The Compendium of Caraka 7.5: pañcamo 'adhyāyaḥ/

Now we shall expound the procedure of vatsaka.

Thus declared the venerable Ātreya.

Now the names of vatsaka, and the distinction between female and male,
and its procedure, I shall declare in detail as it truly is.

Vatsaka, kuṭaja, śakra, vṛkṣaka, girimallikā;
its seeds are indrayava, and likewise called kaliṅgaka.

Having large fruits, white flowers, and unctuous leaves is the male;
and the female is darkish, with reddish flowers and small fruit stalks.

It destroys blood-pitta and kapha, causes no complications in delicate people,
and is commended in heart disease, fever, gout, erysipelas, and the like.

Having gathered the fruits of both at the proper time, one should store them dry.
Having crushed an antarnakhamuṣṭi of them, one should steep them

with a decoction of madhuka and likewise with kovidāra and the others;
having stood overnight, rubbed, and mixed with salt and honey,

one should drink that: an excellent emetic destroying pitta and kapha.
For eight days one should steep their powders with milk of arka;

then one should drink a pāṇitala with a decoction of jīvaka.
Likewise separately with [decoctions] of madana fruit, jīmūtaka, ikṣvāku, and jīvantī,

or with water of mustard seeds, madhūka, or salt,
or combined with spiced rice-and-lentil mash, the physician should administer emesis.

Here is a verse:

Nine with decoctions, five with powders, three with liquids are spoken of, / and one would be in spiced rice-and-lentil mash; those eighteen formulations are recorded.

Thus, in the treatise composed by Agniveśa, redacted by Caraka, and, being incomplete, completed by Dṛḍhabala, in the Section on Formulation, the fifth chapter, titled "The Formulation of Vatsaka." //5
