Criticism
There is no peer reviewed scientific evidence that crystal healing has any effect. It has been called a pseudoscience. Pleasant feelings or seeming successes of crystal healing can be attributed to the placebo effect, or the believers wanting it to be true and seeing only things that back that up; cognitive bias.
Crystal healing techniques are also practiced on animals, although some veterinary organizations, such as the British Veterinary Association, have warned that these methods are not scientifically proven and thus could cause greater harm if not used in conjunction with traditional medical care.

Famous quotes containing the word criticism:
“The critic lives at second hand. He writes about. The poem, the novel, or the play must be given to him; criticism exists by the grace of other men’s genius. By virtue of style, criticism can itself become literature. But usually this occurs only when the writer is acting as critic of his own work or as outrider to his own poetics, when the criticism of Coleridge is work in progress or that of T.S. Eliot propaganda.”
—George Steiner (b. 1929)
“... criticism ... makes very little dent upon me, unless I think there is some real justification and something should be done.”
—Eleanor Roosevelt (1884–1962)
“Homoeopathy is insignificant as an art of healing, but of great value as criticism on the hygeia or medical practice of the time.”
—Ralph Waldo Emerson (1803–1882)
