Dirmana (Shih Armani)

What is Dirmana (Shih Armani)?

Dirmana, also called Shih Armani, is a dried flower head. It comes from Artemisia maritima, a small grey shrub. The shrub grows on salt flats and dry steppe.

In English it has long been called santonica or sea wormwood. Persian and Unani medicine use it as a single drug. The main use is to drive out worms in the gut.

This is not a gentle digestive herb. Its main active chemical is santonin. Santonin kills worms, but it also poisons people.

It caused many bad poisonings when it was a common medicine. Some of those cases ended in death.

Here is the short verdict on the evidence. The traditional record is long, and it crosses several medical systems. But no modern controlled human trials support it.

Its safety record was bad enough that most countries stopped using it. Traditional use, here and anywhere else, is not proof that something works. It is not proof that it is safe either.

We describe Dirmana because you may still meet it. It turns up in Unani formulas, old texts and imported worm remedies. We do not suggest a home dose.

Safe, well-tested medicines for gut worms now exist.

How does Dirmana (Shih Armani) work?

Santonin seems to paralyse roundworms. The bowel can then push them out. Lab and animal work records this effect.

Does it clear worms in people at a dose that does not harm them? Modern testing never settled that.

The same chemical also acts on the brain. It acts on the optic nerve too, the nerve that carries sight. That is the likely reason overdose brings yellow-tinted vision, then confusion and seizures (fits).

Classical Unani theory calls Dirmana a hot and dry drug. It is said to dry 'phlegm', warm the gut and expel worms. That is the tradition's own reasoning, not a tested mechanism.

What forms does Dirmana (Shih Armani) come in?

Traditional forms include: - Dried flower heads, whole or powdered - A powder blended into honey or a jam-like paste (majun) - A water decoction (the herb simmered in water) - Pressed lozenges, used in older pharmacy practice - Purified santonin tablets, made in the 1800s and 1900s and now withdrawn in most countries

Modern supply is not reliable. Herb sold as sea wormwood is sometimes another Artemisia species. The label does not state the strength.

Where it comes from:

Dirmana travelled far. Greek and Roman writers knew a worm-expelling wormwood. Arabic and Persian doctors listed Shih Armani among the standard single drugs.

European traders sold the same flower heads for centuries. They called them 'semen contra'.

Santonin was isolated from the plant in 1830. It then became a mainstream worm treatment worldwide. Poisonings in children, including deaths, were reported steadily through that period.

Safer medicines arrived in the mid-1900s. Santonin was then dropped from most pharmacopoeias (official drug lists). Unani practice still records the drug, but it is used far less than it once was.

What does Dirmana (Shih Armani) help with?

• Roundworm infection (Ascaris) in the gut: This is the classic reason for using Dirmana. Unani, Persian and European practice all used it this way. Old clinical reports describe worms passed after santonin. Lab work shows that santonin paralyses roundworms. Modern proof is missing. No controlled human trial compares Dirmana with a dummy pill or with today's worm medicines. Those modern medicines are tested, cheap and far safer. So there is no practical reason to choose this one.
• Pinworm or threadworm infection: Traditional texts list Dirmana for small thread-like worms too. The evidence here is weaker still. It mostly repeats the roundworm reasoning. Pinworm is easy to treat with a tested medicine from a pharmacy. Careful hand and bedding hygiene helps as well. Using a herb that holds santonin is a poor trade of risk for benefit.
• Gas, bloating and cramping blamed on worms: Unani sources say Dirmana warms and dries the gut. They use it for wind and griping pain when worms are suspected. No trial evidence backs this use. Bloating has many causes, and most are not worms. See a doctor for a diagnosis first. Do not treat a guess.
• Poor appetite linked in tradition to worms: Older accounts link gut worms with a thin child who is hungry but not eating. They advise worm drugs to bring back appetite. That is traditional reasoning, not tested fact. No human trial shows that Dirmana improves appetite. Lasting appetite loss or weight loss needs a medical check. It does not need a home worm remedy.

What are the side effects of Dirmana (Shih Armani)?

• Yellow-tinted vision (objects look yellow), a classic sign of santonin poisoning
• Blurred vision or trouble seeing colours
• Headache and dizziness
• Nausea, vomiting and stomach cramps
• Diarrhoea
• Dark or scanty urine
• Kidney irritation
• Liver injury (damage to the liver)
• Confusion and agitation
• Seizures (fits)
• Death after large or repeated doses, reported mostly in children

Good to know:

Mild stomach upset is common. The serious effects are not rare curiosities: yellow vision, seizures and deaths were reported often enough in the 1800s and 1900s that santonin was eventually withdrawn from ordinary use.

Children are at the highest risk, partly because they were dosed most often and partly because a small body reaches a toxic dose quickly.

Treat yellow vision as an emergency signal. It means the dose has already reached the nervous system, and seizures can follow.

Options to discuss with a clinician

Worm infections and digestive upset both have routes that have been studied far more carefully than this plant — and each one belongs in a conversation with a doctor, pharmacist or qualified practitioner rather than being started on your own.

**If you think you have worms (pinworm, threadworm or roundworm):** this needs confirming before anything is taken. A GP or pharmacist can arrange a simple test and discuss licensed anthelmintic (worm-killing) treatment, which is well-tested, measured by weight and often extended to the whole household. Many people who suspect worms turn out to have something else entirely, which is another reason to get it looked at.

**If the real problem is gas, bloating or cramping:** options worth raising with a clinician or herbalist include Peppermint Oil, Fennel, Ginger, a dietitian-supervised Low-FODMAP Diet, Probiotics (Lactobacillus plantarum P8) or Bacillus Coagulans. Ask which fits your particular pattern of symptoms.

**If appetite is poor:** that deserves a proper look at the cause — thyroid, mood, medication, infection — before anything herbal. Ginger is sometimes discussed for queasiness; your doctor can say whether it is relevant to you.
