Dravyaguṇa — Seven Dhātu Affinity
Dravyaguṇa — Seven Dhātu Affinity is a Hindu / Ayurveda - dravyaguna dhatu affinity body system as transmitted through the lineage Āyurvedic dravyaguṇa distinguishes a substance's rasa, guṇa, vīrya, vipāka, and prabhāva, while dhātu theory describes successive tissues nourished through digestion and metabolism. This diagram uses seven points from rasa through śukra as a teaching ladder, with each tissue represented by a target-organ proxy rather than a surface-anatomy claim.. This page lists every point in the system with sourced placements and links to cross-tradition correspondences curated for The Body Spiritual.

- Caraka Saṃhitā (P.V. Sharma (trans.), Caraka Saṃhitā, 4 vols., Chaukhamba Orientalia, 1981–1994) — Sūtrasthāna 1 and 26 establish the Ayurvedic categories of dravya, rasa, guṇa, vīrya, vipāka, and prabhāva; the dhātu nourishment sequence is discussed in the śarīra and cikitsā teaching passages.
- Vasant Lad, Ayurveda: The Science of Self-Healing (2nd ed., Lotus Press, 1984) — Modern teaching synthesis used to explain the seven-dhātu sequence and its customary organ-oriented teaching associations; it does not supply canonical normalized coordinates.
Known lineage variants
- The Saṃhitās describe dhātu formation, functions, and signs, but do not provide a front-view body diagram with measured points. All coordinates here are editorial target-organ proxies for substances or tissue concepts, not anatomical surface locations; uncertainty radii are therefore broad.
- Commentarial and modern teaching lists differ in whether rasa is treated as circulating nutrient fluid, plasma-like material, or the first dhātu, and in how majjā is glossed. This file retains the common seven-name sequence without claiming biomedical equivalence.
- Dhātu affinity is not the same as a herb's guṇa or doṣa action. The points mark the tissue or target-organ emphasis used in a pedagogical classification, not a claim that a substance physically travels to the plotted coordinate.
- Anatomical-right is rendered at x < 0.5 in the front view. The left/right placement of liver and kidney proxies follows that image convention, while the ladder's midline points are schematic.

Frequently asked
What is Rasa dhātu — nutritive fluid proxy?
Rasa dhātu is rendered as the first nourishment of the seven-tissue sequence, using the chest and heart region as a visual proxy for circulation and nourishment. This is a target-organ projection of a substance classification, not an anatomical map of plasma or a claim about a fixed rasa location.
What is Rakta dhātu — blood proxy?
Rakta dhātu is shown beside the upper-abdominal liver region because Ayurvedic teaching commonly uses the liver as a formative and target-organ reference for blood. The point is a target-organ projection of a substance/tissue category, not a claim that rakta is anatomically stored at this surface coordinate.
What is Māṃsa dhātu — muscle proxy?
Māṃsa dhātu is placed over the upper-limb field to make the structural flesh category visually legible in a front silhouette. This is a target-organ and tissue proxy for a substance classification, not a claim that the whole dhātu resides in one limb or at one skin point.
What is Meda dhātu — adipose proxy?
Meda dhātu is represented in the abdomen, a broad proxy for reserve, lubrication, and metabolic storage in modern Ayurvedic teaching. It maps a substance/tissue classification to a target-organ region rather than describing the anatomical distribution of adipose tissue.
What is Asthi dhātu — bone proxy?
Asthi dhātu is placed over a leg proxy so the dense skeletal category can be distinguished from the preceding soft tissues. The coordinate is a target-organ projection for a substance classification and must not be read as a surface diagnosis of bone.
What is Majjā dhātu — marrow and neural proxy?
Majjā dhātu is shown along the central axial line to accommodate the traditional marrow and inner-filling sense while acknowledging neural glosses in modern teaching. This is a target-organ projection of a substance classification, not a claim that one measurable tissue occupies the plotted midline.
What is Śukra dhātu — reproductive proxy?
Śukra dhātu is placed at the pelvic-floor proxy as the final generative category in this seven-step teaching ladder. The point represents target-organ affinity for a substance classification, not a claim that reproductive essence has a single anatomical surface location.
