Ar gydymo kristalai iš tikrųjų veikia?

If you’re into the world of alternative medicine, you’ve probably heard about crystals. The name given to some minerals, as quartz, or amber. People believe in beneficial health properties.

Holding crystals or placing them on your body is thought to promote physical, emotional and spiritual healing. Crystals supposedly do this by positively interacting with your body’s energy field, or chakra. While some crystals supposed to alleviate stress, others purportedly improve concentration or creativity.

Unsurprisingly, researchers have carried out few conventional studies on crystals. But one, conducted back in 2001, concluded that the power of these minerals is “in the eye of the beholder.”

Romoje vykusiame Europos psichologijos kongrese 80 žmonės užpildė klausimyną, skirtą vertinti jų įsitikinimų lygį paranormaliuose reiškiniuose. Vėliau tyrimo komanda paprašė visus medituoti penkias minutes. Laikydami tikro kvarcinio kristalo arba suklastoto stiklo kristalo.

Paranormalus įsitikinimas

Afterward, the participants answered questions about the sensations they’d felt while meditating with the crystals. Both the real and fake crystals produced similar sensations. And people who tested high in the paranormal-belief questionnaire tended to experience greater sensations than those who scoffed at the paranormal.

“We found that lots of people claimed that they could feel odd sensations. While holding the crystals, such as tingling, heat and vibrations. If we’d told them in advance that this is what might happen,” says Christopher French, a professor of psychology at Goldsmiths, University of London. “In other words, the effects reported were a result of the power of suggestion, not the power of the crystals.”

Lots of research shows how powerful the placebo effect can be. If people believe that a treatment will make them feel better. Many of them do feel better after they have had the treatment. Even if scientists proved that it’s therapeutically worthless.

His take is one you would expect from a scientist. And yes, it’s almost certainly accurate to say that crystals do not themselves possess any of the mystical health properties attributed to them by users.

But the human mind is a powerful thing, and it’s trickier to say flatly that crystals don’t work, if you define “work” as providing some benefit.

“I think that the public and medical community’s perception of the placebo is something that is bogus or fraudulent,” says Ted Kaptchuk, professor of medicine at Harvard Medical School. But Kaptchuk’s research on placebo suggests that its therapeutic actions can be both “genuine” and “robust”. While he hasn’t studied crystals, and will not comment on their legitimacy or anything to do with alternative medicine. Kaptchuk has written that a therapy’s built-in placebo effect can be considered a distinct aspect of its efficacy, and that placebo-induced benefits should be promoted, not dismissed.

Many physicians do believe in the power of placebo. A 2008 BMJ study found that roughly half of the physicians surveyed reported using placebo treatments to help their patients. Typically, a doctor recommend an over-the-counter pain reliever or vitamin supplement. Even though neither was indicated for the patient’s symptoms. Most viewed the practice of prescribing placebo treatments as ethically permissible, the authors concluded.

Holding a crystal, of course, is not the same as swallowing an Advil. Don’t expect your doctor to recommend crystals at your next visit. From the standpoint of conventional medicine and evidence-based science, the existing research suggests they’re akin to snake oil. But research on the placebo effect suggests that even snake oil can have benefits for those who believe… read more >>
