The Compendium of Caraka 7.10: daśamo 'adhyāyaḥ/

Now we shall explain the formulation of sudhā.

Thus said the reverend Ātreya:

Of all purgatives, sudhā is considered the sharpest; / for it swiftly breaks through the accumulation of doṣas, with violent perturbation.

Therefore, it should never be used in a mild bowel, / nor when the accumulation of doṣas is small, provided the channels are clear.

In anemia, abdominal disease, gulma, dermatosis, one afflicted with latent poison, / swelling, madhumeha, and when the mind is perturbed by doṣas—

knowing a patient gripped by such diseases to be strong, / one should administer mahāvṛkṣa; for when properly applied,

it immediately removes even a great accumulation of doṣas. / It is considered twofold: with few thorns and with many thorns.

The one with many thorns is superior to the one with few very sharp thorns; / by name it is snuk, guḍā, nandā, sudhā, and nistriṃśapatraka.

Having slit those two, the intelligent physician should extract the milky sap with a knife, / [from a plant] two or three years old, especially at the end of the dewy season.

Making it equal in amount to a decoction of bilva and the rest, or of bṛhatī, or of kaṇṭakārī individually, / he should dry it over coals.

Then he should drink a dose equal to a jujube fruit with saubīraka, / or with husk-water, or with juice of jujubes, or of āmalaka,

or with wine, curd scum, or citron juice; / sātalā, kāñcanakṣīrī, śyāmā and the rest, and the three pungents,

As available, he should impregnate them with the latex of sudhā for seven days; / then he should drink a jujube-sized dose with ghee or with meat broth.

The three pungents, triphalā, dantī, citraka, and trivṛt, / well impregnated with the latex of snuk, he should prepare as a jaggery drink.

Trivṛt, āragvadha, dantī, śaṅkhinī, and saptalā in equal parts, / he should put in cow urine for a night, then dry in the sun.

Having thus impregnated them for seven days, he should again impregnate them / for another seven days with the latex of snuk; then [perfumed powders] impregnated with that and dried,

or smelling a garland of fragrant flowers [so treated], or wrapping himself in a cloth [steeped in it], / kings with soft bowels purge easily and quickly.

Cooking an electuary with a decoction of śyāmā and trivṛt, / with latex of snuk, ghee, and molasses, he should have a person lick it in proper dose for purgation.

Or he should make him drink the latex of sudhā with vegetable broths, meat broths, or ghees; / or a person should eat dried fish or meat impregnated with it.

He should cook ghee with milk and āmalaka as in the case of caturaṅgula, / or prepare wine in milk, or cook ghee as before.

Here are two verses:

Seven with sauvīraka and the like, with ghee, and with broth, / the drink, smelling, electuary, and three formulations with vegetable broth and the rest;

two with dried fish and meat, one wine, and two ghees: / these twenty formulations of mahāvṛkṣa are proclaimed.

Thus ends the tenth chapter, titled "Formulation of Sudhā," in the Section on Formulation of the treatise composed by Agniveśa, redacted by Caraka, and, where unavailable, completed by Dṛḍhabala.
