Ajmoda (Celery Seed) Powder: Benefits, Uses and Precautions

Ajmoda powder, made from celery seed (Apium graveolens), is the simplest way to bring this carminative spice into Ayurvedic cooking, covered in our ajmoda reference article. It joins the family of digestive seeds already covered on this site: ajwain, cumin, coriander and fennel.

This article draws a clear line between two very different uses of the same plant: ground whole-seed powder for culinary and digestive use, and the standardized concentrated extract, the only form to have shown a measurable effect on blood pressure in a clinical trial.

Ground powder or standardized extract: do not confuse the two

Form	Context	Key takeaway
Ground whole-seed powder	Traditional culinary and digestive use	Very low intake of active compounds; no effect comparable to the clinical trial
Standardized extract in capsules	Used in the 2022 blood pressure clinical trial	A concentrated, controlled dose, taken alongside existing antihypertensive treatment — never a substitute

This distinction, already made in our reference article on ajmoda, matters: a sprinkle of seed powder on a dish, however tasty, comes nowhere near the dose tested in the lab.

What does the available clinical study show?

A randomized, triple-blind, placebo-controlled crossover trial by Shayani Rad, Moohebati, MohammadEbrahimi, Motamedshariaty and Mohajeri, published in 2022 in the journal Inflammopharmacology, tested a celery seed extract in hypertensive patients already on their usual treatment. The study, available on Google Scholar, reports a significant drop in blood pressure, along with favorable effects on fasting blood sugar and lipid profile, with a good tolerance profile over the trial's duration.

This result concerns a concentrated, standardized extract, taken alongside an existing medical treatment — not the seed powder as found in cooking, whose active-compound content is far more modest and variable.

How to use ajmoda seed powder in cooking?

• As a tadka: a half to one teaspoon of dry-roasted or oil-tempered seeds at the start of cooking, in legumes or root vegetable dishes.
• As a fine powder: mixed directly into a flatbread dough or a vegetable dish, for a milder flavor than whole seeds.
• As a digestive tea: a teaspoon of powder steeped for 10 minutes after a heavy meal, on the same principle as CCF tea with cumin, coriander and fennel.

How to choose a good ajmoda powder?

Favor a freshly ground powder over old stock — celery seeds lose their aroma quickly once ground. Opaque, airtight packaging better preserves the volatile essential oils responsible for the characteristic flavor. For a specific blood-pressure goal, only a standardized extract taken under medical guidance replicates the conditions of the available clinical trial — culinary powder cannot substitute for it.

Precautions and interactions

• Celery allergy: this is one of the most common food allergies, subject to mandatory labeling. Anyone allergic to celery stalk should avoid ajmoda in any form, including powder.
• Additive effect with antihypertensive treatment: documented for the concentrated extract; without supervision, this combination can cause low blood pressure.
• Pregnancy and breastfeeding: culinary use in small amounts poses no particular problem; the concentrated extract calls for the usual caution around little-studied herbs in this context.
• Diabetes or cholesterol treatment: seek medical advice before any concentrated extract, given the additive effects reported in the clinical trial.
