Types of Lehyam in Ayurveda

In simple terms

Types of lehyam in Ayurveda are told apart not by their form, which they share, but by the herbs at their centre: some nourish and rebuild, some steady the mind, some support the breath.

Types of lehyam in Ayurveda all share one form, the sweet herbal jam, but differ by the herbs at their heart. Some, like Chyawanprash, are broad rebuilding tonics built on amla; some, built on the mind herbs, are medhya jams; others gather breath-supporting or nourishing herbs. The form is constant; the herbs give each its character.

What they all share

Before the differences, it is worth naming what every lehyam has in common, because it is a great deal. Each is a semi-solid herbal jam, an avaleha, made by the same classical method: a reduced decoction, a sweet base of jaggery or sugar, ghee, a herbal paste, and honey and fine spices folded in once cooled.

Each is taken the same way too, by the spoon, on a light stomach, as a course over weeks. So the types of lehyam are not different kinds of thing; they are one kind of preparation, directed to different ends by the herbs chosen for their centre. That is the key to the whole classification, and you can see the wider family in the guide to formulations.

The great rebuilding jams

The first and best known type is the broad rebuilding tonic, the rasayana jam meant to feed and steady the whole body over time. Chyawanprash is the model of this type, built on amla and a wide circle of strengthening herbs, and taken as a general nourishing course, especially through the cooler seasons.

These jams are not aimed at any one part of the body. Their whole design is broad: to build strength, or balya, and to nourish the deep reserve of vitality the texts call Ojas. When people picture a lehyam, it is usually this rebuilding type they have in mind, and it is the largest and most familiar group.

The mind jams

A second clear type is built on the medhya herbs, the group Ayurveda links with the mind, memory and clear thought. Brahmi stands first among them, with companions such as Shankhpushpi, and a jam built around them is a medhya lehyam.

Brahma Rasayanam is the well-known example, a jam whose whole shape points at the head: it is taken as a nourishing course to steady thought and support memory. These belong to the broader family of the medhya rasayana, and they are described in classical, supportive terms, the steadying of a scattered or tired mind, rather than as a remedy for any named condition. The herb Brahmi is the thread that runs through them.

The breath and nourishing jams

A third type gathers nourishing and breath-supporting herbs, and is reached for where the body is depleted or worn thin. Agastya Rasayanam, built around Haritaki with a strengthening base, is classically linked with the breath and the chest as well as with rebuilding strength. Vidaryadi Lehyam, built on the sweet, cooling Vidari tuber, is a nourishing jam for depletion and wasting.

These jams lean toward feeding a run-down body and steadying the dry, mobile quality the tradition calls Vata. They share the sweet, heavy, building nature of all lehyams, but their herbs turn that nature toward nourishment and the support of the breath in particular.

The classical texts name the actions these jams are built around in their own vocabulary. A nourishing, tissue-building action is brimhana; a strengthening one is balya; the general rebuilding and age-steadying work of the whole class is rasayana. A nourishing lehyam such as Vidaryadi Lehyam is described chiefly as brimhana and balya, which is simply the tradition’s precise way of saying it feeds and strengthens a depleted body. Reading these terms on a preparation tells you, at a glance, which corner of the lehyam family it belongs to and what the herbs at its centre are chosen to do.

How the herbs set the type

The pattern behind all of this is simple and worth holding onto. A lehyam is a vehicle, a sweet nourishing jam, and the herbs placed at its centre decide what it is for. Amla makes a broad rebuilding tonic; the medhya herbs make a mind jam; nourishing and breath herbs make a jam for depletion and the chest.

This is why the tradition classes lehyams chiefly by their central herbs and their intended action, or karma, rather than by their form. It is also why the right type for a given person is a matter for a qualified practitioner, who can match the herbs and the jam to the constitution and the aim.

Good to know

The types of lehyam in Ayurveda are best understood as one shared form directed to many ends: rebuilding tonics like Chyawanprash, mind jams like Brahma Rasayanam, and nourishing breath jams like Agastya Rasayanam and Vidaryadi Lehyam. The sweet jam is common to all; the herbs at the centre make each what it is.

Frequently asked questions

What are the main types of lehyam in Ayurveda?

Lehyams are usually grouped by the herbs at their centre and the direction of their action. There are the broad rebuilding tonics, such as Chyawanprash, built on amla; the mind jams, or medhya lehyams, built on herbs like Brahmi; and the nourishing and breath-supporting jams, such as Agastya Rasayanam and Vidaryadi Lehyam. The form is shared; the herbs set the type.

Is Chyawanprash the only kind of lehyam?

No. Chyawanprash is the most famous lehyam, but the class is wide. Brahma Rasayanam is a mind-supporting lehyam, Agastya Rasayanam and Vidaryadi Lehyam are nourishing and breath-supporting jams, and there are many others. Each is a lehyam in form, but each is directed by its own herbs to its own purpose.

What is a medhya lehyam?

A medhya lehyam is a herbal jam built on the medhya herbs, the group Ayurveda links with the mind and intellect, such as Brahmi and Shankhpushpi. Brahma Rasayanam is a well-known example. These jams are taken as a nourishing course to steady thought and support memory, in classical, supportive terms rather than as a remedy for any named condition.

How are types of lehyam classified?

The tradition classes them chiefly by their central herbs and their intended action, or karma: rasayana (rebuilding), medhya (for the mind), brimhana (nourishing) and so on. Some are also grouped by the channel or region they are directed to, such as the breath. The sweet jam form is common to all of them.

Which type of lehyam is best for me?

That depends on your constitution and your aim, which is why the choice belongs to a qualified practitioner rather than to a general rule. A broad rebuilding tonic, a mind jam and a nourishing breath jam are quite different in their herbs and their suitability. A practitioner matches the type to the person.
