Ashwagandha is one of the most widely used herbs in the world, and one of the most inconsistently made. The same name covers products that differ enormously in what part of the plant they use, how they are prepared, and what is actually in the jar. This guide covers what ashwagandha is, its place in Ayurvedic tradition, the differences that matter when choosing one, and how to bring it into a daily practice.
What is ashwagandha?
Ashwagandha is the common name for Withania somnifera, a small woody shrub in the nightshade family, native to India, the Middle East, and parts of Africa. Its root has been used in Ayurvedic practice for thousands of years, where it is one of the most frequently referenced herbs in the classical texts.
The Sanskrit name translates roughly as “the smell of a horse” — a reference both to the distinctive aroma of the fresh root and, traditionally, to the strength and steadiness the herb was associated with. It is sometimes called “Indian ginseng,” though it is not botanically related to ginseng at all.
In Ayurveda ashwagandha is classified as a rasayana — a rejuvenating tonic, taken consistently over long periods rather than occasionally. It is also one of the herbs most often described in modern usage as an adaptogen: a category of plants traditionally used to help the body meet everyday demands and maintain its own balance.
Sun Potion’s Ashwagandha is a cold-water extract of the root.
Root versus leaf — and why it matters
This is the single biggest difference between ashwagandha products, and most labels don’t make it obvious.
Traditional Ayurvedic use centres on the root. The classical preparations, and the overwhelming majority of the traditional record, describe root preparations. The leaf has its own separate traditional applications, but it is not interchangeable with the root, and the two have different compositions.
Leaf material is cheaper and more abundant than root. Some products use it, or blend it in, without saying so. If a label says only “ashwagandha” or “ashwagandha extract” with no plant part named, that is worth asking about. “Root extract” stated plainly is the baseline to look for.
How it’s prepared
Preparation method changes the finished powder as much as the plant part does.
- Simple milled root powder — the dried root, ground. The most minimally processed form, and the closest to the traditional preparation.
- Water extraction — the root is extracted in water and the extract dried. Water is the traditional solvent and the gentlest option.
- Solvent extraction — some commercial extracts use alcohol or other solvents to concentrate specific constituents more aggressively.
None is automatically superior, but they are genuinely different products, and a brand that states its method is telling you something a brand that stays silent is not.
What separates a quality ashwagandha
Five things to check.
1. The plant part, stated plainly
Root, leaf, or a blend — it should say so.
2. The preparation method
Milled, water-extracted, or solvent-extracted. Named, not implied.
3. Extract ratio, if it’s an extract
A ratio such as 10:1 describes how much raw material went into the finished powder. It is a specification, not a quality guarantee — but its absence on an extract is a gap.
4. Withanolide content, if disclosed
Withanolides are the marker compounds used to characterise ashwagandha in the lab, and some brands publish a percentage. Treat this as a specification for comparing like with like, not as a claim about what the herb does. Many quality products don’t state it; the useful signal is whether a brand can answer when asked.
5. Independent purity testing
Ashwagandha is a root crop, and roots take up what is in their soil. Third-party testing for heavy metals and microbials is a baseline worth expecting of any root powder.

Ashwagandha in a daily practice
Ashwagandha is traditionally enjoyed in small, regular amounts over long periods — the rasayana approach — rather than in large occasional doses. About half a teaspoon is a common serving.
Its flavour is earthy, bitter, and distinctly herbal, which is why it is traditionally taken with something rich rather than in plain water. Warm milk or plant milk with honey is the classical pairing and still the most forgiving. It also blends into cacao, chai, coffee, and smoothies, and sits comfortably alongside other tonic herbs — tocos for texture, or cacao for depth.
For travel or a smaller commitment, the Travel Ally size is the same powder in a smaller jar.
If you are pregnant, nursing, taking medication, or managing a health condition, consult your healthcare practitioner before adding ashwagandha or any new herb to your routine. Ashwagandha is in the nightshade family, which is worth knowing if you avoid nightshades.
Frequently asked questions
What is ashwagandha?
Ashwagandha is the common name for Withania somnifera, a shrub whose root has been used in Ayurvedic practice for thousands of years. It is classified in Ayurveda as a rasayana, or rejuvenating tonic, and is widely described as an adaptogen.
What is ashwagandha traditionally used for?
In Ayurvedic tradition it has been used as a daily tonic herb, traditionally associated with steadiness, everyday resilience, and overall balance and well-being, taken consistently over time rather than occasionally.
Is ashwagandha root or leaf better?
Traditional Ayurvedic use centres on the root, and most classical preparations are root preparations. Leaf has separate traditional applications and is not interchangeable. Look for the plant part named on the label.
How do I take ashwagandha powder?
About half a teaspoon, stirred into warm milk or plant milk, cacao, chai, coffee, or a smoothie. Its flavour is earthy and bitter, so it pairs best with something rich. Tonic herbs are traditionally enjoyed daily and consistently.
What should I look for in a quality ashwagandha?
The plant part stated plainly, a named preparation method, an extract ratio if it is an extract, withanolide content where disclosed, and independent purity testing.
Is ashwagandha the same as Indian ginseng?
“Indian ginseng” is a common nickname for ashwagandha, but the two plants are unrelated botanically. The nickname refers to ashwagandha’s role as a daily tonic in its own tradition.
Where can I buy ashwagandha?
Sun Potion offers ashwagandha as a cold-water extract of the root, shipped across the US from sunpotion.com in the signature cobalt blue glass jar. It is also available in a Travel Ally size and through select wellness retailers.
