In homoeopathy, the selection of potency is crucial and depends on various factors, including the nature of the disease and the patient’s overall condition. When it comes to chronic diseases with prominent mental symptoms, lower potencies are often preferred for several reasons:

1. Gentle and Gradual Action: Lower Potencies: Remedies with lower potencies (e.g., 6X, 6C) act more gently and gradually on the body. This is particularly important for chronic conditions, where a slow and steady approach helps in addressing deep-seated imbalances without causing sudden changes that might overwhelm the patient’s system.

2. Sensitivity of the Vital Force: Chronic Conditions: Chronic diseases often indicate a weakened or sensitive vital force. Lower potencies are less likely to provoke a strong reaction from the vital force, making them more suitable for patients with long-standing conditions.

3. Mental and Emotional Balance: Mental Symptoms: Mental and emotional symptoms are deeply connected to the vital force. Lower potencies are believed to work harmoniously with the vital force, helping to restore balance without causing excessive aggravation of mental symptoms.

4. Individualization: Holistic Approach: Homoeopathy emphasizes individualized treatment. The choice of potency is tailored to the patient’s unique symptom picture, including their mental and emotional state. Lower potencies are often more adaptable to the nuances of chronic conditions with mental similarities.

By using lower potencies, homoeopaths aim to provide a gentle, gradual, and individualized approach to treatment, ensuring that the patient’s mental and physical health is supported without causing undue stress or aggravation.
