Suranjan (Colchicum): Mithi vs Talkh, and the Colchicine Poison Margin

Suranjan is the dried corm of Colchicum, the hermodactyl of the old pharmacies, and it is the one pansari drug that is literally the same poison as a prescription medicine: colchicine, the gout drug, with a famously narrow gap between a dose that works and a dose that kills. “Mithi” (sweet) suranjan is not a milder cousin, and the most dangerous thing a gout patient can do with it is add it on top of the colchicine their doctor already gave them. This page explains the two grades, what colchicine does, the poisoning pattern, and the drug combinations that turn a traditional joint remedy into an emergency.

What is suranjan, and what is inside it?

Colchicum is a small bulb-like plant that flowers from bare ground, yellow in the Himalayan species and lilac in the European one. The part sold is the corm, a swollen underground stem, dug, peeled, sliced and dried into pale, hard, irregular pieces. The yellow Kashmir plant, Colchicum luteum, grows wild in the temperate Himalaya and supplies most of what the subcontinent’s pansaris sell.

Every part of the plant contains colchicine, a bitter alkaloid that stops cells from dividing by jamming the scaffolding (microtubules) they need to move and split. In a gout flare, that same action stops white blood cells from swarming into the joint, which is why a purified, exact dose of colchicine has been a prescription gout medicine for two centuries. In a corm, the amount is unknown, and that single fact is the whole story of this page.

Mithi vs talkh: what “sweet” actually means

Unani books describe three grades: suranjan shireen or mithi (sweet), suranjan talkh (bitter) and a dark, inferior grade. The sweet grade is prized and prescribed more freely. Modern writing usually attaches the sweet name to Colchicum autumnale and the bitter one to Colchicum luteum, though several authors reverse this, and at the shop the names are applied by taste rather than by botany.

The point that matters: both grades contain colchicine. A laboratory method published from Hamdard University in 2015, built precisely to measure colchicine in Unani habb and capsule products, states plainly that colchicine is the main alkaloid in both the bitter and the sweet variety. Measurements of Kashmir Colchicum luteum found the highest colchicine in the corm, around two tenths of a per cent, with lower amounts in seeds, leaves and flowers. The published comparisons of the two varieties do not even agree which has more, which tells you the difference is small and inconsistent.

Why the margin is so thin

Colchicine has no clean line between a therapeutic dose, a toxic dose and a lethal one. The 2010 systematic review of colchicine poisoning in Clinical Toxicology found a high death rate once an acute intake passed about half a milligram per kilogram of body weight, and recorded fatal outcomes in adults after swallowing amounts in the range of a small handful of ordinary prescription tablets. Children have died from a few. The American prescribing label for the drug carries the same sentence in plainer words: fatal overdoses, accidental and intentional, have been reported in adults and children.

Now do the arithmetic nobody at the pansari does. A corm at two tenths of a per cent colchicine means a gram of powder could carry on the order of two milligrams of the poison, or half that, or double, depending on the plant, the season, the part and how it was dried. A heaped teaspoon of powder taken “for the joints” a few times a day is not a herbal dose. It is an unmeasured dose of a chemotherapy-class alkaloid.

The poisoning pattern, and why it fools people

Colchicine poisoning does not look like poisoning at first. The review above describes three overlapping phases.

1. Hours 10 to 24: the stomach phase. Nausea, vomiting, cramping belly pain and heavy, often watery diarrhoea. It looks exactly like food poisoning or gastro, so people drink water, take an ORS, and wait. Fluid loss can already be dropping the blood pressure.
2. Day 1 to day 7: organ failure. The bone marrow stops making blood cells, so infections take hold; the heart muscle, kidneys, liver and lungs can all fail; muscle breaks down; fits and confusion appear. Most deaths happen here, from heart failure, bleeding or overwhelming infection.
3. Week 2 onwards: recovery, if it comes. Hair loss starting about a week after the ingestion is typical. Survivors usually recover fully over weeks.

There is no antidote. Treatment is charcoal if the person reaches hospital within the first hour or so, then intensive support, and late arrival or existing kidney or liver disease makes death much more likely. So: vomiting and diarrhoea within a day of taking any suranjan product, especially with weakness, a racing heart or faintness, is a hospital visit now, packet in hand.

Interactions that turn a usual amount into an overdose

Colchicine is cleared by a liver enzyme (CYP3A4) and a pump in the gut and kidneys (P-glycoprotein). Anything that blocks them lets colchicine pile up. The prescription label and the toxicology review list the same culprits, and they apply with more force to a corm of unknown strength:

• Antibiotics: clarithromycin above all (deaths are recorded), also erythromycin. A gout patient on suranjan who is given a macrolide for a chest infection is the textbook disaster.
• Antifungals: ketoconazole, itraconazole, fluconazole.
• Transplant, heart and HIV drugs: ciclosporin and ranolazine; verapamil and diltiazem; ritonavir and the other protease inhibitors.
• Grapefruit juice: blocks the same enzyme; the label tells colchicine patients to avoid it.
• Statins and fibrates: atorvastatin, simvastatin, lovastatin and the like; colchicine plus a statin raises the risk of muscle breakdown, and many gout patients take both.
• Kidney or liver disease: slows clearance so much that the label forbids combining colchicine with any of the blockers above in those patients at all.

What tradition says, and the honest view

The honest view has three parts. The tradition is not wrong about gout: colchicine works in acute gout, which is why the drug exists. The corm is the wrong way to take it, because the dose cannot be known and the tablet does the same job measurably. And there is no evidence for suranjan in osteoarthritis, back pain, “uric acid” without gout or general stiffness, where its toxicity buys you nothing.

Gout itself is managed by diet, weight, fluids and prescribed medicine, and we cover the eating side properly in what to eat in the first 48 hours of a flare and uric acid and desi food. High uric acid with no symptoms is its own question, answered in this article.

Buying and labelling: what a buyer can and cannot know

A pansari’s suranjan powder has no colchicine figure on it, and no home test exists; taste only tells you the trade grade. Whole dried corm pieces are at least identifiable as Colchicum; powder could be anything. A DRAP enlistment number in Pakistan or a manufacturing licence in India means the maker is known, not that the colchicine content is standardised. Price is not the issue; suranjan is cheap, and a low price buys the same risk as a high one.

Suranjan: the questions people ask

The bottom line

Known: suranjan is colchicine in plant form, the sweet grade included, and colchicine has one of the narrowest safety margins of any common medicine. Tradition claims a gout and joint remedy, and for gout the molecule does work; the tablet simply does it with a known dose. Uncertain: how much colchicine is in any given packet, which is exactly why no home dose can be called safe. The main safety issue is doubling up with prescribed colchicine or mixing with the antibiotics, antifungals and statins that block its clearance, and the delayed, gastro-like start to poisoning that sends people to hospital too late.
