The Compendium of Kāśyapa 1.26: ṣaḍviṃśatitamo'dhyāyaḥ

Now we shall explain the chapter on the Excellence of Treatment.

Thus spoke the venerable Kaśyapa.

We shall explain the means by which excellence of treatment is achieved. Indeed, there are four / pillars of treatment. When they are endowed with virtues, a curable / disease does not exceed control. Namely: the physician, the medicament, the patient, and the attendant.

Among them, the physician should be of good lineage of instruction, properly endowed with the knowledge of the seers, learned, experienced through repeatedly observed practice,
knowledgeable in proven formulations, competent, courteous, pure, modest in dress, friendly toward all beings,

successful, regarding duty and welfare, devoted to truth, compassion, charity, and rectitude, a worshipper and visitor of gods, twice-born, elders, and accomplished masters, skilled in successive steps of diagnosis and therapy, attentive to preceptors and elders, committed to right reason, devoid of fear, greed, delusion, anger, falsehood, slander, and craving for intoxicating drinks, pleasant-faced, and free from addictions.

Here, excellence of the medicament: grown in good soil, collected at the proper time, produced in the proper season, unaltered, undamaged by fire, water, insects, faeces, urine, aging, and the like, suitable for the specific disease, and prepared methodically in due order.

There, the excellence of the patient: curability of the disease; firmness of mental stamina, strength, intellect, body, sense faculties, resolve, and vitality; accurate reporting of the etiology, prodromal symptoms, disease, complications, prognosis, wholesome adaptations, and unwholesome adaptations, or [such reporting] by the wet-nurse; faith; revering gods, twice-born, preceptors, physicians, medicaments, and friends; orthodoxy; predominance of humility; compliance with instructions; and self-control.

There, the excellence of the attendant: mature emotions, health, capability, devotion to the master,
knowledge of nursing, dexterity, cleanliness, quickness of action, skill in all procedures,

freedom from disgust, not having vile offspring, lack of duplicity, self-restraint, conquering anger and similar faults, and endurance.

Here are verses on this:
Some consider the patient the foremost of this tetrad of limbs,
for it is for his sake that the three qualified limbs are desired here.

Prajāpati said, “Not so! Treatment has the physician as its root.
For the trivarga is subject to the physician, and success resides in the physician.

He combines, administers, and directs through the eye of knowledge;
therefore, the physician accomplished in theoretical knowledge and practical comprehension is the most excellent.

When the excellence of the four limbs is present, O Jīvaka,
then the physician becomes a vessel for virtue, wealth, and renown.”

Thus spoke the venerable Kaśyapa.
Thus ends the twenty-sixth chapter, entitled “The Excellence of Treatment.”
