Patra-Piṇḍa-Sveda, Kerala Specialty Form
A Kerala form of leaf-bolus fomentation. The record describes boluses of nirguṇḍī, eraṇḍa, citrus and tāmra cooked in oil, then applied warm in rhythmic strokes. It is a supervised clinic treatment. The record gives no temperature, no session length and no course length, so ask the clinic directly.
Given by a trained therapist. This is done to you by someone trained, normally in a clinic. It is described here so you know what a session involves and what to ask before booking, not as instructions to follow.
What it is
This is the Kerala specialty version of patra-piṇḍa sveda, leaf-bolus fomentation. Warm boluses made of herbal leaves are applied to the body rather than steam or a liquid stream. The record files it as an external procedure (kriyā-bāhya) in the piṇḍa subcategory and glosses it as “herbal-leaf bolus svedana (Kerala specialty)”.
The site also carries a record for the base form of patra-piṇḍa sveda. The two are close. What separates this entry is the addition of tāmra to the bolus contents and the explicit second step of warm rhythmic application.
Where it sits in the classical literature
The record cites Sahasrayogam. Sahasrayogam is a Kerala compendium of roughly a thousand formulations organised by preparation type, kaṣāya, ghṛta, taila, cūrṇa, ariṣṭa, āsava, lehya and a pariśiṣṭa appendix. It is a formulary, not a procedure manual, and no public source we checked shows it describing this procedure, so the citation is unverified.
The class the procedure belongs to is on firmer ground. Caraka Sūtrasthāna 14, the chapter on sudation, defines saṅkara sveda at verse 41 as local sudation “carried out with the lumps prepared of articles mentioned above, either wrapped in a cloth or unwrapped”. Bolus fomentation as a category is classical; this particular Kerala recipe is not traced to a text here.
What it involves
Two steps are recorded. Boluses of nirguṇḍī, eraṇḍa, citrus and tāmra are cooked in oil. They are then applied warm, in rhythmic strokes.
Nothing else is recorded: no preparation, no aftercare, no session length, no number of days, no frequency, no season.
What is used
Four bolus contents are named: nirguṇḍī, eraṇḍa, citrus, and tāmra, which is the Sanskrit word for copper. The record does not say in what form the tāmra is included or why, and does not gloss the term, so nothing further should be read into it here.
The boluses are cooked in oil, but the record leaves the oil unnamed. Its dedicated oil and dravya fields are both empty, so all four ingredients come from the wording of the procedure step.
What to ask before booking
The record is thin on everything a person books around. There is no bolus temperature, no session length, no course length, no frequency, no season, no contraindication and no adverse event in it.
Useful questions for the clinic: which oil the boluses are cooked in, whether tāmra is used and in what form, how hot the boluses are and how that is checked against your skin, how long a session runs, and how many sessions are being proposed.
Cautions
- The boluses are applied warm and the record gives no temperature. Ask how the clinic checks bolus heat against skin before and during the session.
- The oil the boluses are cooked in is not named in the record. If you have a known sensitivity to a carrier oil or to citrus on skin, ask what is being used.
- Tāmra is copper. The record does not say in what form it is included, so ask directly if you have a known metal sensitivity.
- No contraindications and no adverse events are recorded. That is missing data, not a safety finding.
- No session length, course length, frequency or season is recorded, so any schedule quoted to you comes from the clinic, not from this source.
- The entire record is unverified, LLM-curated data and should be confirmed with a qualified practitioner.

Classical source
Sahasrayogam (as given in the record; not confirmed). Bolus fomentation as a class is defined at Caraka Sūtrasthāna 14.41 (saṅkara sveda). — not independently confirmed; treat the locus as approximate
The record cites Sahasrayogam, a Kerala compendium of about a thousand formulations organised by preparation type (kaṣāya, ghṛta, taila, cūrṇa, ariṣṭa, āsava, lehya, pariśiṣṭa prakaraṇa). It is a formulary rather than a procedure manual, and no public source consulted showed it describing patra-piṇḍa sveda. What is confirmable is the class: Caraka Sūtrasthāna 14.41 defines saṅkara sveda as fomentation with lumps, wrapped in cloth or unwrapped.
Common questions
- How does this differ from ordinary patra-piṇḍa sveda?
- In the records, very little. This entry is labelled the Kerala specialty form, adds tāmra to the bolus contents, and separates the warm rhythmic application into its own step. Both use nirguṇḍī, eraṇḍa and citrus cooked in oil.
- What is tāmra doing in a leaf bolus?
- Tāmra is the Sanskrit for copper. The record simply lists it among the bolus contents and gives no form, quantity or rationale, so the honest answer is that this source does not say.
- Which oil are the boluses cooked in?
- The record does not name one. Its oil field is empty and the procedure step says only 'cooked in oil', so this is a question for whoever is giving the treatment.
