Feketevíz

Feketevíz is a term with multiple meanings, primarily referring to a type of dark water found in certain natural environments or a specific product associated with traditional remedies.

In a natural context, "feketevíz" can describe water that appears black due to a high concentration of dissolved organic matter, such as tannins from decaying vegetation. This is commonly observed in peat bogs and some forest streams. The dark color does not necessarily indicate pollution but rather the natural processes occurring in those ecosystems. Such waters can have unique chemical properties and support specialized flora and fauna.

The term also refers to a traditional Hungarian remedy. Historically, feketevíz was a preparation made from various herbs and minerals, believed to have medicinal properties. Its exact composition and intended uses varied over time and by region. These traditional preparations were often homemade and passed down through generations. While the practice of using feketevíz as a remedy is largely historical, it remains a part of folk medicine traditions in some areas. The specific ingredients and efficacy of such preparations are subjects of historical and ethnobotanical interest rather than scientific medical validation.
