Planetary Rulerships: Mars (Inflammation), Saturn (Chronic), etc.
Share
BY NICOLE LAU
Each planet governs specific physiological functions and health patterns. Mars brings inflammation and fever. Saturn creates chronic conditions and restrictions. Jupiter expands (for better or worse). Neptune dissolves boundaries and creates sensitivity.
Understanding planetary rulerships is essential for medical astrology. Your Mars placement shows where inflammation occurs. Your Saturn shows where chronic issues develop. Your Neptune reveals sensitivities. Your Pluto indicates transformation and regeneration.
This is your complete guide to planetary health rulerships.
What you'll learn: The Sun and Moon (vitality and rhythms), Mercury (nervous system), Venus (hormones and balance), Mars (inflammation and energy), Jupiter (expansion and excess), Saturn (chronic and structural), Uranus (sudden and electrical), Neptune (sensitivity and dissolution), Pluto (transformation and elimination), and how to read planetary placements for health insights.

Reading Planetary Placements for Health
Step 1: Identify Planetary Positions
Note: Sign (constitutional type), House (where health manifests), Aspects (how planets interact).
Step 2: Look for Patterns
Stelliums: Multiple planets in one sign/house = concentrated health focus. T-Squares: Tension between planets = health challenges requiring integration. Grand Trines: Easy flow = natural health strengths. Oppositions: Polarities requiring balance.
Step 3: Note Challenging Aspects
Hard aspects (square, opposition, conjunction with malefics): Show health challenges and areas requiring attention. Not fate, but tendencies requiring awareness and prevention.
Step 4: Identify Strengths
Soft aspects (trine, sextile, conjunction with benefics): Show natural health strengths and healing capacities. Resources to draw upon.
Step 5: Consider Transits
Current planetary movements: Activate natal placements, bring health themes to surface, timing for health interventions or challenges.
Practical Application Examples
Example 1: Mars in 6th House Square Saturn
Mars in 6th: Active health approach, inflammation-prone, needs exercise. Square Saturn: Frustrated energy, chronic inflammation, discipline required.
Health Pattern: Chronic inflammation from frustrated energy. Wants to be active but feels restricted. May have chronic pain or joint issues affecting activity.
Healing Approach: Disciplined exercise routine (Saturn), anti-inflammatory diet, anger management, patience with body, structured physical therapy.
Example 2: Neptune in 12th House Opposite Moon in 6th
Neptune in 12th: Hidden sensitivity, psychosomatic illness, boundary issues. Moon in 6th: Emotional health connection, digestive sensitivity. Opposition: Tension between conscious (6th) and unconscious (12th) health.
Health Pattern: Digestive issues from unconscious emotional patterns. Absorbs others' stress. Psychosomatic stomach problems. Unclear symptoms.
Healing Approach: Emotional therapy, boundary work, spiritual practices, gut healing, immune support, conscious emotional processing.
Example 3: Jupiter in 2nd House Trine Venus in 6th
Jupiter in 2nd: Abundant resources, may overindulge, liver focus. Venus in 6th: Pleasure in wellness, balanced approach, aesthetic self-care. Trine: Easy flow between abundance and wellness.
Health Pattern: Enjoys healthy pleasures, abundant self-care, may overindulge but recovers well. Good liver function if moderation practiced.
Healing Approach: Enjoy wellness (Venus), practice moderation (balance Jupiter), aesthetic healthy pleasures, liver support, mindful indulgence.
