20.27

prakṛtisthaṃ yadā vātaṃ pittaṃ vṛddhaṃ kaphakṣaye |

saṃruṇaddhi tadā dāhaḥ śūlaṃ cāsyopajāyate ||

kṛtakramasya sirāvyadhastato virekaḥ |

kṛtavirekasya vartmanī likhet |

sakṛllekhanādaśuddhau punarlekhayet jalaukobhiśca grāhayet ||

When increased pitta, kapha being decreased, obstructs vāta
that is in its normal state, then burning sensation and colic arise in him.

For one who has undergone the preparatory procedure, venesection, then purgation [should be performed].

For one who has undergone purgation, one should scrape the eyelids.

If uncleansed after scraping once, one should have it scraped again and have leeches applied.
