Coptis root is a berberine containing herb (like Oregon Grape root) and is used much the same way against infections of all kinds. It is not only antibiotic in nature but also anti-tumor. Being a bitter compound, it increases your flow of blood and thus is beneficial for your liver. It is used for digestive problems, high fever, insomnia and heart palpitations. These are just a few of the wide ranging ailments that benefit from coptis root. This herb is more common in Chinese markets than the U.S. but it is well worth trying and using.
