Coffee is a beverage brewed from roasted, ground coffee beans.

The chemical complexity of coffee is emerging, especially due to observed physiological effects which cannot be related only to the presence of caffeine. Moreover, coffee contains an exceptionally substantial amount of antioxidants such as chlorogenic acids, hydroxycinnamic acids, caffeine and Maillard reaction products, such as melanoidins. [3]

Rubiaceae (/ r uː b i ˈ eɪ s iː ˌ iː,-s i ˌ aɪ /) is a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas , or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers.
Often, Marino says, people have mixed success with using coffee grounds for their plants, which she says could be due to the type of coffee grounds being used.
Acidosis, defined by blood pH below 7.35, is the most common disorder of acid–base homeostasis and occurs when there is an excess of acid in the body. In contrast, alkalosis is characterized by excessively high blood pH. Blood pH is usually slightly basic, with a pH of 7.365, referred to as physiological pH in biology and medicine.
