> Like we administered x mg of sulfer to the patient and they saw y outcome while patients not receiving sufler saw z outcome. When we stopped administering sulfer all patients saw z outcome seems to be isolating sulfer as causing y.

There is a reason we use placebos for control groups.

Uh, there's no requirement to use placebos or a control group.

For example, covid just uses a treatment group and considers the rest of the world as control.

Otherwise the sky may realize it's in the control group.

I'm more interested in the reason the OP had in mind. I don't think it's required that you have a placebo control group, but the OP might have a reason in mind that's something I haven't considered.
