A long time ago before @Luther12 spend half a life time in medical school to come and issue us with fake antibiotics, below is how our fore fathers used to do it
the pharmacist below, used to collect herbs/poisons here and there and ground them and as long as they were extremely bitter, it would cure something and for sure they did, otherwise we all wouldn’t be here

Now we all know that before going to the pharmacist, first you have to go through the consultancy room, back in the day they didnt have x-ray , y-ray and z-ray machines.
it all revolved around finding out who is making you sick.
below is a photo taken in consultancy room one, notice the paraphernalia, of interest is the white chalk (you can only get it in MT kenya and Kilimanjaro

if consultancy room 1 was occupied or you had been infected with Christianity, you would be send to room 2, where there was the best of the best Kamba diviners. she would communicate with the ancestors (wangwana) via the use of a bow and guard (strumming) and immediately establish a vsat link and you got your diagnosis. (the bible was just place there to soothe your christian ego, word was that she also had a direct communication link to Moses, Abraham and all prophets)

His name was Bengei (better than house M.D) and his procedure for treating mad people included burring the patient alive. below photo shows him at work making the necessary preparations to bury a patient
