What Is Kshira-paka? How a Goat-Milk Ayurvedic Face Oil Is Made

Two bottles can both say goat milk and mean different things. This is how the classical milk-and-oil method works, and what to ask before you buy.

Kshira-paka is the classical milk-and-oil method of making a medicated oil, a Taila: herbs are cooked slowly in an oil base with milk as the liquid, and the cooking carries on until the water has gone, after which the medicated oil is strained off. In Ayurvedic skin care, goat milk can be used this way, as the cooking liquid of a facial oil, so what goes into the bottle is an oil, not a milk preparation.

Goat milk can play two quite different parts in a facial oil. In one, a milk powder or extract is stirred into an oil that is already made, which is a faster process and a perfectly legitimate one. In the other, the milk is the liquid the herbs cook in, together with the oil, so it is part of the making rather than an ingredient added at the end. The words on the pack can read the same either way. Our own goat-milk oil, made the second way, is HerbOcean Soundarya Tailam, an AYUSH-licensed Ayurvedic medicine for external use, traditionally used to support healthy, comfortable, even-looking skin, and one that dry and mature skin tends to accept well. It is made by the goat-milk Kshira-paka method (the classical milk-and-oil method), in which the herbs are simmered with goat milk in a sesame base until the water has evaporated and only the medicated oil remains.

Key takeaways

• Kshira-paka is the classical milk-and-oil method: herbs, milk and an oil base are cooked together over a low fire until the water has gone, and what is strained off is a medicated oil.
• An oil cooked with milk belongs to Sneha Kalpana, the classical group of medicated oils and ghees. Ksheerapaka is a different preparation altogether: a medicated milk, taken by mouth.
• Goat milk is the cooking liquid and the largest single input, larger than any herb. Its water is driven off in the cooking, and more goat milk goes in than oil comes out.
• In Soundarya Tailam, the saffron, Kesar, goes into the finished oil after the cooking has ended and is left to steep there.
• On a pack, goat milk can mean milk cooked into an oil, milk stirred into a finished oil or milk in a soap bar, and the front of the pack may not say which.

What Does Kshira-paka Mean in the Classical Texts?

The answer to kshira paka kya hota hai starts with telling two preparations apart, because the classical literature uses milk in more than one place. The Sharngadhara Samhita describes a preparation called Ksheerapaka, in which a herb is simmered with milk and water until the water has gone and the milk remains. It sits in Madhyama Khanda 2 of that text, and what comes out of it is a medicated milk, taken by mouth, not an oil.

The chapter that governs a medicated oil is a different one. Sneha Kalpana, the oil and ghee chapter, is Madhyama Khanda 9. There a fat is cooked together with a herb paste and a liquid, and that liquid, the drava dravya (the cooking liquid), may be water, water in which herbs have been boiled down, a juice, curd or buttermilk. It may also be milk.

So when we say goat-milk Kshira-paka, we mean a Sneha Kalpana oil whose liquid is goat milk, Ajadugdh. The name says what happens in the vessel: herbs cooked with milk, in oil. For the textual rule behind a facial Taila, though, the place to look is the Sneha Kalpana chapter, not the Ksheerapaka section.

Goat milk can turn up in four different things. A Kshira-paka Taila for the face is a leave-on oil. Ksheerapaka is a medicated milk, taken by mouth as a physician directs. An oil with milk powder or extract stirred in after making is a finished oil with one more ingredient. And goat milk soap is a rinse-off bar, lathered and washed away. Only the first is an oil with milk as its cooking liquid.

How Is a Kshira-paka Taila Made, Step by Step?

Three things go into the vessel, and all three go in together. The kalka is the herb paste, and in Soundarya Tailam it holds nine ingredients in equal measure: Manjistha (Indian madder), Mulethi (liquorice), Raktchandan (red sandalwood), Palash flower (flame of the forest), Vatt (bargad or banyan bark), Priyangu fruit (beautyberry), Laksha (lac, a resin of insect origin), Daruhaldi (Indian berberry) and Nagkesar (Mesua ferrea). The sneha, the fat, is Til tail, sesame oil, and the drava dravya is goat milk. Lavender, rose and mogra oils complete the formula, along with Kesar, which is saffron.

Then it is cooked: not milk first and oil afterwards, but all three together, over a low fire, slowly. What the maker waits for is the water to leave, and the chapter gives signs to know it has. A pinch of the herb paste dropped into the flame crackles while moisture remains and burns silently once the water has gone. Froth rises on the surface as a Taila finishes, while for a ghee the sign runs the other way and the froth settles. And the paste, rubbed between two fingers, rolls into a wick rather than smearing.

Take the oil off too early and some of its water stays behind, and water left in an oil hastens rancidity, with light and air also playing a part. Leave it too long and the herbs scorch. Then the oil is strained, and only the oil goes forward. The bulk of the milk is not in the bottle, because its water has been cooked away. All of this describes manufacture, and it is not a home recipe.

Why Does More Goat Milk Go In Than Oil Comes Out?

For Soundarya Tailam, more goat milk goes into the vessel, by volume, than finished oil comes out of it. Goat milk is the largest single input in the formula, larger than any herb in it, and its water leaves during the cooking. That proportion follows our formulation sheet, and the classical oil chapter sets the liquid higher again, at four times the fat. The point is not the volume, though. It is what the volume is for.

Milk is not simply water. It is an emulsion, a watery phase carrying fat and milk proteins, and with the oil, the vessel holds more than one kind of solvent while the cooking runs. A plant does not hand everything over to a single solvent either: some of what sits inside a herb is happier in fat and some of it in water, and a long, slow cook gives the transfer time to happen.

That is a modern pharmaceutical reading, set out in a 2011 review that calls its own argument a hypothesis. The texts permit milk; they do not explain themselves in the language of solubility. That much milk for the oil it yields is also a real cost of making it this way.

When Does the Saffron Go Into the Oil?

Not every ingredient goes into the hot part of the process. In Soundarya Tailam the oil is cooked and finished first, and only then is the Kesar added to it and left to steep.

Recipes differ on this. A saffron oil in the Ashtanga Hridaya cooks its saffron in, while a modern Hindi commentary on the Sharngadhara Samhita, writing on Narayana Taila, quotes a verse that adds Kesar and other fragrant materials once the oil is off the fire. So the timing is a fact about how our oil is made, and both orders are on record. Two oils can print the same ingredient list and still have been made in a different order, which is one more thing you can ask about before you buy.

Why Does a Goat-Milk Taila Suit Dry Indian Skin?

There are three reasons, and each is about your skin, the air around it or the water you wash with. The first is that on melanin-rich skin, a spot that heals can leave a flat brown mark, the change dermatologists call post-inflammatory hyperpigmentation (PIH). In a 2016 study, dermatologists in seven Asian countries checked 324 people with acne for these marks. Over half had them, and in over half of the patients they had stayed a year or longer.

If you want the reason behind those marks, read why a pimple leaves a brown mark. An oil that stays on the skin asks for no scrubbing, which matters on skin that marks. The second reason is dry air: when the air turns dry and room heaters run for hours, the skin loses moisture, and a leave-on format suits skin in that state.

The third is the water your face is washed with. Samples of groundwater from South West Delhi have tested hard, and where a building there runs on a borewell, that is the water that reaches your washbasin. In one UK study of 80 participants, forearm skin rinsed in hard water kept extra cleanser on its surface, and that leftover cleanser increased the water lost through the skin and caused irritation, particularly in people with atopic eczema who carry an inherited filaggrin gene change. If you are curious about goat milk in a cream, read why Ayurveda reaches for goat milk on dry skin.

Milk and oil in one bowl is nothing new in an Indian home. Ubtan, hair oiling, abhyanga (classical full-body oil massage), a spoon of milk in a besan paste: each of them puts milk or oil, sometimes both, on skin. What the classical method does is take the same two materials and cook them together slowly, in a way the Sharngadhara Samhita says should not be finished in a single day.

How Can You Tell a Cooked Goat-Milk Oil From One With Milk Added?

You cannot see manufacture from the outside of a bottle, so ask. Ask whether the milk is an ingredient or a process. Ask when the saffron went in. Ask what the liquid was, in the sense the classical chapter means: water, a herbal liquid, a juice or milk. Those three answers will tell you more than anything printed on the front of the pack.

Soundarya Tailam is made the cooked way, with goat milk as its liquid. It is made in-house at our GMP-certified unit in Bawana, Delhi, under AYUSH Licence No. DL-474 A&U, and built on the 40-year Ayurvedic formulation legacy of Vaidya Shri Ram Prakash Ji. You will also find goat milk in HerbOcean Soundarya Cream, a rich saffron repair cream with bargad (Vatt) bark on a goat-milk and coconut base, with shea and kokum butters. Kshira-paka is the method of the Tailam. We make a second face oil as well, and if you are deciding between the two, start with choosing between our two Ayurvedic face oils.

What Does the Method Tell You, and How Is the Oil Used?

Cooking herbs into oil with goat milk over a low fire tells you something true and specific about an oil: how it was made, and what it costs to make it that way. How your own skin takes to it is what the patch test is for.

For Soundarya Tailam, the product page sets out how to use it. At night, on clean, slightly damp skin, press a few drops between the palms and pat over the face and neck. Very oily or actively breaking-out skin may prefer a lighter option. HerbOcean does not manufacture a sunscreen, and nothing in the range replaces one, so your sun protection stays a separate step. If you also use a cream, the morning and night order shows where the oil and the cream each go. If you would rather start small, the same oil comes as a Soundarya Tailam 10 ml trial.

Patch-test on the inner forearm 24 hours before first use and discontinue if irritation occurs; avoid the eye area. For external use only. Avoid it if you are allergic to sesame, goat milk or a listed botanical. If pregnant or breastfeeding, check with your doctor. Goat milk is used in the making, and we cannot promise the finished oil is free of milk protein, so a diagnosed milk allergy calls for caution. It is also not vegan, and the Laksha in it is a resin of insect origin, which matters if you avoid animal-derived ingredients.

Two things call for a doctor rather than an oil. Sudden swelling of the lips, mouth, tongue or throat, or difficulty breathing, with or without a raised, itchy rash, is a medical emergency, so stop and get help immediately. And if a patch of skin is growing or changing colour or texture, or keeps itching, bleeding or crusting for more than four weeks, show it to a dermatologist. The same goes for a new mole, or an old one that has started to change.

The Slow Steps, Left In

A Kshira-paka Taila is an oil made by the method of the classical oil chapter, with the slow steps left in: herbs, milk and oil cooked down together over a low fire, and the oil strained before it is bottled. That is something you can now ask about in specific terms.

Soundarya Tailam is the oil we make this way. And if you add anything new, keep it to one concern, one product, so your skin has a single new thing to get used to at a time.
