indian herbal traditions and is found in a variety of commercially available preparations.

But what is ashwagandha, how is it traditionally used, and what should customers in the UK know before considering a product?

This guide explores the plant’s history, botanical characteristics, product forms and important safety considerations.

What Is Ashwagandha?

Ashwagandha (Withania somnifera) is a small shrub belonging to the Solanaceae family, which also includes tomatoes and potatoes.

The plant grows in parts of Asia, Africa and southern Europe.

It has oval leaves, small flowers and orange-red berries enclosed by a papery covering.

The roots are particularly associated with traditional Ayurvedic preparations, although commercial formulations can use different plant materials.

Ashwagandha is not botanically related to the true ginseng plant, despite occasionally being called Indian ginseng.

Ashwagandha in Traditional Ayurveda

Ashwagandha has featured in Indian Ayurvedic traditions for centuries.

Traditional Ayurvedic literature describes the plant within a broader system of botanical preparations, dietary practices and lifestyle guidance.

It is often discussed in connection with the Ayurvedic concept of rasayana, traditionally associated with restorative practices.

These descriptions are part of its cultural and historical background. They should not be interpreted as proof that a particular ashwagandha supplement improves health or treats a medical condition.

Common Forms of Ashwagandha

Ashwagandha is available in several commercial forms.

Ashwagandha Root Powder

Root powder is produced from processed and ground plant material.

Products may differ in their composition, processing methods and recommended serving instructions.

Ashwagandha Capsules

Capsules may contain powdered root, an extract or a mixture of botanical ingredients.

The amount of ashwagandha per capsule varies between products.

Ashwagandha Tablets

Tablets are another common packaged form.

Some contain ashwagandha as a single ingredient, while others combine it with additional botanical materials.

Ashwagandha Extracts

Extracts differ from ordinary root powders because their manufacturing processes may concentrate certain plant constituents.

Two extracts with the same weight are not necessarily equivalent.

Customers should check the ingredient list and product specifications rather than assume all preparations are interchangeable.

What Are Withanolides?

Withanolides are a group of naturally occurring compounds found in plants such as Withania somnifera.

They are frequently discussed in research examining the chemical composition of ashwagandha.

Some manufacturers standardise their extracts according to particular withanolide concentrations.

However, a stated withanolide percentage does not by itself establish that a product is safe, effective or authorised to make medical claims.

The overall composition and manufacturing quality of a preparation also matter.

What Does Scientific Research Say?

Ashwagandha has been investigated in laboratory, animal and human studies.

Research has examined different preparations, doses and biological effects.

However, research on one particular extract cannot automatically be applied to all commercially available ashwagandha products.

Study findings should also be distinguished from health claims that are legally permitted in UK food advertising.

Ashwagandha supplements should not be presented as established treatments for anxiety, depression, cancer, thyroid disease, diabetes or other medical conditions.

Important Safety Information

Ashwagandha is not suitable for everyone, and natural origin does not guarantee safety.

The UK Food Standards Agency has highlighted potential safety concerns relating to ashwagandha supplements, including reports involving liver problems, thyroid effects and changes in blood sugar.

Before considering an ashwagandha product, seek advice from a GP or pharmacist, particularly if you:

Take prescribed medication.
Have a thyroid condition.
Have liver or kidney problems.
Have diabetes or another ongoing medical condition.
Are pregnant, breastfeeding or trying to become pregnant.
Have previously experienced adverse reactions to herbal products.

Herbal preparations may interact with medicines or be unsuitable in particular circumstances.

Children should not use herbal medicines without appropriate medical advice.

If you develop symptoms that could indicate an adverse reaction after using an herbal product, stop using it and seek medical advice.

Do not stop prescribed medication or substitute a supplement for medical treatment.

How to Compare Ashwagandha Products

When reviewing different products, consider:

1. Botanical identification

Check whether the ingredient is identified as Withania somnifera.

2. Plant part used

A preparation may contain root material, an extract or other specified plant parts.

3. Ingredient list

Read the complete ingredients, including any additional botanicals, fillers and allergens.

4. Quantity and composition

Compare the amount supplied and any clearly explained extract specifications.

5. Manufacturer information

Look for a clearly identified manufacturer or responsible business.

6. Safety and regulatory information

Review relevant warnings, directions and the product’s UK regulatory status.

Products intended for medicinal use may require appropriate medicines authorisation or registration. Food supplements must comply with applicable food-safety, labelling and advertising requirements.
