The correct spelling of the term "calcii santonas" may seem intimidating at first, but a basic understanding of phonetics can shed light on its spelling. "Calcii" is pronounced "kal-see-eye," with emphasis on the first syllable. "Santonas" is pronounced "san-toe-nas," with emphasis on the second syllable. The addition of the "ii" and "as" endings are common in the Latin language, which this term originates from. So, the term "calcii santonas" refers to calcium-activated saccharomyces cerevisiae, a type of yeast used in the production of wine and bread.
Calcium santonate, anthelmintic in doses of gr. 1/2-1 1/2 (0.03-0.1).
