"Dokotela, umngani wami uthe waba ngcono zingakapheli isigamu sehora ngemuva kokuthatha iphilisi elinikezwe udokotela ngenxa yekhanda lakhe elibuhlungu. Kamuva, kwavela ukuthi kwakuyi-placebo nje equkethe ushukela nofulawa kuphela. Iphilisi likafulawa lingayelapha kanjani isifo? Ingabe kuyimilingo?" URuwan oneminyaka engu-30 ubudala wabuza uDkt. Priya ngokumangala emtholampilo wethu.
UDkt. Priya wamomotheka kancane wabe esechaza, "Ruwan, lokho kubizwa ngokuthi i-Placebo Effect. Lokhu akuwona umlingo.

I-placebo iwukwelashwa okungafanele okuqukethe noma yisiphi isithako esisebenzayo sokwelapha, ngokuvamile iphilisi elenziwe ngoshukela noma ufulawa, umjovo osekelwe emanzini, noma idivayisi engafanele.
Umphumela we-placebo uba lapho isiguli sinikezwa umuthi okuthiwa umuthi wangempela, bese isiguli sikholelwe ukuthi umuthi wangempela bese siwuthatha, futhi izimpawu ziyathuthuka empeleni.
Kwenzeka kanjani lokhu? Umongo Wokuziphendukela Kwemvelo
Ososayensi basikisela ukuthi lokhu kungenzeka ukuthi kungenxa yokuziphendukela kwemvelo kwabantu. Ezikhathini zasendulo, lapho indoda igula, yayithola ukunakekelwa nokunakekelwa kwamanye amalungu.
Uma kutholwa lokhu kunakekelwa, uhlelo lokuzivikela lomzimba luyakhuthazwa futhi amathuba okuphulukiswa kwalesi sifo ayakhula. Ngakho-ke, ubuchopho bomuntu buklanyelwe ukusheshisa inqubo yemvelo yokuphulukiswa komzimba lapho buthola isignali yokuthi othile uyayelapha.

Izingane zafakwa kulo mshini futhi zanikezwa ukwelashwa kokuskena okungamanga amasonto ayisithupha. Ngokumangalisayo, ngemva kwamasonto ayisithupha, izimpawu zezingane ezingaphezu kuka-70% zase ziphelile. Izingane zazikholelwa ukuthi zelashwe ngomshini wangempela, kodwa empeleni zelashwe ngamandla ezingqondo zazo.
