rūkṣaṇa: what the term means and how it is translated
rūkṣaṇa रूक्षण is an Ayurvedic technical term. It is rendered into English in 4 different ways, which is the reason this page exists: the renderings do not agree, and the difference between them changes what the term is taken to mean.

How it is translated, and whether the translation holds
Each rendering is given with the source that uses it. The assessment is ours.
rūkṣaṇaṁ (listed, untranslated, within 'Six types of treatment modalities')
WHO International Standard Terminologies on Ayurveda (2022) · ITA-9.1.42 ṣaḍvidhopakramāḥ: 'A subdividing of therapeutic measures into six categories: br̥ṁhaṇam, snehanam, stambhanam, laṁghanaṁ, svedanam and rūkṣaṇaṁ.' A stand-alone rūkṣaṇa entry was not found by grep; the index lists only rūkṣaṇa-apacāraḥ (ITA-5.76.9) and rūkṣaṇa-atiyogaḥ (ITA-5.76.10) and rūkṣaḥ (ITA-1.9.4.2.9) · comparator-standard
WHO 2022 appears to give no English head-term for rūkṣaṇa itself in section 9.1 (entries 9.1.43-46 cover bṛṁhaṇa, snehana, stambhana, laṅghana). Treat as a gap to confirm by reading the full section.

To cause dryness ; emaciation
NIA Jaipur / WHO-APW draft terminology (2011) · nia.nic.in/pdf/TERMINOLOGIES.pdf, entry rukṣaṇaṁ (code printed beneath: SK0164); companion entry rukṣa: 'Dryness; one of the 20 gurvādi guṇa...' · comparator-draft
Minimal gloss; 'emaciation' describes an effect, not the therapy.

Rukshana [untranslated]: 'That which brings about dryness, and roughness and paleness is said to be Rukshana.'
Kaviratna, Charaka Samhita, Sutrasthana Lesson XXII · archive.org OCR; his printed numbers 7-9 for the six definitions (standard Su. 22.9-11; rūkṣaṇa definition is Su. 22.10 per carakasamhitaonline) · public-domain-translation
'paleness' renders vaiśadya, which modern translators render 'non-sliminess/clarity'; Kaviratna's word is doubtful against the Sanskrit.
drying therapy / dehydrating therapy
Common textbook / web usage (easyayurveda, planetayurveda summaries surfaced in search) · textbook-usage · our paraphrase of the source, not its words
Widespread; 'dehydrating' is misleading (see mistranslations).
The classical passages
Each citation gives its address so a reader can check it in a printed edition, our account of what the passage establishes, and the result of reading it against its source.
Charaka SamhitaSutrasthana 22 (Laṅghanabṛṁhaṇīya):4 (carakasamhitaonline, Trikamji numbering); Kaviratna's number for this list is illegible in OCR ('**-*') · checked against the source
लङ्घनं बृंहणं काले रूक्षणं स्नेहनं तथा | स्वेदनं स्तम्भनं चैव
rūkṣaṇa is one of the six upakramas; verifies the Devanagari.
Charaka SamhitaSutrasthana 22:10 (carakasamhitaonline, Trikamji numbering). Kaviratna prints 7-9 after the block containing this definition. Both recorded; no arithmetic conversion. · checked against the source
br̥hattvaṁ yaccharīrasya janayēttacca br̥ṁhaṇam| raukṣyaṁ kharatvaṁ vaiśadyaṁ yat kuryāttaddhi rūkṣaṇam||10||
Definition: that which produces raukṣya (dryness), kharatva (roughness) and vaiśadya (clarity/non-sliminess) is rūkṣaṇa.
Charaka SamhitaSutrasthana Lesson XXII:Kaviratna's printed 7-9 (standard 9-11); and his 12 for the qualities (standard number not independently established, likely 22.14 but NOT verified) · checked against the source
That which brings about dryness, and roughness and paleness is said to be Rukshana. [...] Such things as are dry, productive of lightness, pungent, warm, stable, not slimy, and hard, are generally Rukshana.12
Kaviratna's English for the definition and for the properties of rūkṣaṇa substances.
Not to be confused with
- laṅghana
- Reducing/lightening therapy; a separate upakrama in Su. 22.4. Both reduce, but rūkṣaṇa is defined by dryness/roughness, laṅghana by lightness.
- snehana
- Its direct opposite among the six (Su. 22.11 defines snehana by sneha, viṣyanda, mārdava, kleda).
- rūkṣa (guṇa)
- The quality 'dry' (one of the gurvādi guṇas; NIA 2011 rukṣa entry); rūkṣaṇa is the procedure that produces it.
- udvartana
- Powder massage, a technique often performed as rūkṣa udvartana; a method, not the category.
- stambhana
- Arresting/astringent therapy; Kaviratna's property list for stambhana also includes 'dry', inviting confusion.
Renderings that do not hold
- dehydration therapy. Implies water loss; the Sanskrit targets sneha/kleda (unctuousness/moistness) and produces kharatva and vaiśadya, not fluid depletion.
- paleness (Kaviratna for vaiśadya). Doctrinally odd; vaiśadya is clarity/non-sliminess. Translator's word choice, not doctrine.
- fasting. Fasting (upavāsa) is a laṅghana method (Su. 22.18), not rūkṣaṇa.
Open questions
Recorded rather than resolved. Each one is something this entry cannot currently settle.
- Does WHO 2022 have a stand-alone rūkṣaṇa head-term anywhere (e.g. under 9.2 or 6.2)? grep on 'rūkṣaṇ' found only ITA-9.1.42, 5.76.9 and 5.76.10.
- Standard Trikamji number for Kaviratna's '12' (properties of rūkṣaṇa) not established.
- Peer-reviewed literature on rūkṣaṇa as a therapy: PubMed E-utilities 'rukshana' (39 hits) is polluted by an author surname; 'rukshana karma' and 'ruksha udvartana' returned 0. A 2023 Journal of Ayurveda (Wolters Kluwer) trial on ruksha udvartana in obesity appeared in web search but its DOI was not seen.
