The text links this trouble to a priest who bathes but does not offer homa, or who eats without making an offering.
The English below is our translation from the Sanskrit.
Hikka (hiccups) - past deeds
यः पुनः स्नात्वाअजुहुयादहुत्वा वा ब्राह्मणोभुंक्ते स हिक्कारोगी भवेत् । स त्रीणि चांद्रायणानि सातिकृच्छ्राणि चरेत् । ता मग्निवर्णामित्यादिसूक्तं जपेत् ससुवर्णमन्नदानं च ॥
A brahmana (priest) who bathes but does not offer homa (fire offering) may suffer from hiccups. So may one who eats without offering it. He should keep three chandrayana (moon-phase fast) fasts, each with an atikrichchhra (a harder penance fast). He should do japa (repeating a mantra) of the sukta (Vedic hymn) that begins "tam agnivarnam". He should also give a gift of food with gold.
Unit 22.1 names three chandrayana fasts, japa of a hymn and a gift of food with gold.
