Commercially available anas barbariae is not vegan or vegetarian.
Anas barbariea, sold under the brand name Oscillococcinum, is a homeopathic treatment for flu symptoms. The "active" ingredient is an extract of Muscovy duck liver and heart. This preparation is usually sold as a "200C" preparation, meaning one part duck to 10^400 parts water. For reference there are about 10^80 atoms in the observable universe, which means what is actually being sold is just water. This makes it somewhat difficult to classify since even though the "active" ingredient is non-vegan, the actual product being sold is just water.
