安慰剂的魔力

由Olly Bootle执导，史蒂文·伯克夫主演的安慰剂的魔力是一部英国纪录片电影，讲述了They are the miracle pills that shouldn't really work at all. Placebos come in all shapes and sizes, but they contain no active ingredient. Now they are being shown to help treat pain, depression and even alleviate some of the symptoms of Parkinson's disease. Horizon explores why they work, and how we could all benefit from the hidden power of the placebo.
