vātena vātasadṛśāni ca lakṣaṇāni pittena dāhasarujavraṇaśoṣatāpāḥ
saṃśleṣmaṇā ca śītalaghanā samprayogātsyātsannipātavihitā ca samastaliṅgaiḥ

Just as fire whose fuel is burnt out [subsides], just as poison having destroyed the bodily tissues [ceases], / so fever, having accomplished its aim by destroying the body, attains peace.
