Grape therapy

[3] Alternative medicine practitioners have recommended grapes and parts of the vine for treating various diseases, but there is no clinical evidence for any such effects.

[6] Ampelotherapy is offered in alternative medicine clinics and spas, particularly in Europe,[7] together with vinotherapy, a cosmetic treatment that involves rubbing grapes into the skin.

[8] The book was republished in 1989 as How to Conquer Cancer, Naturally, including an endorsement of Brandt's work by Benedict Lust, who is commonly referred to as "the father of naturopathy".

Although commonly used as a dietary supplement and studied in human trials at an amount much higher than can be consumed from drinking red wine, there is no high-quality evidence that resveratrol provides any benefits for cardiovascular risk factors.

[2][3] The diet proposed by Veit Kaufmann recommended the consumption of several pounds of freshly picked grapes a day, spread over 4 portions, combined with walks, sports and light healthy meals, over a course of three to six weeks in a spa, overseen by medical personnel.
