You can use medicine energy with VK provided you know thats exactly what you require, because VK will only mimick it.
For antibiotics, there are different antibiotics for different infections. Also many people develop resistance to antibiotics, so same antibiotics don’t work for them !!
Thats how sometimes Doctors keep changing medicines till they know what suits the patient.
Many times medicines don’t work if there is emotional trap. So they would not work even if given through VK. When VK mimics it will mimic what would actually happen with physical dose.
Do keep the intention with safety and security for medicines.
One person was mimicking energy of an anti fungal drug for an infection, but he was using an incorrect brand name, that was actually for a medicine working on brain for depression.
Be sure what you want to mimick.
