prakṛtisthaṃ kaphaṃ vṛddhaṃ pittaṃ vāyukṣaye yadā |

sannirundhyāttadā kuryāt satandrāgaurava jvaram ||

tuvarikāphalatrikarocanākvāthena madhumatā sāyaṃ prātaḥ sadā prakṣālanamañjanānte ca kaṣāyavṛkṣapallavakaṣāyeṇa ||

When, upon the decrease of vāta, increased pitta obstructs kapha that remains in its natural state, / it produces fever accompanied by drowsiness and heaviness.
Always, evening and morning, washing [the eyes] with a decoction of tuvarikā fruits, the three katu [trikatu], and rocanā combined with honey, and after applying collyrium, [washing] with an astringent decoction of leaves of astringent trees.
