The Bṛhan-Nāradīya Purāṇa (quoted in Hari-bhakti-vilāsa 11.353) states:
acyutānanda-govinda-nāmoccāraṇa-bhīṣitāḥ
naśyanti sakalā rogāḥ satyaṁ satyaṁ vadāmy aham
I vow this is the truth. By hearing the names Achyuta, Ananda and Govinda one becomes strong and all diseases are cured.
Parāśara-saṁhitā (quoted in Hari-bhakti-vilāsa 11.354) says:
na śāmba vyādhi-jaṁ duḥkhaṁ heyaṁ nāny auṣadhair api
hari-nāmauṣadhaṁ pītvā vyādhis tyājyo na saṁśayaḥ
O Shamba! Diseases are not cured by other medicines, but by using this great medicine of hare kṛṣṇa they are definitely removed.
The Skanda Purāṇa (quoted in Hari-bhakti-vilāsa 11.355) states:
ādhayo vyādhayo yasya smaraṇān nāma-kīrtanāt
tadaiva vilayaṁ yānti tam anantaṁ namāmy aham
I offer my prostrated obeisance to that infinite Lord, because by remembering him, singing his names, all physical and mental ailments are forthwith rooted out.
The Vahni Purāṇa (quoted in Hari-bhakti-vilāsa 11.356) says:
mahā-vyādhi-samācchanno rāja-vādhopapīḍitaḥ
nārāyaṇeti saṅkīrtya nirātaṅko bhaven naraḥ
A person who is highly afflicted by acute and chronic diseases and oppressed by the ruling powers is relieved of all fears and anxieties by mere chanting of the name Sri Narayan.
