♌ Mag phos: The Motor. The Motion. The Leo Salt. 🦁
Leo governs the heart and motor system.
Mag phos governs the nerves, contractions of the organs, and the muscles through which energy becomes movement.
Most people think of Leo as the sign of confidence, courage and self-expression. The performer, the leader, the radiant personality ruled by the Sun.
Yet beneath these familiar qualities lies a more fundamental principle.
Leo represents the power to act.
An intention may arise within the mind, but unless the nervous system can carry that impulse into the muscles, it remains only an intention. The brain issues the instruction, the motor nerves transmit it, the muscles respond, and something that began invisibly becomes visible as movement.
Carey and Perry describe this as the physiological meaning of Leo:
“Motion is the interpretation of Leo - Motion, not e-motion.”
Within their zodiacal anatomy, Aries is the cerebral generator from which the vital current begins. Leo then brings that current into physical expression through the heart, motor nerves and muscular system.
If Aries generates the impulse, Leo puts the organism into motion.
Mag phos stands between the two, allowing nervous energy to become living action.
🔬 Core Biochemic Functions
The classical biochemic texts associate Mag phos primarily with:
▪ The white fibres of the nerves
▪ The motor nerves, brain and spinal cord
▪ Skeletal muscle, smooth and involuntary muscle
▪ The muscular walls of hollow organs
▪ The intestines
▪ The heart muscle
▪ Activates over 300 enzymes
▪ Cellular energy and ATP production
It influences:
▪ Nerve-to-muscle communication
▪ Muscular contraction and relaxation
▪ Normal muscular tone
▪ Rhythmic involuntary movement
▪ Intestinal peristalsis
▪ Nervous excitability
▪ The conversion of cellular energy into movement
▪ Cholesterol and blood pressure balance
▪ Ability to absorb and utilise calcium
The older writers compared the nerve fibres to telegraph wires, each carrying a particular current through the organism. Sensory nerves carry information towards the brain, while motor nerves carry instructions outward, telling the muscles when and how to move.
Mag phos was particularly associated with this motor function: the place where the message carried by the nerve becomes an action performed by the body.
And this mineral was the chief remedy in issues arising here, like in St Vitus's dance ( a condition causing jerky, uncoordinated movements of the arms, legs, and face).
Modern physiology supports the broader mineral principle beneath this idea. Magnesium is involved in nerve conduction, muscular activity, cellular energy production and normal cardiac rhythm.
Mag phos is therefore not merely “the muscle salt.”
It is the mineral of controlled motion.
♌ Leo & the Motor System
Leo rules:
▪ The heart
▪ The spine
▪ The motor nerves
▪ Muscular power
▪ Circulation
▪ Vitality
▪ Courage
▪ Directed action
Leo brings power out from the centre and puts it to work.
This can be seen in every deliberate movement. A hand reaches, a foot steps forward, the spine straightens and the voice projects itself into the world. None of these actions begins in the muscle alone. Each begins as an invisible nervous instruction that must be received, translated and performed.
Mag phos makes that translation possible.
The connection with Aries and Kali phos is particularly important here. Kali phos is associated with the grey matter and the generation of nervous energy, while Mag phos is associated with the motor fibres and muscles that respond to it.
Kali phos provides the nerve spark.
Mag phos turns that spark into motion.
❤️ The Heart of Leo
The heart is the great muscular centre of Leo, but its strength does not come from contraction alone.
The heart contracts to send blood onwards, then releases so that it may fill again. This alternation between effort and rest continues throughout life. If the heart remained permanently clenched, its strength would become useless. Its power depends upon rhythm.
Mag phos expresses this same principle throughout the muscular system.
Without contraction, the body cannot act. Without relaxation, it cannot act again. Movement depends upon the ability to generate force, sustain it for the necessary moment, and then release it.
This is the deeper relationship between Leo and Mag phos, Leo is not simply raw power. It is power brought under direction.
Mag phos is not simply muscular contraction, It is the regulation of contraction so that force becomes useful movement rather than tension or spasm.
⚡ When Motion Becomes Spasm
Mag phos deficiency may present as:
▪ Muscular cramps
▪ Menstrual cramping
▪ Abdominal or intestinal colic
▪ Stomach spasms
▪ Hiccups
▪ Eyelid or facial twitching
▪ Writer’s cramp
▪ Restless or jerking muscles
▪ Spasmodic coughing
▪ Neck tension and stiffness
▪ Sharp, shooting or electric-like pains / Neuralgia
Although these symptoms occur in different parts of the body, they reveal the same underlying disturbance.
The muscles contract too suddenly, too strongly or for too long. The nerve impulse is no longer being translated into smooth, rhythmic motion. Energy that should have produced useful movement becomes trapped within the tissues as tension.
This is why Mag phos is traditionally known as the great antispasmodic tissue salt.
It does not merely stop movement, movement itself is not the problem.
The problem is movement that has lost its rhythm.
A healthy intestine must contract and release to move its contents forward. The uterus must generate muscular force in an organised pattern. The heart depends upon electrical and muscular activity occurring in a precise sequence.
When rhythm is lost, power becomes pain - Mag phos helps restore controlled movement.
🌡️ The Mineral That Seeks Warmth
Mag phos has one of the clearest reaction patterns in the biochemic system.
Aggravated by:
▪ Cold air, wind
▪ Cold applications
▪ Sudden chilling
▪ Night-time
▪ Nervous strain
▪ Prolonged muscular effort
▪ Gentle touch
Relieved by:
▪ Warmth
▪ Hot applications
▪ Firm pressure
▪ Rubbing or massage
▪ Bending or drawing the painful area inward
▪ Resting the affected muscles
Cold causes tense fibres to contract more tightly, while warmth encourages them to soften and release. This is the basis of the traditional “Hot 7,” in which Mag phos tablets are dissolved in hot water and sipped slowly. This also brings more blood to the buccal mucosa allowing for faster uptake and quicker mineral delivery to targe areas (and you can do this with any tissue-salt!)
The solar correspondence is beautifully simple.
Leo is ruled by the Sun - Mag phos seeks warmth.
Both reveal heat as a force that restores movement where the organism has become cold, rigid or painfully contracted.
👁 Facial Signs
The traditional facial sign of Mag phos is known as Magnesia red.
It may appear as:
▪ Rounded patches of redness on both cheeks (Like the traditional Santa Claus)
▪ Sudden flushing / blushing during emotional or nervous tension
▪ Redness following alcohol
▪ Twitching around the eyes or mouth
Unlike the ruddy redness associated with Ferr phos that is also hot to touch, Magnesia red may appear and disappear quite suddenly and is without heat.
It flashes beneath the skin like nervous fire becoming briefly visible before fading out.
When this redness occurs alongside cramping, twitching, shooting pains and marked relief from warmth and pressure, the Mag phos pattern becomes much clearer.
🧠 The Mental–Physical Parallel
The body does not experience emotion as something separate from its biology.
Fear prepares the legs to run. Anger tightens the jaw and arms. Worry contracts the stomach. Excitement accelerates the heart. Every strong emotional response produces some form of physical preparation.
When the expected action does not occur, or when the nervous system is unable to settle afterwards, the muscular command may remain active.
The shoulders stay raised, the jaw continues to grip, the abdomen remains guarded. The body stays ready to act long after the moment has passed.
The deeper Mag phos pattern may therefore include:
▪ Difficulty relaxing after stress
▪ Remaining physically braced after danger has passed
▪ Muscular tension during nervous strain
This is the Leo force caught inside the body.
Leo’s lesson is not simply to develop power. The power is already present. Its lesson is to direct that power wisely, express it without exhausting the organism, and allow it to rest when its work is complete.
A heart must release before it can fill again, a muscle must soften before it can produce another useful movement.
Even the lion rests beneath the Sun 😉
🦁 Mag phos — The Motion of Leo
Leo governs the heart and motor system.
Mag phos governs the fibres through which nervous energy becomes muscular action.
Without it:
▪ Nerve force becomes irregular
▪ Muscles contract without releasing
▪ Movement becomes painful or spasmodic
▪ Vitality is trapped as tension
▪ The body struggles to return to rest
With it:
▪ The nervous signal travels clearly
▪ Muscles respond rhythmically
▪ Contraction is followed by release
▪ Energy becomes coordinated movement
▪ Strength can be expressed without strain
Aries and Kali phos generate the nerve spark - Leo and Mag phos carry that spark into physical life.
The heart maintains the rhythm, the motor nerves carry the command, and the muscles give it form.
Leo is vital force brought to fruition.
Mag phos is that force made useful—not trapped as tension, nor scattered through uncontrolled reaction, but expressed as life in motion. 🦁🔥
