‘Ūha’ is inference or conjecture. ‘Nir’ is an Upasarga giving the meaning ‘without’ or ‘free from’ to the word to which it is prefixed.

स दोषनिर्हरणाच्छरीरनीरोहणाद्वा निरूहः|| (Su.Chi.35/18)

The procedure which causes the removal of aggravated Doṣa from the body and procedure in which Dravya moved in upward direction in the body is known as Nirūha.

वयःस्थापनादायुःस्थापनाद्वा आस्थापनम् | (Su.Chi.35/18)

Nirūha Basti is also termed as Āsthāpana Basti, which means it maintains youthfulness and increases the life span.

तद्वयःस्थापनाद्दोषस्थापनाद्वास्थापनमित्युच्यते शरीरारोहणाद्दोषनिर्हरणादचिन्त्यप्रभावतया यस्मिन्नूहासम्भवान्निरूह इति॥ (A.Sa.Su.28/7)

Nirūha Basti is known as Āsthāpana because this procedure makes the age static. It is called Nirūha because it moves upward in the body, expels the Doṣās out, because it is not possible to conjecture its effects due to its inconceivable efficacy.

SYNONYMS

आस्थापनं, निरूह इत्यनर्थान्तरं;  (Su.chi.35/18)

Nirūha Basti , Āsthāpana Basti, Kaṣāya Basti are its synonyms.

By considering the different stages of diseases, we can administer Basti in conditions such as,

बद्धोदरादावाध्मातानां बस्तिर्निषिध्यते; तेन “स्निग्धाय बद्धोदरिणे” इत्यादिना यावच्च “निरूहं सानुवासनम्” (चि.अ.१३) इति ग्रन्थेन निरूहविधानमविरुद्धं भवति; अन्ये तु उदराध्याय एव ‘बद्धोदरिणे’ इत्यनेन सविबन्धोदरिविषयं निरूहं वर्णयन्ति, तेनात्र सामान्येन बद्धोदरे निरूहनिषेधो न विरुद्धः| | (Chakrapani १४–१५) ||

In Alpāgni or Mandāgni, where there is less aggravation of Kapha, then Kaphaghna Nirūha Basti can be administered.

In Baddhodara; if the condition is associated with Vibandha, then Nirūha Basti can be administered.

If Hikka occurs due to administration of excessive Tīkṣṇa Basti to a Durbala person, having Mṛdu Koṣṭha, in this condition, Vāta is aggravated. So Anuvāsana Basti can be administered.
