Nalpamaram: The Four Ficus Barks of Ayurveda

Nalpamaram is the classical Ayurvedic group of four Ficus barks, its name meaning simply the four trees. The four are Nyagrodha, Udumbara, Ashvattha and Plaksha, and their barks are astringent, cooling and classed as varnya (complexion-tending). The tradition uses them together, mostly outwardly, as a cornerstone of its care of the skin and the complexion.

What it is

Nalpamaram is not a single herb but a group, and that is the whole idea. The name comes from Malayalam, joining nalu, four, with the word for trees, so it means the four trees, or the four barks. What binds the four together is that they are all Ficus trees, kin to one another, and that their barks share a cooling, astringent, skin-tending character.

These four are the Ficus members of a wider classical grouping, the Panchavalkala, the five barks, an old and much-used family of astringent barks. Nalpamaram gathers the four figs of that family and uses them as one preparation, most often for the skin.

The four barks

Each of the four is a well-known tree of the Indian landscape, and each carries a Sanskrit name the texts use.

Nyagrodha is the banyan, Ficus benghalensis, the great spreading tree of the roadside. Udumbara is the cluster fig, Ficus racemosa. Ashvattha is the sacred fig, or peepal, Ficus religiosa, the tree under which the tradition sets so many of its stories. Plaksha is Ficus microcarpa, sometimes given as a close relative. All four belong to the mulberry family, the Moraceae, and it is the bark of each that Ayurveda uses.

Their kinship is not just botanical. In the classical reading, the four barks share a taste and a direction, which is why they are trusted to work together as a single, cooling, astringent group.

Its classical qualities

Ayurveda describes every substance by a short list of qualities, and the four barks of Nalpamaram share theirs closely.

Their taste, the Rasa, is astringent (kashaya), the taste the tradition links most with toning and firming tissue. Their qualities, the Guna, are light and dry (laghu, ruksha), and their potency, the Virya, is cooling (shita). After digestion the Vipaka finishes pungent (katu).

This gathering of astringent and cooling qualities is exactly what makes the group a skin preparation. The texts class the barks as varnya, complexion-tending, and as kaphapittahara, settling both Kapha and Pitta among the three Dosha (the constitutional forces). Their cooling lean makes them most at home where the skin runs hot or uneven, a quality Ayurveda reads as surfacing Pitta, which you can read about on the Pitta dosha page, and their drying, astringent side suits a damp, Kapha tendency, covered on the Kapha dosha page.

What the tradition uses it for

Nalpamaram is, above all, a preparation for the skin. Being astringent, cooling and varnya, the four barks are the tradition’s classic choice to cool, tone and tend the skin and to support an even, clear complexion in classical terms. This puts them in the same company as other complexion-tending substances such as Amalaki.

The barks are used chiefly outwardly, as a paste, a cooling wash or, most famously, cooked into a medicated oil. Because their character is cooling and firming rather than forceful, they belong to the gentle, tending side of Ayurvedic skin care, the kind of preparation used regularly and lightly. Read plainly, this is classical skin care, not a remedy aimed at any named condition. Nalpamaram also appears within many named formulations, where its barks lend their cooling, astringent quality to the whole.

How it is used

There are three classical forms. The barks are powdered into a Churnam and made into pastes for the skin. They are boiled into a Kashaya (decoction) and used, cooled and strained, as a gentle wash. And they are cooked into medicated oils, above all Nalpamaradi Thailam, the oil of the four barks with turmeric, which in Kerala is often prepared in a coconut-oil base and called a keram.

In all of these the use is external and sparing: a little paste, a cool wash, or a few drops of the oil smoothed onto the skin. Because the barks are astringent and the oil can be staining where turmeric is used, a small amount is the classical instinct. Any internal use of the barks belongs under the care of a qualified practitioner.

Good to know and cautions

Nalpamaram is a cooling, astringent, drying group, which is its strength for the skin but also the reason for a little care: very dry skin may prefer the oil form, where the bark’s dryness is carried in a nourishing base. As with any preparation meant for the skin, a small patch test is a sensible first trial, and anyone with a persistent skin concern should speak with a qualified practitioner.
