Bitter Almond Overview
Bitter almond is a variety of almond. It has traditionally been used as an antispasmodic, narcotic, cough suppressant, and to treat itching.
Bitter almond oil contains a toxic compound called amygdalin, which is metabolized to hydrocyanic acid (HCN) in the body. This chemical slows down the nervous system and can cause breathing problems. It must be used cautiously. It should not be confused with other types of almond, like sweet almond, which is safe to consume.
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.
