Cnicin, whose brute chemical formula is: C20H26O7, is the main component of bitter substances, more responsible for the properties of the holy cardo (Centaurea benedicta (L.) L., 1763).
The cnicina is a bitter glycoside (sesquiterpenic lactone) extracted from the flowering flowers of this plant and used for its eupeptic properties. This compound was isolated for the first time in 1841 by Nativelle. In 1955 it was reported that the cnicina is endowed with antibiotic activity especially with regard to Gram negative bacteria.
The use of products and preparations based on cnicina should however be subjected to medical advice as they are reported allergic reactions in predisposed individuals (individual hypersensitivity to Asteraceae).
In fact, due to the presence of cnicina, high doses (more than 5 grams of drug per cup of infusion) irritate the gastric mucosa and cause vomiting.
