How Lehyams Are Made

How lehyams are made follows the classical avaleha method. A herbal decoction, the kashaya, is reduced; a sweet base of jaggery or sugar and a paste of herbs are cooked into it, with ghee, until the mixture thickens to a jam. Honey and delicate spice powders are folded in only once it has cooled.

One method for many jams

Ayurveda has one classical method for making a lehyam, and it holds whether the jam is a broad rebuilding tonic like Chyawanprash or one of the mind or breath preparations. The method is called avaleha, and it is set out in the old pharmacy texts as one of the recognised ways of preparing a medicine.

What changes between one lehyam and another is the herbs at the centre. What stays the same is the making: a decoction, a sweet base, a paste, ghee, a slow cooking to the right thickness, and a careful finishing. Understanding this one method is understanding how every lehyam is made. You can see the whole family in the guide to formulations.

The decoction and the paste

The making begins by drawing the strength of the herbs into two forms. First a decoction: the chosen herbs are simmered in water and the liquid is reduced down until it is dark and concentrated, carrying the herbal essence in a smaller volume.

Second a paste: a portion of the herbs, often the finer or more aromatic ones, is ground to a smooth paste, the kalka. Between them the decoction and the paste carry the qualities of the herbs into the jam, the decoction giving the water-soluble part and the paste and ghee giving the part that prefers fat.

The sweet base and the ghee

Into the reduced decoction the sweet base is cooked. This is most often jaggery or sugar, dissolved and cooked in until it melts into the liquid. The base is not merely for taste: it thickens the jam, preserves it, and is itself counted as a nourishing part of the medicine.

Ghee is added during the cooking as well, to carry the fat-soluble qualities of the herbs and to lend its own building character. The digestive fire, or Agni, is kept in mind throughout, which is why a little warming spice is usually part of the recipe, to keep so rich a preparation digestible. As the base and ghee cook in, the mixture begins to thicken toward a jam.

Cooking to the right thickness

The central stage is the slow cooking to the correct consistency. The mixture is cooked over a low, patient heat and stirred without pause, so that nothing catches on the vessel and the jam thickens evenly.

The cook judges the finishing point by classical signs rather than a clock: the colour darkens, the smell settles, and the mixture begins to hold its shape. In the old texts a well-cooked jam holds a thread or a shape between the fingers, and a cooled drop keeps its form rather than spreading. When these signs appear, the cooking is done and the vessel is taken off the heat.

The finishing powders and honey

The last step is the finishing, and it is done off the heat. Once the jam has cooled, the most delicate aromatic powders, the prakshepa dravya, such as cardamom, cinnamon or the fine pepper, are folded in, along with the honey.

Honey is added only at this cool stage, never during the hot cooking, because the classical view holds that honey should not be strongly heated. This finishing both aromatises the jam and adds a light, carrying, often digestive quality that balances the heaviness of the sweet base. It is the touch that gives a well-made lehyam its fresh depth of flavour above the richness beneath.

Keeping quality

A well-made lehyam keeps well, and this is by design. The high proportion of sugar or jaggery, together with the ghee, acts as a natural preservative, so a good jam remains sound for many months when it is stored in a clean, dry, sealed vessel and taken with a clean, dry spoon.

Any sign of fermentation, souring or mould means the jam has spoiled and should be discarded. This keeping quality is part of why the form suits a rasayana, a preparation meant to be taken a little at a time over a long course.

Good to know

The making of every lehyam is the avaleha method in full: a reduced decoction, a sweet base and ghee, a herbal paste, a slow cooking to a holding thickness, and the honey and fine powders folded in only once cooled. The herbs at the centre change; the patient method does not.
