Psorinum is a homeopathic remedy prepared from the purulent matter of psoriatic scales, primarily used in homeopathic medicine to treat a range of chronic conditions. The remedy is based on the principle of "like cures like," where a substance that causes symptoms in a healthy person is used to treat similar symptoms in a sick person. In Hebrew, it is referred to as פסורינום. The name is derived from the Greek word "psora," meaning "itch," which is associated with the skin condition psoriasis. Psorinum is often used to address conditions such as eczema, asthma, and various skin disorders, as well as general debility and chronic fatigue. It is also employed in cases where the individual exhibits a strong sensitivity to cold air and a tendency towards chronic infections. The remedy is available in various potencies and forms, including pellets, liquids, and creams, and is administered based on the individual's specific symptoms and overall health profile.
