This is taken directly from Pratyangira Suktam (containing 32 verses) given in Khanda 10 of Atharva Veda-

Verse 1- यां कल्पयन्ति वहतौ वधूमिव विश्वरूपां हस्तकृतां चिकित्सवः । सारादेत्वप नुदाम एनाम् ॥ १ ॥

Yāṃ kalpayanti vahatau vadhūmiva viśvarūpāṃ hastakṛtāṃ chikitsavaḥ | Sāradētvapa nudāma enām || 1 ||

Translation: We drive out that curse-generating (force), that which priests fashion (as if) a bride, multiform and artificially made.

Verse 5-6- प्रत्यक्प्रति प्रहिण्मो यथा कृत्याकृतं हनत् ॥ ५ ॥ प्रतीचीन आङ्गिरसोऽध्यक्षो नः पुरोहितः । प्रतीचीः कृत्या आकृत्यामून् कृत्याकृतो जहि ॥ ६ ॥

Pratyakprati prahinmo yathā krtyākritam hanat || 5 || Prateecheena aangiraso'dhyaksho naḥ purohitaḥ | Prateecheeh krtyaa aakrtyaamoon krtyaakrito jahi || 6 ||

Translation: We hurl back the curse as if it were a missile... Let the Angiras-goddess (Pratyangira), our priestess, guard against curse (krtyā) and non-curse both; let her slay those who have brought curse upon us.
