In a double - blind experiment, neither the participants nor the researchers know which group is getting the treatment (in this case, the medicinal soap) and which is getting the placebo. Here, the control group's ordinary soap acts as a placebo - like element. So, the test administrators can't know which group is getting the placebo to avoid bias in their evaluation.
