How the magic works

I knew I would go to the country side to find out how the magic works but I failed. I have since talked it over with my workmates and friends and it is pretty amazing and hard to believe.
An elderly lady, close to the age my own grandmother told us in one of the eating places around my workplace that the medics and the arrival of the muzungu tampered with Ugandan medicine that was efficient and cost-effective. As we talked about this, I of course told them my story and the lady was bemused with me.
She asked where I came from, where I grew up from, my age and what I do. I told her everything as it is and when I noted that I was a professional medic, she touched my shoulder and said, 'my daughter, I do not blame you, I blame time that changes everything...to the benefit of the minority leading to the demise of may...' At this point, everyone simply kept quiet as we realized how time hinders progress of many than promote it. But subject to discussion of course.
She went on to tell us how fractures are treated. She said that the patient does not need to be where the doctor is but they agree on the time for treatment...that in such cases, the patient has to have people around them to hold them tight as the administration of the medicine is a painful exercise. Still, I confronted with a challenge of how this medicine is administered? How does it work without the physical presence of the patient and doctor? How can such a mechanism be replicated to cure other illnesses? How can it be upgraded to meet the current health demands?
These are challenges that I feel I need more insights on...I will continue the search for answers.
