# Kaṭi Basti (Localized Lumbar Oil Pool)

> Kaṭi Basti is an external procedure for the lower back. A ring of black-gram-flour dough is placed on the lumbar region, warm medicated oil is pooled inside it and periodically renewed, and the whole thing runs about thirty to forty-five minutes. It is given by a trained therapist.

## Key facts

- **Sanskrit name:** कटि बस्ति / Kaṭi Basti

## What it is

The record classes Kaṭi Basti as *kriyā-bāhya*, an external procedure, subcategory *kaṭi* (the lumbar region), and glosses it in English as a localized lumbar oil pool. Like [Jānu Basti](/nighantu/practice/janu-basti/), it uses the word *basti* in the sense of a retained pool rather than an enema; nothing is introduced into the body.

## What it involves

The record gives two steps:

1. A dough ring made of black-gram flour is placed on the lumbar region, and warm *taila* is pooled inside it and retained.
2. The oil is periodically renewed, for a total of 30 to 45 minutes.

That renewal step is the practical difference from the knee version in the same dataset: the oil is replaced during the session rather than simply left. The record gives no preparation, no aftercare, no course length, no frequency and no seasonal guidance.

A search-result summary of a 2008 clinical study in *AYU* describes the same procedure with the person lying prone and a period of 40 to 45 minutes. I was not able to read that paper in full, so treat the prone positioning and the slightly different timing as an indication of how the procedure is done in practice rather than as a checked figure.

## What is used

- **Black-gram flour**, made into the dough ring that walls the oil in
- **Mahānārāyaṇa Taila**
- **Sahacarādi Taila**

The record names no instruments and no other dravyas, and does not say which of the two oils suits which presentation.

## Where the citation stands

The record cites *Sahasrayogam (regional Kerala)*. The Kerala part is well supported: Kaṭi Basti is generally placed as a technique of the Keraliya tradition rather than one of the procedures set out in the foundational saṃhitās. The *Sahasrayogam* part I could not confirm. Sahasrayogam is structured as a formulary, cataloguing on the order of a thousand or more formulations alphabetically along with sections on *nidāna*, *guṇapāṭha* and *śālākya-tantra*, and I found no confirmation that it contains a description of this procedure as opposed to oils used in it.

## What to ask before booking

- which of the two oils, and why that one
- how the oil temperature is set and checked, since the pool sits on skin for the better part of an hour and is topped up warm
- whether the back has been assessed first, and by whom
- how many sessions are proposed, since the record gives no course length at all
