Your birth chart, read as a map of your health.
Medical astrology is one of the oldest forms of personalised medicine. I read your natal chart as a constitutional blueprint, your humoral temperament, your strengths and vulnerabilities, then bring 27 years of clinical nursing to turn that insight into a practical plan for restoring balance.

What is medical astrology?
Medical astrology is the branch of astrology concerned with health and the body. For most of recorded history it was simply part of medicine: physicians from Hippocrates to Culpeper read the birth chart as a map of the constitution, a picture of how a particular body was built, where it ran hot or cold, dry or damp, and which systems were most likely to need support.
It works from the principle that each of us arrives with a constitutional temperament, a natural balance of the four humours, and that health is the art of keeping that balance. When the balance tips, the humours fall into what the tradition calls dyscrasia, and symptoms follow. The chart shows where that tipping is most likely for you, so it can be supported early.
It is observational and educational, never fortune-telling. It does not diagnose, predict or replace medical care. What it offers is a language for the patterns you may have always sensed in your own body but never been able to name, and a genuinely personalised starting point for supporting them.
A method, not a horoscope.
Every reading follows the same clinical-astrological sequence. This is traditional medical astrology worked properly, then brought together with integrative health so it becomes something you can actually use.
The charts I cast
Your natal chart in Whole Sign is the foundation, your lifelong constitution. Where a specific health question or episode calls for it, I also cast consultation, decumbiture and horary charts in Regiomontanus, the classical techniques for reading the moment of illness or the question itself. Together they give both the baseline and the present picture.
Temperament and the humours
I tally the elements and modes across your chart to establish your humoral temperament, the balance of choleric, sanguine, phlegmatic and melancholic. This is the heart of the work. It tells us your constitutional baseline and, when it tips into dyscrasia, exactly which direction it has tipped.
Body parts, houses and significators
I read the four health houses (the 1st, 6th, 8th and 12th), the signs and planets that fall in them, and the condition of your key significators, the Ascendant ruler, the Sun and the Moon. Each sign and planet governs particular body parts and systems, so this maps your constitutional strengths and the areas that ask for care.
The integrative plan
This is where the nursing comes in. The humoral picture guides real, practical choices: diet, herbs, supplements, movement and lifestyle chosen to gently correct the imbalance. Alongside the chart I use functional medicine testing, patterns of sensitivity, and clinical history, so the astrology and the evidence inform one another rather than working alone.
The foundation of the whole reading.
Your temperament is your constitutional baseline. Knowing it is what makes every recommendation, every food, herb and rhythm, specific to you rather than generic. This is where medical astrology and integrative health meet.
Driven and decisive, with strong digestive fire. Governs the liver, gallbladder, bile and muscles. Tips toward inflammation, heat and burnout.
Cool and moisten: bitter foods, calming herbs, rest.
Warm, sociable and well-circulated. Governs the blood, lymph, skin and breath. Tips toward congestion, excess and restlessness.
Cool and dry: structure, routine, less sugar.
Sensitive, deep and receptive. Governs the lungs, fluids, stomach and reproductive organs. Tips toward damp, heaviness and sluggish metabolism.
Warm and dry: movement, spice, fewer cold foods.
Steady, methodical and enduring. Governs the bones, joints, spleen and nervous system. Tips toward dryness, stiffness, constipation and worry.
Warm and moisten: healthy fats, hydration, connection.
Four houses tell the health story.
In traditional medical astrology, four houses in your chart carry the most about your health. I read each one, the sign on its cusp, any planets within, and where its ruler sits.
Vitality
The 1st house: your constitution, physical resilience and overall life force.
Daily Health
The 6th house: chronic patterns, digestion, and the wear of everyday stress.
Crisis & Depth
The 8th house: deep or systemic illness, surgery, crisis and regeneration.
Hidden Roots
The 12th house: immune vulnerability and the psychological roots of disease.
Where the chart becomes a plan.
A chart on its own is insight. What makes this work is what happens next: the constitutional picture becomes a living, practical, evidence-based plan for your body.
Medical astrology has always understood something modern medicine is only now returning to: that the psychological and the physical are one system. Jung saw it clearly, the chart maps first the psychic and then the physical constitution, because they are not separable. The same Mars that inflames the gut drives the temper; the same Saturn that stiffens the joints settles as worry and low mood. When I read your chart I am reading both at once, where stress originates in you emotionally, and exactly how it tends to surface in the body. That is the mind-body link made legible, and it is often the most resonant part of a reading.
This is the part I love most, and the part 27 years of nursing makes possible. The humoral reading tells us the direction your constitution tends to tip. A choleric fire signature that runs hot and inflamed asks for cooling, calming, anti-inflammatory support. A phlegmatic water signature that runs cold and damp asks for warmth, movement and stimulation. The chart does not just describe you, it points, with real specificity, at what will actually help.
From there I build the integrative plan the same way I would approach any patient: diet chosen for your temperament, herbs and supplements matched to your significators, movement and rhythm suited to your constitution. And I bring the clinical tools too, functional medicine testing, patterns of sensitivity, a proper history, so the astrology and the evidence check and sharpen one another. Neither works as well alone. Together they are remarkable.
The goal, in the old language, is to correct dyscrasia, to gently bring a constitution that has tipped out of balance back toward its own natural equilibrium. In modern terms, it is root-cause, whole-person care with a genuinely personalised starting map. That is what medical astrology gives that almost nothing else can: a place to begin that is truly, specifically yours.
A physician without a knowledge of astrology has no right to call himself a physician.

A simplified, illustrative example, not a real client, to show how the pieces come together from constitution to plan.
A fire-dominant chart running hot
Imagine a chart with the Sun and Mars both strong in fire signs, an Aries Ascendant, and Mars closely square the Moon. The elemental tally comes out heavily choleric, with fire well ahead of the other elements.
Choleric, hot and dry. A driven, high-energy constitution with strong digestive fire, but a natural tendency toward inflammation, heat and burnout when it tips out of balance.
Mars square the Moon flags the digestive and emotional link: heat and reactivity in the gut, a system that runs fast and inflames easily. The 6th house sign colours the daily-health picture.
Fire and Mars govern the liver, gallbladder, bile and muscles. These become the areas to watch and support first, the constitutional pressure points.
Cool and moisten. Bitter and cooling foods, anti-inflammatory and liver-supportive herbs, calming of the nervous system, and rest built in deliberately, checked against functional testing of inflammatory and liver markers.

I came for the astrology and stayed for the clinical depth. That combination of real nursing knowledge and constitutional insight is so rare.
Thank you for accompanying me, for your understanding, and for all the resources as I navigate this new path. It has meant more than I can say.
Common questions.
No, and I would never present it as one. I am a registered nurse and I take clinical care seriously. Medical astrology is educational and observational. It identifies constitutional patterns and tendencies, and it sits alongside conventional care, never in place of it.
No. Healthy scepticism is welcome. I came to this work through decades at the bedside, not away from them. Many clients arrive unsure and find the constitutional analysis remarkably accurate regardless. You need only be curious about yourself.
Your date, exact time and place of birth for the natal chart, plus a short health history. If your birth time is unknown, the Medical Astrology Guide app includes a rectification tool, or we can discuss it on your call.
A general reading looks at personality and life. Medical astrology reads the chart specifically for the body: your humoral temperament, the health houses, the body systems each placement governs, and how to support them. It is a clinical lens, not a character sketch.
Many people come to me with long-standing conditions conventional medicine has not resolved. I work alongside your existing medical team, never instead of it, and the programmes combine the chart with functional testing to build a fuller picture over time.
