magnesia
In athletic contexts, such as rock climbing, gymnastics, or weightlifting, magnesia refers to the dry white powder used to absorb sweat and increase friction on the hands. In these settings, it is often referred to simply as "chalk," though magnesia is the chemical substance.
In a medical context, the term is most commonly encountered in the phrase "milk of magnesia." This refers to a liquid suspension used as an antacid to treat heartburn or as a mild laxative. While "magnesia" can be used alone in a pharmacy or lab setting, the full phrase "milk of magnesia" is the standard colloquial term for the consumer product.
Because it refers to a chemical substance or a specific medicinal preparation, it is treated as an uncountable noun. You do not refer to "a magnesia" or "magnesias." Instead, use quantifiers like "some," "a bit of," or specific measurements like "a tablespoon of."
