Why Candrāṁśu Rasa Is Used – Classical Reasoning
The Bhāṣajya Ratnāvalī describes Candrāṁśu Rasa as “रसमभ्रमयो वड्गं गन्धकं कन्यकाम्बुना । मर्दयित्वा वटीं कुर्याद् गुञ्जाद्भ्रमाणतः” (shloka 85) – a formulation that softens the uterine wall and removes the “moon‑like” (candrāṁśu) feeling of heaviness.
- Rasa-pāka (metallic processing): The combination of pārada with iron, tin, and mica bhasmas creates a fine, bio‑available mineral matrix that can penetrate the deep tissues of the uterus.
- Balancing Vata-Kaphas: The cooling effect of vaṅga and gandhaka together with the warming kanyakāmbu offers a balanced virya (potency) suitable for Vata‑dominant uterine cramps while preventing excess heat that could aggravate Kaphic stagnation.
- Raktas-shuddhi (blood purification): Abhraka and gandhaka are traditionally regarded as blood‑purifying agents, essential for healthy placental function and the removal of ama that may cause pain.
- Mardana process: The intensive grinding (mardana) is believed to energise the metals, making the final product more therapeutic for the delicate uterine tissues.
