Bazr al-Jirjir is the seed of the salad rocket plant (Eruca sativa), used as a single drug in Persian and Unani medicine. It is best known in that tradition as a warming seed given for low sexual desire, sluggish digestion and poor urine flow.
It is a single drug, not a mixture: one plant, one part, the seed. The leaf of the same plant is the rocket or arugula you eat in salads, but the seed is stronger tasting and more concentrated in mustard-like compounds.
Honest verdict on the evidence: the traditional record is long and consistent, but we could not find published human trials that test rocket seed for any of these uses. Traditional use tells you what healers have done for centuries; it is not proof that the remedy works, and that distinction applies to everything said about this seed below.
Nobody has shown, in people, how or whether Bazr al-Jirjir works.
The leading idea is that the seed's mustard-oil compounds irritate tissue slightly and increase blood flow, which is how classical writers explained its reputation as a warming and stimulating drug. Laboratory and animal work has looked at effects on sperm counts, stomach lining and blood sugar in rodents.
Animal and test-tube findings do not carry over reliably to people. Treat any explanation of how this seed works as an idea that has not been tested in humans.
You will most often meet Bazr al-Jirjir in these forms:
Whole dried seed, sold loose by Unani and Middle Eastern herb suppliers.
Coarse seed powder, stirred into water, milk or honey. This is the classic Unani way to take it.
Cold-pressed seed oil (jamba or taramira oil), used mainly on the skin and scalp in South Asia rather than swallowed.
Compound Unani preparations where rocket seed is one ingredient among several. Those are different products with their own risks and are outside the scope of this page.
Rocket seed has a documented place in Greco-Arabic medicine going back roughly two thousand years.
Dioscorides described the seed in the first century, and later Persian and Unani writers including Avicenna listed it among the warming seeds given for weak desire and slow digestion. The same use carried into South Asian Unani practice, where taramira seed and its oil are still sold.
It remains a common bazaar item today, more as a household remedy and a source of pressed oil than as a prescription drug.
See a doctor if you get a rash, swelling of the lips, tongue or face, or any trouble breathing after taking it — stop straight away and get help fast.
Book an appointment if you notice a swelling in the front of your neck, unusual tiredness, weight gain or feeling cold all the time, as these can be signs of a slow thyroid gland.
Also see a doctor rather than treating yourself if erection problems or low desire are new or getting worse, if you are passing much less urine than usual or swelling up, if you have stomach pain or black stools, or if a cough lasts more than three weeks.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Bazr al-Jirjir is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
