Hold one of these and it barely weighs anything at all. A camphor tablet, white and faintly waxy, about the size of a sugar cube, sits without complaint on the small steel plate kept ready for the evening aarti flame. Lit, it burns down within the hour, unhurried, leaving no residue behind. Not swept away, not thrown out. Gone, the way a held breath is gone. This is the small, ordinary story of that tablet: what it is made of, where it grows, how it reaches an Indian shelf, and the three unremarkable jobs one piece of it can still do in a single day.
Grown Where the Air Is Thick With It
Camphor begins as a tree, Cinnamomum camphora, native to Taiwan, southern Japan, southern China and northern Vietnam. It is a white substance, packed in fine crystals through the wood, the bark and the leaves, and for most of its history it was drawn out by chipping the timber into small pieces and steam-distilling it, the vapour cooled until pale crystals form. There is no chemistry set involved in the traditional method, only heat, water and patience, the same three ingredients behind a great deal of what ends up on a puja tray.
In many puja trays, including my own, a small tin of camphor tablets sits within easy reach of the diya and the incense. It is one of the few objects on that tray whose origin runs, if you follow it back far enough, to a single named species of tree growing on the far side of Asia, rather than to a vague and undated "tradition" with no address at all.
From Taiwan's Forests to an Indian Shelf
Most of the camphor sold today, including most of what reaches an Indian shop, is not distilled from a tree at all. It is synthetic, made from turpentine oil, and tree-derived camphor is now the smaller share of the market rather than the whole of it. Before the First World War, most of the world's traded camphor came out of natural forests in Taiwan, and camphor stayed a major Taiwanese industry right through the Japanese colonial period, from 1895 to 1945: a documented trade with names, dates and shipping routes attached to it, not a vague "ancient ritual" with no address. India tried more than once to close that gap by growing the tree itself; colonial-era records point to attempts, reportedly beginning in the 1880s, at Lucknow's Horticultural Gardens to establish camphor-yielding stands on Indian soil, though the surviving accounts of those trials are thin. Whatever the exact scale, the yields never matched Taiwan or Japan, and the country's supply settled instead into an industry built largely on chemistry rather than forestry. What began as forest, then became factory output, then became a tablet on a shelf: one bought in a market stall in Mysore or a small shop in a Bengaluru side street sits at the end of that same long, narrowing chain. Neither version is a lesser object for it. Natural or synthetic, both still do the one thing that makes camphor useful on an altar: turn from a solid straight into air, with nothing left behind.
Not everyone treats that distinction as unimportant, though. Some who buy camphor specifically for the flame still ask for the tree-derived kind, holding that it burns differently or carries something the synthetic version does not. That is a belief no shopkeeper's chemistry can settle either way, and the two versions are rarely labelled apart on a market shelf, so most buyers end up choosing on scent and price rather than on provenance at all.
Burned Without Ash
Camphor does something unusual among common solids. When it burns, it turns straight from a solid into a vapour, without ever becoming a liquid along the way. That is the plain reason a lit tablet leaves the plate almost exactly as it found it, aside from a faint, dry mark. No wax pool, no charred stub, no ash to tip out afterwards. In an aarti, kapoor is lit on a small plate or spoon and carried in slow circles before the image on the altar, the flame moving where a hand moves it. It is a small, deliberate act, not a passive one; the person lights it, holds it, decides how long the offering lasts. A thread of incense smoke often rises in the same room while this happens, though the smoke does not do the work the person is there to do; that part stays with the hand holding the plate.
Three Calm Ways to Live With One Tablet
The first use is the one most households know: lit at dusk, held on its plate, offered in the aarti flame, gone within minutes, turned to air the way it always does. The second is less ceremonial and just as common in many homes: a tablet dissolved into a bucket of mopping water, the sharp, clean scent of camphor left behind on the floor long after the water has dried, valued for that scent as much as for anything else. The third is quieter still, a tablet simply tucked into a cupboard corner, where its smell has long been used as a household deterrent against moths and the damp that settles into stored cloth during a monsoon.
Three uses, one small object, none of them requiring belief in anything beyond what is plainly true: lit, it disappears cleanly, leaving no residue behind; dissolved, its scent lingers in water; tucked away, its smell keeps moths at bay in a folded shawl. Whether it also clears a room of something less visible is a question every household answers for itself, and the tablet asks nothing of the reader either way. It only does what it does, reliably, and then it is gone.
A word of caution worth keeping: the camphor sold as "pachha karpooram" for cooking is a separate, food-grade product, labelled and sold apart from the type meant for the flame, and the two should never be swapped for each other. Ritual camphor is for burning, not eating. In a home where the evenings are marked this way, other small habits often sit alongside it, each belonging to its own tradition, each answered to on its own terms. None of them need to agree with each other. A house can hold more than one quiet habit at a time, each one simply doing its own small, honest work.
