Indicated Patterns by Affinity
👉 Indicated patterns describe the functional state of the body and its organs and/or tissues, showing whether they are dry, atrophied, too damp (pressure), stagnant, lax, inflammed, sluggish, tense or underactive. The Primary Indicated Pattern is the main state where this remedy works best. Secondary Indicated Pattern(s) are the patterns that often develop over time when the primary state is left unaddressed. The primary pattern must be supported first, as this allows the secondary patterns to naturally ease or resolve.
👉Affinities are the organ systems and tissues where the remedy acts most strongly.
-
Dysregulation (Primary Indicated Pattern) – When body signals shift unpredictably, creating alternating states of overactivity and fatigue.
Examples: Stress with alternating anxiety and exhaustion, restlessness that flips into sluggishness, difficulty focusing because the mind swings between “on” and “off.” -
Inflammatory (Primary Indicated Pattern) – When the immune system reacts strongly, creating heat, redness, or pain.
Examples: Red, irritated throat during colds, Inflamed sinuses with irritation, Mild fevers with immune reactivity.Auto-Inflammatory (Secondary Indicated Pattern) – When the immune system attacks excessively, creating cycles of self-driven inflammation.
Examples: Cyclical flare-ups of skin inflammation, Auto-inflammatory joint discomfort, Chronic irritation without clear external trigger. -
Excitation (Primary Indicated Pattern) – When vessels and circulation are overstimulated, creating reactivity or tension.
Examples: Stress-related high blood pressure, Palpitations during anxiety, Red or flushed face with nervous tension. -
Dysregulated (Primary Indicated Pattern) – When hormonal rhythms swing unpredictably between excess and depletion.
Examples: Irregular cortisol rhythm (wired at night, tired in the morning), Energy crashes after stress., Adrenal fatigue or stress-exhaustion cycles. -
Congestive (Primary Indicated Pattern) – When excess fluids builds up, slowing or obstructing respiration.
Examples: Boggy sinus congestion, wet cough with phlegm, heaviness in the chest during damp conditions.
