    "device_name": "Allium-Based Preservation Process",
    "goal": "To preserve animal and vegetable matter indefinitely and to restore it to its original condition when needed.",
    "problem_addressed": "Decomposition and deterioration of biological, organic, and cultural artifacts (e.g., tissue specimens, paper, cloth, paintings).",
    "concept_summary": "The invention saturates the target material with an oil derived from Allium plants (garlic/onion). The oil's germicidal and restorative properties halt bacterial decay. After saturation the material can be dried for long-term storage and later re-hydrated in water to restore pliability. Fixatives such as alcohol or formaldehyde may be added to improve penetration in low-porosity tissues.",
    "detailed_description": "The process begins by extracting oil or juice from garlic (Allium sativum) or related Allium species. The oil may be used in a volatile (vapour) or fixed (liquid) state, at any temperature between freezing and boiling. The material to be preserved is saturated by immersion, injection, dipping, or exposure to vapour until no further absorption occurs. Once saturated, the material can be dried and stored indefinitely. To restore the material, it is immersed in water, which washes out the germicidal agent, returning the specimen to its original pliability and volume. For tissues that collapse before the oil penetrates, a fixative (e.g., alcohol, formaldehyde) is mixed with the oil to speed cell entry. The method is applicable to animal bodies, anatomical specimens, paper, manuscripts, paintings, wood, silk, and other organic substrates.",
