Cinchona Overview

Cinchona Cinchona is a genus of flowering plants belonging to the Rubiaceae family. It contains around 25 different species and is native to the Andes mountains of South America. One of the most well-known species is Cinchona calisaya. The bark of cinchona is a source of quinine, an alkaloid that has been used for centuries to treat malaria. Cinchona bark is also used in traditional medicine for a variety of other ailments, including muscle cramps, restless legs, fever, arthritis, and digestive disorders. As Cinchona contains quinine, it is sometimes used as a flavoring on tonic water and alcoholic drinks. Cinchona bark has been shown to contain, on average, 5% to 15% quinoline alkaloids.

Oseltamivir Phosphate Overview

  • Oseltamivir is used to treat some types of influenza infection ('flu') in adults, children, and infants (older than 2 weeks of age) who have had symptoms of the flu for no longer than 2 days. This medication is also used to prevent some types of flu in adults and children (older than 1 year of age) when they have spent time with someone who has the flu or when there is a flu outbreak. Oseltamivir is in a class of medications called neuraminidase inhibitors. It works by stopping the spread of the flu virus in the body. Oseltamivir helps shorten the time that flu symptoms such as a stuffy or runny nose, sore throat, cough, muscle or joint aches, tiredness, headache, fever, and chills last. Oseltamivir will not prevent bacterial infections, which may occur as a complication of the flu.
