For over 150 years, Insan Korean Medicine has preserved one of the rarest and most mysterious purification arts — the Beopje (법제) method. Among its many alchemical secrets, one stands out for its brilliance and scientific elegance: the egg-white purification of Damban (Chalcanthite, CuSO₄·5H₂O), which transforms into Nandamban.
While Chalcanthite is known as a striking blue copper-sulfate crystal, its raw form is toxic. The true mastery lies not in finding the mineral but in making it safe for the human body — a breakthrough first achieved by Master Kim Il-Hoon (Insan), the founder of Insan Medicine.
The Traditional Egg-White Purification (Beopje) Process
The Beopje (法製) purification is a sacred art of Korean medicine — a step that determines whether a natural substance can be safely used for healing.
Here’s how Insan’s traditional Nandamban Beopje works:
Selection of Pure Chalcanthite (Damban):
Only naturally crystallized blue Chalcanthite is chosen, free from contamination or synthetic processing.
Egg-White Fusion:
The mineral is carefully mixed with the whites of fresh eggs — rich in albumin proteins that naturally bind and neutralize impurities.
24-Hour Heat Purification:
The mixture undergoes a 24-hour low-heat refinement that extracts harmful copper ions while preserving beneficial trace minerals.
Crystallization and Drying:
After purification, the refined substance is gently dried, forming Nandamban — a mineral reborn through the harmony of fire, water, air, and patience.
This transformation is not only chemical but also philosophical: Damban’s raw toxicity is tamed by purity (egg white) and discipline (heat). It miracle capsule contains nandamban perfectly reflects Insan’s belief — turning danger into healing through balance with nature.
Why Nandamban Matters Today
Modern science now confirms what Master Insan understood centuries ago. The egg-white process aligns with protein-assisted detoxification, a biochemical principle where albumin binds with heavy metals to neutralize toxicity.
That’s why Nandamban became the core ingredient in the Miracle Capsule — a natural supplement uniting Nandamban and 9× Roasted Bamboo Salt. Together, they embody Insan’s vision of purification, protection, and renewal.

The Philosophy Behind Nandamban
In Insan’s worldview, purification is more than removing toxins — it’s a spiritual and energetic transformation.
Just as bamboo salt is reborn through nine fiery cycles, Damban is reborn through purification and patience.
Both symbolize that true healing begins with transformation — from raw to refined, from impure to pure, and from pain to vitality.
Final Thoughts
Nandamban represents the heart of Insan’s philosophy — where nature, science, and spirit converge. Through the egg-white Beopje method, Insan transformed a once-toxic mineral into a purified source of balance and protection for the human body.
