Understanding the Planets, Houses, and Remedies for Health
1. What Is Medical Astrology?
Medical astrology - known as Arogya Jyothisham in ancient Tamil texts - is the branch of astrology that studies the connection between planetary energies (grahas) and the physical body (deham).
Every rasi, bhava, and nakshatra governs certain organs and physiological functions. When afflicted, these celestial points reveal potential weaknesses or diseases.
The Sithars of Tamil Nadu described the human body as a miniature universe - the Pancha Bhoothas (five elements) expressing through planets and their vibrations. Thus, disease is seen not merely as a biological event but as a karmic imbalance manifesting through planetary influence.
Medical astrology helps us understand:
-
Why certain ailments appear repeatedly in a family line.
-
When diseases manifest, based on dasha and transit.
-
How we can harmonize energy through remedies and awareness.
2. The Astrological Foundations of Health and Disease
2.1 The Houses of Health
In Vedic astrology, three key houses (bhavas) form the health triangle:
-
6th House - Roga Bhava: Represents disease, immunity, and service. Afflictions here bring frequent illness or stress-related disorders.
-
8th House - Ayu Bhava: Indicates longevity, hidden diseases, and chronic issues. Malefic influence causes prolonged suffering or genetic ailments.
-
12th House - Vyaya Bhava: Denotes hospitalization, loss of vitality, or expenditure on health.
The interconnection between these three houses determines whether an ailment is temporary, recurrent, or chronic.
2.2 The Key Grahas (Planets) and Their Influence
| Graha | Health Domain | Diseases when Afflicted |
|---|---|---|
| Sun (Surya) | Vitality, heart, bones | Eye defects, heart issues, fever, bone weakness |
| Moon (Chandra) | Mind, fluids, emotions | Depression, anxiety, glandular and hormonal disorders |
| Mars (Sevvai) | Blood, muscles, energy | Accidents, bleeding, inflammation, ulcers |
| Mercury (Budhan) | Nerves, skin, lungs | Speech issues, nervous disorders, skin rashes |
| Jupiter (Guru) | Liver, hormones, growth | Diabetes, obesity, liver disease |
| Venus (Sukra) | Reproduction, kidneys | Fertility problems, kidney stones, skin allergies |
| Saturn (Sani) | Bones, chronic illness | Arthritis, paralysis, aging diseases |
| Rahu | Unknown, toxic energies | Cancer, addiction, mysterious illnesses |
| Ketu | Immunity, detachment | Autoimmune disorders, sudden collapse |
Every chart must be read holistically - affliction, aspect (drishti), and planetary strength (bala) define the actual health pattern.
2.3 The Significance of Lagna and Moon
-
The Lagna (Ascendant) represents the physical body and constitution.
A weak or afflicted lagna lord often signals poor health endurance. -
The Moon governs fluids, mind, and emotional stability; its position and aspects influence psychosomatic illnesses.
3. Rasi, Nakshatra, and Body Mapping
Our ancient texts (especially Sarvartha Chintamani and Brihat Parashara Hora Shastra) describe the body as divided among 12 rasi:
| Rasi | Body Part Governed |
|---|---|
| Mesham (Aries) | Head & brain |
| Rishabam (Taurus) | Face, throat |
| Mithunam (Gemini) | Arms, lungs |
| Kadagam (Cancer) | Chest, stomach |
| Simmam (Leo) | Heart, spine |
| Kanni (Virgo) | Intestines, digestion |
| Thulam (Libra) | Kidneys, skin |
| Viruchigam (Scorpio) | Reproductive organs |
| Dhanusu (Sagittarius) | Thighs, liver |
| Makaram (Capricorn) | Knees, bones |
| Kumbam (Aquarius) | Ankles, circulation |
| Meenam (Pisces) | Feet, lymphatic system |
When malefic planets occupy or aspect these signs, related organs become vulnerable.
Similarly, nakshatras like Ashlesha, Moola, and Jyeshta are known for hidden karmic ailments, while Uttara Phalguni and Revathi promote healing.
4. The Disease Spectrum in Astrology
Here we begin the “hub” connection. Each sub-topic will link to an individual detailed article (like your cancer post). For now, we’ll place the first link.
4.1 Cancer and Tumor Formation
Among all diseases, Cancer represents uncontrolled cellular growth - astrologically linked to Rahu, Ketu, Moon, and Saturn.
Afflictions between Chandra (fluids) and Rahu (toxic expansion) are common.
Ailments manifest when the 6th, 8th, and 12th houses are connected through these planets.
