There are two main types of heart failure: heart failure due to left ventricular dysfunction and heart failure with normal ejection fraction depending on if the ability of the left ventricle to contract is affected, or the heart's ability to relax.
Gruit is a term that refers to both the mixture of herbs and spices used to flavor beer or mead as well as the alcoholic beverage flavored with such herbs and spices. Thereâs no one particular mixture of herbs and spices used in gruit â every brewer had their own proprietary combination.
The exclusive use of gruit was gradually phased out in favor of the use of hops alone in a slow sweep across Europe occurring between the 11th century (in the south and east of the Holy Roman Empire) and the late 16th century (Great Britain).
