Grape therapy

Grape therapy or grape diet, also known as ampelotherapy, is a diet that involves heavy consumption of grapes, including seeds, and parts of the vine, including leaves, that is a form of alternative medicine. The concept was developed in 19th-century Germany in spas such as Bad Duerkheim and Merano.^[1] The concept has no scientific basis and is regarded as quackery by scientific institutions like the American Cancer Society.^[2]
