The correct spelling of the word "litharge plaster" is \ˈli-thərj ˈplas-tər\. The first part of the word, "litharge," is pronounced \ˈli-thərj\ and refers to a pigment made from lead monoxide. The second part of the word, "plaster," is pronounced \ˈplas-tər\ and refers to a mixture of materials used for coating walls and ceilings. Together, "litharge plaster" denotes a type of medical plaster made with litharge, often used in medieval times to treat wounds and abscesses.
Litharge plaster is a term commonly used in the field of medicine and pharmacy. It refers to a type of medicinal adhesive plaster that contains litharge as its main ingredient. Litharge is a yellowish or reddish form of lead oxide that is derived from the oxidation of metallic lead.
The plaster is made by combining litharge with other materials such as olive oil, resins, and wax, which are mixed to create a thick form of adhesive. This adhesive is then spread onto a suitable backing material, typically muslin or a similar fabric, creating the plaster.
Litharge plaster is known for its adhesive properties, making it ideal for use in medical applications. It is commonly used in the treatment of various skin conditions, such as wounds, cuts, and ulcers. The plaster is applied directly to the affected area, adhering to the skin and providing a protective barrier.
The litharge in the plaster is believed to have antiseptic properties, helping to prevent infection and promote healing. Additionally, the adhesive nature of the plaster helps to keep the wound or affected area clean and secure.
It is important to note that care should be taken when using litharge plaster, as it contains lead, which is a toxic substance. Proper precautions should be followed, and it should only be used under the guidance of a healthcare professional.

The word "litharge" originates from the Greek words "lithos" meaning "stone" and "argos" meaning "white". It refers to a yellow or orange mineral form of lead(II) oxide, which has been used for various purposes throughout history, including in the production of pigments, glass, and ceramics.
The term "plaster" comes from the Old English word "plæstrian", meaning "to plaster" or "to cover with plaster", which ultimately derives from the Latin word "emplastrum" and the Greek word "emplastron", both meaning "plaster". Plaster typically refers to a mixture of materials (such as gypsum, lime, sand, or cement) used for coating walls or creating molds.
Therefore, "litharge plaster" refers to a plaster made by incorporating litharge, or lead(II) oxide, into the mixture.
