Charaka Samhita Kalpa Sthana Chapters 2-4: Jimutaka, Ikshvaku and Dhamargava - the Bitter Gourds of the Classical Vamana Pharmacy

📖 23 min read · Classical source: Charaka Samhita, Kalpa Sthana, chapters 1–4 · pages 573–580 of the Van Loon English edition

Most of the Charaka Samhita is organised the way you would expect a medical compendium to be organised — by principle, by body part, by disorder. Then you reach the Kalpa Sthana, and the filing system changes completely. Here the organising unit is not an idea and not a condition. It is a plant. One chapter, one plant, and everything the tradition had accumulated about what could be done with it.

Chapter 1 is Madanaphala. Chapter 2 is Jimutaka. Chapter 3 is Ikshvaku. Chapter 4 is Dhamargava. Read the four titles in a row and something jumps out: after the first, they are all gourds. Bitter, inedible, deliberately-not-dinner gourds, from the family that also gives us the cucumber and the pumpkin. Charaka gave three consecutive chapters of a medical classic to three members of the marrow family, and then counted the preparations at the end of each one like a man closing a ledger.

The Kalpa Sthana: the book of the Charaka Samhita where each chapter belongs to a single plant.

This article walks through those chapters in the order the text gives them, in plain English. If you want the wider frame first — how a classical Ayurvedic preparation is actually made, from the steeping to the cooking — we have written that up separately in our guide to Bhaishajya Kalpana and the making of classical medicines, and the Madanaphala chapter itself has its own long read in Madanaphala, the gentlest of the Vamana fruits. This one picks up where that one stops.

Where the Kalpa Sthana Sits in the Charaka Samhita

The Charaka Samhita is built in eight sections, called Sthanas. Sutra Sthana lays out the principles. Nidana Sthana handles the causes of disorders. Vimana, Sharira, Indriya and Chikitsa follow. Then comes Kalpa Sthana, and last, Siddhi Sthana. The word kalpa here carries its pharmacy sense: a preparation, a way of putting something together, a formulation. Kalpa Sthana is the formulary.

It runs to twelve chapters, and they split cleanly down the middle. The first six are the Vamana drugs — the plants used in the classical emetic procedure. The last six are the Virechana drugs, used in the downward-clearing procedure. Chapters 1 to 4 give you Madanaphala, Jimutaka, Ikshvaku and Dhamargava; chapters 5 and 6 add Vatsaka and Krtavedhana. Then the book turns and works through Shyama-Trivrit, Chaturangula, Tilvaka, Sudha, Saptala-Shankhini and Danti-Dravanti.

That structure tells you what the section is for. It is not a herbal in the browsing sense — it is the supply manual for two of the five procedures of Panchakarma. A physician who had decided on a course of action needed to know which plant, in which form, at which dose, carried in what. The Kalpa Sthana is where that information lived.

Madanaphala gets first place for a stated reason. In the Charaka Samhita, Sutra Sthana, Chapter 25 — the chapter that runs through the best drug in each class — Madanaphala is named the foremost of the emetic substances. Chapter 1 of the Kalpa Sthana then earns that ranking with sheer volume, closing with a count of 133 formulations. What follows in chapters 2, 3 and 4 is a step down in prestige but not in detail.

One point of orientation before we go in. The classical procedure these plants belong to is Vamana, and it was never a casual thing. It sat inside a long protocol — days of internal oleation, then sudation, then the procedure itself under supervision, then a graded re-feeding schedule afterwards. We have written about that whole apparatus in our guide to Charaka Sutra Sthana 15 and the preparation for Panchakarma. The Kalpa Sthana assumes all of it. It is the parts catalogue, not the manual.

Paryaya: Why Every Chapter Opens With Other Names

Each of these chapters begins the same way. Before a single preparation is described, the text lists a handful of alternative names for the plant. This device is called paryaya — synonym — and in classical Sanskrit scientific literature it is doing real work, not padding.

Why open with a name-list? Three reasons, and all of them are practical.

The first is regional. A physician trained in one part of the subcontinent and practising in another would meet the same plant under a different local name. A paryaya list is a translation table. Give five names and you have covered five markets.

The second is descriptive. These are not arbitrary labels — most classical synonyms encode a fact about the plant. Look at Ikshvaku's list. Lamba means long or pendulous, which is the shape of the fruit hanging on the vine. Tumbi is the ordinary word for the calabash. Pindaphala means lump-fruit. And katukalabu is the important one: katu is bitter or pungent, alabu is the calabash gourd. The name says the bitter calabash, and that single adjective is the whole safety instruction, built into the vocabulary.

Dhamargava's list does the same job. Mahajalini means great-netted, which is exactly what the dried fruit of a luffa looks like when the flesh is gone and the fibrous mesh is left — the thing sold in every bathroom aisle as a loofah. Rajakoshataki means the royal koshataki, marking it out as the senior member of a group of related gourds.

Paryaya: one plant, several names. Each name in the classical list encodes something about the thing itself.

The third reason is the least obvious and probably the most important. Misidentification was the great danger of classical pharmacy, and it still is. When the material is bitter, drastic and easy to confuse with a related edible plant, an ambiguous name can be dangerous. Five names, cross-referenced, narrow the target. The paryaya list is a redundancy check.

This same instinct runs through the wider tradition. If you want to see how systematically the texts sorted plant material by taste, potency and post-digestive effect, our guide to Dravyaguna and the Charaka Samhita's pharmacology lays out the framework these chapters are built on.

How the Madanaphala Kalpa Ends: Anupana and a Census

Our page window opens partway through the closing passages of Kalpa Sthana 1, and those closing passages are worth reading, because they set the pattern for everything after.

The first thing the text does is widen the range of carriers. Madanaphala, it says, should be administered combined with preparations such as badarasadava (a jujube conserve), raga, leha, modaka, utkarika, tarpana, panaka, meat soup, vegetable soup and wine — and these should be chosen "according to dosa, disease and inclination" (Ka1#25–26).

That final phrase is a small masterpiece of clinical writing. Three criteria, in order: the state of the doshas, the nature of the condition, and — third but explicitly named — what the patient actually likes. The classical carrier, or anupana, is chosen partly on palatability. A person who will not swallow the preparation is not being treated at all. We have looked at the anupana concept in more depth in the Bhaishajya Kalpana guide; here it is enough to notice that the text puts the patient's preference on the same list as the dosha assessment.

Then the chapter closes with a census. This is the Kalpa Sthana's signature move, and it is oddly moving once you notice it:

A tally, by dosage form, adding up to a stated total. Chapter 2 will do the same and land on 39. Chapter 3 will do it and land on 45. Somebody was keeping count, form by form, chapter by chapter, and thought the count was worth writing into the verse itself.

It is worth asking why. Partly it is a memory aid — an oral tradition that has to carry a formulary needs checksums, and a stated total tells a reciter whether anything has fallen out of the transmission. Partly it is a claim of completeness: this is the whole chapter, nothing withheld. And partly, one suspects, it is pride. Thirty-nine ways to prepare one bitter gourd is a scholarly achievement, and the man who compiled them wanted you to know the number.

Jimutaka Kalpa: Kalpa Sthana Chapter 2

Chapter 2 opens with the paryaya — jimutaka, garagari, veni, devatadaka — and then makes a claim about scope that is easy to read past (Ka2#4):

Note the conditional. Jimutaka does not act on all three doshas by itself; it does so when prepared with the respective drugs. The plant is a vehicle for direction, and the accompanying substances aim it. That is the logic of the whole formulary — a base material plus companions that steer it.

On sourcing, the text is brisk: collect plants grown in proper soil and possessing the right qualities, exactly as described in the Madanaphala chapter (Ka2#5). The Kalpa Sthana does not repeat itself. Collection rules — the right land, the right season, the right stage of growth — were set out once, and every later chapter simply points back.

Jimutaka, the subject of Kalpa Sthana chapter 2. Almost every preparation in the chapter is built on milk.

Milk as the default medium

What follows is a set of preparations sorted by which part of the plant you have and what condition it is in (Ka2#6). It reads like a dairy manual:

Five different dairy states — whole milk, gruel, cream, curd, soured curd — matched to five different states of the plant. The text distinguishes a hairy from a non-hairy variety and gives them different treatments, which is a botanist's distinction being used as a pharmacist's instruction.

Milk is the standing medium across all these chapters, and that is not an accident of taste. In the classical scheme milk is itself a substance with properties, described at length in its own varga. Vagbhata's treatment of milk, curd, buttermilk and ghee — what each does, and how they differ — is set out in our guide to the Kshira Varga of the Ashtanga Hridaya. When Charaka boils a bitter gourd in milk he is combining two active materials, not diluting one in a neutral liquid.

Then the dry-storage route (Ka2#7). When the fruit is old enough it should be dried, powdered well, and kept in a clean container. The dose is given as twenty grams in the modern rendering, taken with milk, indicated in disorders of Vata and Pitta. Three sentences and you have a shelf-stable churna with a storage rule, a dose and a carrier.

The chapter's remaining formulas pair the fruit with decoctions — guduchi, madhuka, the kovidaradi group, nimba and kutaja in one; the aragvadhadi group in another, specified for jwara arising from Pitta and Kapha together (Ka2#9–10). For fevers of Pitta with Kapha, or Vata with Pitta, the fruit is given with the juice of jivaka, sugarcane or shatavari (Ka2#12). And the chapter names its own best preparation (Ka2#13): jimutaka boiled with full-fat milk, the ghee extracted from that milk, and the ghee then cooked with a decoction of madhanaphala and the rest — a four-stage preparation ending in a medicated ghrita.

Then the count (Ka2#14–15): 6 preparations in milk, 1 in suramanda, 12 other formulas, 7 in decoctions of the aragvadhadi group, 8 in measured doses, 4 in the jivaka group, 1 ghrita. Thirty-nine formulas, from one bitter gourd.

Suramanda: Charaka's Rare Alcohol Extraction

Tucked into chapter 2 is a single instruction that stands out from everything around it (Ka2#8). The fruit is to be dipped in suramanda — the clear upper portion of sura, a fermented preparation, rendered by the translator as absolute alcohol. It is then pressed and filtered, and the resulting liquid is used in conditions marked by Kapha, in kasa (cough), in pandu (the classical pallor disorder) and in rajayakshma (the classical wasting disorder).

The translator adds a note in the margin, and it is the kind of note worth stopping for: this is one of the very few instances in the whole Charaka Samhita of the technique we would now call an alcohol tincture.

Whether or not the classical authors could have explained why, the practice encodes a real distinction. The gourd family's bitter principles are not equally soluble in every medium, and a maker who has watched enough extractions learns which liquid pulls the most out of which material. Charaka's five standard water-based methods are set out in our guide to Swarasa, Kalka, Kwatha, Hima and Phanta — the Panchavidha Kashaya Kalpana. Read that first, then come back to this line, and the oddity of it becomes clear.

Chapter 3 repeats the technique, almost in passing: the fifth preparation of Ikshvaku is made with the green-pale fruits in suramanda (Ka3#6). Chapter 4 does the same for Dhamargava — four preparations in milk, and then "the fifth in wine, as said earlier" (Ka4#7). So the tincture is not a one-off. It is a slot in a standard sequence: four in milk, one in spirit, then the rest.

Ikshvaku Kalpa: Kalpa Sthana Chapter 3

Chapter 3 is the longest and most varied of the three, and its subject is the plant most likely to be sitting in a reader's kitchen — in its sweet form. Ikshvaku is the calabash, Lagenaria siceraria: the bottle gourd, lauki, dudhi, ghiya. The classical chapter is about the bitter kind, and the synonym list says so — katukalabu, the bitter calabash.

The indications are given up front (Ka3#4): useful as an emetic in those suffering from kasa (cough), shwasa (laboured breathing), visha (poisoning), chhardi (vomiting) and jwara (fever), in those weakened by Kapha disorders and subject to fainting attacks.

Ikshvaku, the calabash of Kalpa Sthana chapter 3. The classical chapter concerns the bitter variety, katukalabu.

The measured fistful

The first preparation contains one of my favourite pieces of classical measurement (Ka3#5). Tender leaves from a plant not yet in flower are to be taken "by the fist till the root of the index finger" and boiled in 640ml of milk.

That is a dose specified by hand. Not a weight, not a volume — a quantity you can grip, defined by where on your own finger the bundle reaches. It is reproducible without any equipment at all, and it scales with the person doing the measuring. The Kalpa Sthana is full of this kind of thing, and it is one of the reasons the formulary survived: the instructions work in a village with no scales.

From there the chapter fans out. Four preparations are made with the flowers and other parts in milk, exactly as in the Jimutaka chapter. A fifth uses the green-pale fruits in suramanda. Then the specific formulas begin:

The hollowed-fruit preparation deserves a second look. Take an old calabash, scoop out the pulp, fill the empty shell with milk, and leave it until the milk curdles. The gourd is not an ingredient here — it is the vessel, and the vessel is doing the work. Whatever sits in the shell wall passes into the milk during the setting. That is a container being used as a reagent, which is a genuinely clever piece of process design.

The inhaled preparation

Then there is Ka3#11, which is one of the odder sentences in classical Indian medicine: a person suited to fine perfumery is made to vomit by inhaling a garland powdered with the dried juice and flowers of Ikshvaku.

An emetic administered through the nose, delivered on a flower garland, prescribed specifically for someone accustomed to good perfume. There is a clinical judgement inside the strangeness — for a patient who will not tolerate the taste, or cannot keep anything down, you change the route of administration. The route follows the patient. The classical literature on nasal administration is much larger than this one line suggests, and we have covered it in our guide to Nasya, the Charaka Samhita's nasal therapy.

The escalating course

Ka3#13 describes something different again: fifty seeds, increased by ten at each step, dipped separately in decoctions of the phaladi group, then pressed, filtered and taken. That is not a formula. That is a schedule — a graded course with a starting quantity and a fixed increment, titrated upward over successive administrations.

The chapter closes with its census (Ka3#21–23): 8 preparations with milk, 3 with suramanda, curd water and buttermilk, 1 by inhalation, 1 with sesame paste, 1 with oil, 6 gradually increasing ones in the phaladi group, 1 with ghee, 9 with decoctions of the madhukadi group, 8 as vartikriya, 5 as linctus, 1 as mantha, 1 with meat soup. Forty-five formulations "described well for the welfare of the people."

Why the Bitter Calabash Was Never Filed as Food

Here is the thing worth carrying away from chapter 3, and it is a point about filing.

The Charaka Samhita has a place for vegetables. The Sutra Sthana works through the food groups at length — grains, pulses, meats, vegetables, fruits — assessing each for its qualities and its effects. The calabash, in its ordinary sweet form, is a food, and it is treated as one there.

But katukalabu, the bitter calabash, is not in the vegetable chapter. It is in the Kalpa Sthana, in the emetic group, alongside a plant whose entire purpose is to make a person vomit under supervision. The classical tradition looked at the bitter variety of an ordinary vegetable and filed it, deliberately, with the drastic medicines.

What is striking is the agreement across two thousand years. A modern advisory and a classical formulary reached the same conclusion by entirely different routes: this plant, in this form, is not food. Charaka reached it by taste and by observed effect, and encoded the finding in a name — katu, bitter, glued to alabu, calabash, so that the warning travelled with the word.

The classical texts were also explicit that these plants belonged inside a controlled procedure and not in a kitchen. Vamana in the classical protocol involves preparation over days, supervision during, and a graded re-feeding schedule after. The plants in Kalpa Sthana 1 to 6 were never intended to be used casually, by anyone, at home. That is not a modern gloss added for caution. It is what the surrounding literature says.

There is a general lesson in it about how to read these chapters. The Kalpa Sthana is a professional document written for practitioners inside a system that included training, assessment and supervision. Read as history and as pharmacology, it is fascinating. Read as a set of instructions, it is dangerous. The tradition itself drew that line.

The Doneness Test: How Charaka Knew a Leha Was Ready

Kalpa Sthana 3 contains one more thing that deserves its own section, because it is the sort of detail that separates a real working manual from a compilation of claims.

The formula at Ka3#16–17 is elaborate. Take 160 grams of Ikshvaku seeds in the modern rendering, boil them with a decoction of bilva root, and filter. To that add phanita (concentrated cane juice) at one-third part, the seeds at one part, ghee at one part, and at one-sixth part a paste of dhamargava, jimuta, krtavedhana and kutaja. Cook the whole thing down over a mild fire, stirring with a ladle, until it becomes a linctus.

And then — the part that matters — the text tells you how to know when it is done:

The paka lakshana: a physical endpoint test for a cooked preparation, described in the verse itself.

This is a paka lakshana — a sign of correct cooking. Drop a little of the paste into cold water. If it draws into a thread and holds together rather than clouding away, the cooking is complete.

Confectioners still use exactly this test. The thread stage of a sugar syrup is judged the same way, by eye and by feel, and the number of threads tells you the stage. What Charaka has written into the verse is a physical endpoint criterion that requires no timer, no thermometer and no prior experience of this particular formula. It transfers. A maker who has never prepared this linctus before can still tell when it is ready.

The instruction to stir with a ladle over a mild fire belongs to the same logic. Both are process controls, and both survive translation into any kitchen, in any century. This is what a formulary looks like when it is written by people who actually made the things.

Dhamargava Kalpa: Kalpa Sthana Chapter 4

Chapter 4 opens the way the others do, with the paryaya: karkotaki, kothaphala, mahajalini, rajakoshataki (Ka4#3). Then the indications (Ka4#4): gara (artificial or compounded poison), gulma, udara, kasa, Vata situated in the seat of Kapha, Kapha located in the throat and mouth, disorders arising from accumulated Kapha, and other stable and severe conditions.

"Other stable and severe diseases" is the phrase that places Dhamargava. Where Madanaphala is the gentle one, this is the plant reached for when a condition is entrenched.

Dhamargava, the mahajalini or great-netted gourd of Kalpa Sthana chapter 4.

Collection follows the same back-reference: fruits, flowers and tender leaves, gathered as said earlier (Ka4#5). Then the preparations, and by now the sequence is familiar:

• Ka4#6 — the juice of tender leaves, dried, made into pills, taken with a decoction of the kovidaradi group and madhuka. A dried-juice pill: concentrate the fresh juice, dry it, form it, and you have a portable dose that keeps.
• Ka4#7 — four preparations in milk of the flowers and the rest, as described earlier; and the fifth in wine, as said earlier. The standard slot, filled again.
• Ka4#8 — for gulma, udara and Kapha disorders: take old dry fruits, scoop out the mushy seed-bearing pulp, discard the skin and the seeds, steep the pulp overnight in a decoction of madhuka with jaggery, and give it the next morning with the kovidaradi drugs.
• Ka4#9 — for chhardi and hridroga of the Kapha type, the fruit is taken mixed with food.

That overnight steep at Ka4#8 is worth naming, because it is a technique in its own right. Soaking a material in a liquid so that the liquid's properties enter it is called bhavana, and it is one of the fundamental operations of classical pharmacy — repeated, sometimes dozens of times, to build up potency in a solid. Here it appears in its simplest form: one overnight steep in a sweetened decoction, which also softens the harshness of a drastic material.

And Ka4#9 is the gentlest instruction in these four chapters. Mixed with food. No procedure, no supervision-heavy protocol, no measured escalation — just the fruit taken with a meal. The Kalpa Sthana has a full range, and it does not use the heaviest tool for everything.

A Short Glossary of the Sanskrit in These Chapters

What These Chapters Are Not

Three things, stated plainly.

These chapters are not a set of instructions for a reader at home. They describe a professional procedure that the classical literature surrounds with preparation, supervision and aftercare. The plants involved are drastic by design. Reading about them is history; acting on them is not something this article is offering.

They are not a claim that any of this has been established by modern clinical evidence. What the Kalpa Sthana records is what a long tradition of practitioners believed and did. That is genuinely valuable as intellectual history and as pharmacognosy. It is not the same thing as a trial.

And they are not connected to anything on our shelf. Ayurveda Hub does not sell Jimutaka, Ikshvaku, Dhamargava or Madanaphala, and does not sell any emetic preparation. The classical names in this article appear here purely as subjects of scholarly discussion.

From the Ayurveda Hub Shelf

The counting verses that close each Kalpa Sthana chapter tally preparations by their form — so many as a powder, so many as a spoonable paste, so many as a formed sweet, so many as a drink. Those categories long outlived the specific plants of these four chapters, and they are still the shapes that traditional preparations take today. Three things we make sit in three of those old categories.

All three are traditional everyday preparations, valued in Ayurveda for nourishment, strength and vitality, and made to be taken as part of an ordinary daily routine.
