Mullein is a new found herb for me and I love it! Mullein in most parts of the US, is considered a large overpowering weed. It can be. It sows lots of seeds. But in a controlled garden environment it is possibly one of the best medicinal herbs to grow. This herb has long been used to help with upper respiratory infections, coughs, bronchitis. It acts as an expectorant.
One study was done harvesting and using the small mullein yellow flowers to help with ear infections. It showed significant improvement when compared to other options.
