Squill Overview

Squill Squill is a type of bulbous perennial plant, also known as sea onion or sea squill, that is native to the Mediterranean region and the Black Sea coast. It has been used in traditional medicine and contains a substance known as scillaren A, which is believed to be responsible for its medicinal properties. Squill has been used for a variety of purposes, including as an expectorant to relieve coughs, as a diuretic to increase urine production and as a 'cardiac tonic', to stimulate the heart and improve circulation. It has also been used topically for hair loss. However, it is important to note that squill contains cardiac glycosides that can be toxic and may cause serious side effects, such as an irregular heartbeat, low blood pressure, and death. It must be used cautiously.

Peginterferon alfa-2b Overview

  • Peginterferon alfa-2b is used alone or in combination with ribavirin (a medication) to treat chronic (long-term) hepatitis C infection (swelling of the liver caused by a virus) in people who show signs of liver damage and who have not been treated with interferon alpha (medication similar to peginterferon alfa-2b) in the past. Peginterferon alfa-2b is in a class of medications called interferons. Peginterferon alpha-2b is a combination of interferon and polyethylene glycol, which helps the interferon stay active in your body for a longer period of time. Peginterferon alpha-2b works by decreasing the amount of hepatitis C virus (HCV) in the body. Peginterferon alfa-2b may not cure hepatitis C or prevent you from developing complications of hepatitis C such as cirrhosis (scarring) of the liver, liver failure, or liver cancer. Peginterferon alfa-2b may not prevent the spread of hepatitis C to other people.
