Oregon Grape Overview

Oregon Grape Oregon grape (Mahonia aquifolium) is a perennial shrub that is native to the Pacific Northwest region of the United States, including Oregon and Washington. It is also found in parts of Canada. The plant is a member of the barberry family (Berberidaceae) and is closely related to the holly plant. Oregon grape is often grown as an ornamental plant due to its attractive foliage and colorful berries. It is also used medicinally and is believed to have astringent, tonic, and anti-inflammatory properties. The root of the plant is used to make a herbal extract that is used to treat a variety of ailments, including skin conditions, digestive problems, and respiratory conditions. Most of the positive evidence for a medicinal effect is with topical applications as some research has shown topical preparations may modestly decrease the severity of psoriasis. It is important to note that the berries of the plant can be somewhat bitter and may contain toxins, so they should be eaten in moderation.

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.
