Phitkari Sufaid, globally known as White Alum or Potassium Alum, is a naturally occurring mineral salt that has been an essential part of traditional Unani and Greco-Arabic medicine for centuries. It usually appears as translucent white crystals or a fine crystalline powder. In Unani medicine, it is referred to as Shib-e-Yamani and is classified as having a "Cold and Dry" (Barid-o-Yabis) temperament. It is highly valued for its powerful ability to contract tissues, stop bleeding, and neutralize infections.
