What it is
Gandharvahastadi Kashayam is a kashayam, which is a herbal decoction. A decoction is made simply: a set of herbs is boiled in water for a long time and reduced down, until the water carries the strength of the herbs. The solids are then strained away and the dark, bitter liquid that remains is the medicine.
The name points to its lead herb. Gandharvahasta is one of the old Sanskrit names for the castor plant, and adi means “and the others.” So the name reads as the decoction of the castor root and the herbs that go with it. The castor root sets the character of the whole formula, and the supporting herbs round it out.
What it is used for
This is a Vata decoction. In Ayurveda, Vata is the dry, cold, mobile quality that governs movement, and when it rises too high and settles in the lower body it shows as stiffness, aching and heaviness in the back, the hips and the legs.
Gandharvahastadi Kashayam is the decoction the tradition reaches for in exactly that picture. The castor root has two jobs the texts value here. It settles Vata, and it gently guides it downward and onward, the action the texts call anulomana, so that what has gathered and grown stiff begins to move again. The supporting herbs strengthen and steady the body around that action. The whole formula is warming and softening, meeting the cold, dry, stuck quality of an aggravated Vata.
How it is made
The castor root sits at the heart of the formula, and around it stand a number of supporting herbs. Several of them are strengthening roots that the tradition uses to settle Vata and build the tissues, among them Bala and Ashwagandha, along with a little long pepper root and warming Devadaru to keep the digestion bright.
These herbs are dried and broken into a coarse powder. The powder is soaked, then boiled in plenty of water, the classical measure being one part herb to sixteen parts water. The pot is kept at a steady, gentle simmer, never a fierce boil, and the liquid is reduced down to about a quarter of what it started as. At that point the decoction has darkened and thickened a little, and it is strained clear through cloth. A kashayam is made fresh and used fresh; it does not keep for long.
How it is taken
A kashayam is taken by mouth. The classical dose is a small measured cup, often diluted with an equal part of warm water, taken once or twice a day. It is usually taken before food, on a fairly empty stomach, so it is well absorbed.
The anupana, the helper it is taken with, is chosen to suit the person. For settling Vata the tradition often pairs it with a little warm sesame oil or warm water. As with all the decoctions, the right dose and pairing are matters for a practitioner to judge.
Good to know
This entry sets out the classical Ayurvedic understanding of the decoction. It is a traditional preparation, not medical advice, and anyone with a health condition should speak to a qualified practitioner. A kashayam is bitter by nature, and that bitterness is part of how it works.
Frequently asked
Why is it named after the castor plant? Because Gandharvahasta is an old Sanskrit name for the castor plant, and the castor root is the lead herb of the formula. The name marks out the herb that gives the decoction its character.
Is it the same as a churnam or an arishtam? No. A churnam is a dry powder and an arishtam is a fermented tonic. A kashayam is a fresh water decoction, herbs boiled down in water and strained, with no fermentation and no powder to swallow.
When is it taken? Usually before food, once or twice a day, in a small measured dose mixed with a little warm water. A practitioner sets the exact amount and the helper it is taken with.
Where the wind has gathered below and the limbs grow stiff, the decoction of the castor root is given to set it moving.

Frequently asked questions
What is Gandharvahastadi Kashayam used for?
Gandharvahastadi Kashayam is a classical herbal decoction built around the castor root, traditionally taken to settle Vata and ease stiffness and heaviness in the lower body. Its karma is described as vatahara and anulomana, settling Vata and guiding it downward, so Ayurveda associates it with sluggish elimination and the stiff, heavy quality of aggravated Vata.
What is Eranda in Gandharvahastadi Kashayam?
Eranda is castor, and its root (Gandharvahasta) is the lead ingredient that gives the kashayam its name and character. Ayurveda prizes castor root as a foremost Vata-settling and downward-guiding herb (vatahara, anulomana), which is why this decoction is turned to for stiffness, heaviness and sluggish movement in the lower body.
How do you take Gandharvahastadi Kashayam?
Gandharvahastadi Kashayam is a decoction, usually taken diluted with warm water before food, once or twice a day, sometimes with a specified anupana. Because it is a potent classical preparation that works on Vata and elimination, the dose and course are best set by a qualified Ayurvedic practitioner rather than chosen on your own.
Which dosha does Gandharvahastadi Kashayam balance?
Gandharvahastadi Kashayam is a Vata preparation. Its bitter, astringent and lightly sweet taste (tikta, kashaya, madhura) supports its vatahara and anulomana action, settling Vata and guiding it downward. It is chosen for the stiffness, heaviness and sluggish movement of aggravated Vata in the lower body rather than for heat or Kapha-led conditions.
Is Gandharvahastadi Kashayam good for constipation and stiffness?
Ayurveda uses Gandharvahastadi Kashayam to guide Vata downward (anulomana) and to ease the stiffness and heaviness that aggravated Vata brings to the lower body, which is the classical logic behind these applications. It is a traditional framing rather than a modern treatment. Persistent constipation or stiffness should be reviewed with a qualified practitioner and your doctor.
