Angostura bitters is a flavored bitters made from a secret blend of herbs and spices, including angostura bark. It is primarily used as a flavoring ingredient in cocktails, such as Manhattan, Old Fashioned, and Pink Gin, to add a bitter taste.
In traditional medicine, angostura bark is used to treat digestive problems, such as indigestion, bloating, and nausea. However, there is limited scientific evidence to support these uses and the safety and efficacy of angostura bitters as a medicinal product have not been established.
It is important to note that consuming large amounts of angostura bitters can be toxic, as it contains high levels of alcohol and bitter compounds. If you have any health concerns, it is best to speak with a healthcare provider.
