Dhanyaka

What is Dhanyaka?

Dhanyaka is the classical Ayurvedic name for coriander, one of the most familiar plants in the world’s kitchens. It belongs to the Apiaceae family, the same botanical group as cumin, fennel and dill, and its parts have travelled from the spice jar to the medicine chest for a very long time.

The part most often meant by Dhanyaka is the Phala, the dried ripe fruit, which everyone knows as the coriander “seed”. These are the small, pale, round, lightly ridged spheres with a warm, citrus-like aroma. The fresh green leaves of the same plant, known in English as cilantro, are used too, along with the whole young herb.

The Sanskrit name is often linked to the word for grain or a store of grain, a fitting image for a small fruit that keeps well and is kept in every household. Classical texts also list a rich set of synonyms for it, including Dhaniya, Kustumburu and Chhatra, the last a nod to the plant’s umbrella-shaped flower head. In short, Dhanyaka is a single plant that gives two well-loved ingredients: the aromatic seed and the fresh leaf.

What Ayurveda uses it for

In the classical materia medica, Dhanyaka is valued as a gentle, aromatic digestive support and as a cooling dravya, meaning a substance understood to ease a sense of internal heat. It has long been a household spice given a place of honour among the herbs used for the everyday well-being of the digestion.

The Charaka Samhita places coriander among two notable groups of herbs. It appears in the Trishnanigrahana Mahakashaya, the collection of herbs traditionally used to settle excess thirst, and in the Shitaprashamana Mahakashaya, the herbs that relieve a sense of heat. That double listing captures the spirit of how Ayurveda sees it: a herb that both quiets thirst and cools.

Traditionally it is taken to support comfortable digestion and a healthy appetite, and it is a classic ingredient in cooling drinks and infusions. Later nighantu texts such as the Bhavaprakasha and the Raja Nighantu describe it as kindling the digestive fire, aiding digestion, and easing thirst and a feeling of heat, and they class it among the cooling digestive dravyas with a particular friendliness towards Pitta.

Its qualities, in plain words

Ayurveda describes every herb through a small set of qualities, and for Dhanyaka they paint a picture of something light, mild and cooling.

Its taste, or rasa, is mainly astringent and bitter, with a note of sweetness, especially in the fresh herb. Astringent and bitter tastes tend to feel drying and steadying, while the touch of sweet softens the overall impression.

Its qualities, or guna, are light and unctuous, so it sits easily and is not heavy on the system. Its post-digestive taste, or vipaka, is sweet, which is why a herb that tastes bitter and astringent still leaves a mild, settling after-effect.

The most interesting quality is its virya, or energy. Here the classics do not fully agree. The dried seed is described as heating in the Bhavaprakasha tradition, yet the fresh herb and several other sources call it cooling. In everyday practice it is widely treated as a cooling herb, in keeping with Charaka placing it among the herbs that calm thirst and heat. Its main actions, or karma, follow from this: it is deepana and pachana (it gently kindles and supports digestion), trishna-nigrahana (it settles thirst), and dahaprashamana (it eases a sense of burning or heat). It is also described as hridya, agreeable to the heart, and rochana, making food more palatable.

How it is taken

Because Dhanyaka is first and foremost a food, it slips easily between the kitchen and the classical dispensary.

The simplest form is the whole or powdered dried seed, the Churna, stirred into food or warm water. A very traditional cooling preparation is the Hima, a cold infusion made by steeping the crushed seed in water overnight and straining it in the morning, which draws out the herb’s gentle, cooling character without heat. It is also prepared as a Kwatha or Phanta, a decoction or hot infusion, and the fresh leaf is used as a juice or paste.

As a vehicle, plain water is the classic partner, which is why Dhanyaka Hima, the cold coriander-seed infusion, is such a well-known everyday preparation type. Coriander also appears among the many herbs gathered into large classical groups of formulations such as Dhanwantaram, where it is one voice in a wider chorus rather than the lead. In most of these settings it plays the role of a supportive, aromatic digestive spice.

Good to know

Dhanyaka is one of the mildest and most everyday of Ayurvedic herbs, which is exactly why it turns up so often in cooling drinks and simple digestive preparations. Traditionally it is taken with or around meals, when its role as a digestive and appetising spice fits naturally, and cooling infusions are often favoured in warmer weather or when a settling, thirst-easing drink is wanted.

Coriander is a very common food, so most people meet it daily without a second thought. Even so, anyone with a known allergy to coriander or to related Apiaceae plants such as cumin, fennel or celery should be careful, and medicinal amounts are a different matter from a sprinkle in cooking.

This entry describes the classical Ayurvedic understanding of the herb. It is not medical advice, and anyone who is pregnant, breastfeeding, taking medication or living with a health condition should speak to a qualified practitioner before using it in medicinal amounts.

Frequently asked

Is Dhanyaka the same as the coriander in my kitchen? Yes. Dhanyaka is the classical name for coriander, Coriandrum sativum. The dried seeds you cook with are the Phala referred to in the texts, and the fresh green leaves are what English speakers call cilantro.

Is it warming or cooling? The classics are not unanimous. The dried seed is called heating in some texts, while the fresh herb and several other sources call it cooling. In everyday practice it is generally treated as a cooling herb, which is why Charaka lists it among the herbs that settle thirst and ease a sense of heat.

What is a Hima, and why is it linked to coriander? A Hima is a cold infusion, made by soaking the herb in water overnight and straining it in the morning rather than boiling it. Dhanyaka Hima, the cold coriander-seed infusion, is a classic example of this gentle, cooling preparation type.
