Medical Astrology Framework
1. Signs (Rāśis / Zodiac Signs) → Outward Manifestation
Western View:
Each sign governs a body region (Aries = head, Taurus =
throat, Gemini = lungs/arms, etc.).
Signs show external symptoms and visible
tendencies—skin eruptions, posture, facial features, or outwardly
observable conditions.
Example: Leo rules the heart and spine → outward issues like
palpitations, spinal curvature, or visible vitality loss.
Vedic View:
Rāśis act as the field where disease manifests. They
show the external locus of imbalance.
Fire signs (Agni tattva) → fevers, inflammations.
Water signs (Jala tattva) → phlegm, oedema, excess fluids.
Earth signs (Pṛthvī tattva) → structural, bone, tissue
disorders.
Air signs (Vāyu tattva) → nervous disorders, tremors,
circulation issues.
2. Bhavas (Houses) → Inward Disease / Root Cause
Western View:
Houses contextualise disease in terms of life areas and
psychological roots.
6th house = illness, habits, diet.
8th house = chronic disease, genetic inheritance.
12th house = hospitalisation, hidden suffering.
Houses reveal the inner environment—stress, lifestyle,
karmic predisposition—that fosters disease.
Vedic View:
Bhavas are the inner seat of disease, showing how
imbalance penetrates deeper layers of being.
6th bhava (Roga sthāna) → direct diseases, enemies of
health.
8th bhava → longevity, incurable or hidden diseases.
12th bhava → loss of vitality, sleep disorders,
hospitalisation.
3rd bhava → vitality of courage, nervous strength.
1st bhava (Lagna) → overall constitution; if afflicted, the
whole system suffers.
3. Planets (Grahas) → Specific Nature of Disease
Western View:
Planets are the agents of disease, showing type and
quality.
Mars → fevers, accidents, inflammations.
Saturn → chronic, degenerative, cold diseases.
Moon → fluids, hormonal imbalance, psychosomatic conditions.
Mercury → nervous disorders, speech impediments.
Vedic View:
Grahas are the karakas (causal indicators) of
disease.
Sun → vitality, fevers, eye disorders.
Moon → mind, fluids, blood pressure.
Mars → bile, blood, accidents.
Mercury → skin, nerves, speech.
Jupiter → liver, obesity, diabetes.
Venus → reproductive organs, kidneys, venereal disease.
Saturn → bones, paralysis, chronicity.
Rāhu/Ketu → mysterious, karmic, psychosomatic, or epidemic
diseases.

Refined Synthesis
Signs = Where disease shows outwardly (body
part, external manifestation).
Bhavas = Why disease arises inwardly (karmic,
psychological, lifestyle roots).
Planets = What disease is specifically (nature,
organ, pathology).
Thus, medical astrology becomes a triadic diagnostic
system:
Signs = Stage
Bhavas = Depth
Planets = Actors
