Casules

Casules is a term that can refer to several different things, most commonly a type of capsule used for medicinal purposes or a small, decorative case. In the context of pharmaceuticals, a capsule is a dosage form for oral administration of a drug. It consists of a hard or soft outer shell, typically made of gelatin, that encloses a measured dose of medication, which can be in powder, liquid, or gel form. Capsules are designed to be swallowed whole and dissolve in the digestive tract, releasing the active ingredient.

Alternatively, "casule" might be used informally to describe a small, decorative box or container, similar to a locket or a pillbox, often used for holding personal mementos or small valuables. The etymology of the word is not definitively established, but it may derive from words relating to small cases or containers. In some regional dialects or older forms of English, the term might have seen varied usage. Without further context, it is difficult to pinpoint the exact meaning intended by the use of "casule." However, the most prevalent understanding relates to medicinal capsules.
