You can make a lab in your home by taking shot glasses or very small glases that nobody drinks out of for containers. To get all the ingredients, well, experiment with the spices, oils and left over foods that lie around. They all react, imagine the medicines you could make with spices?
Spices make the best medicine because they burn things like cells. If you were to experiment with a blood sample and take some tupperware containers - not as good but good enough - you could treat the infected blood, that nobody has anything better to do with, and add things to it.
If you were to go to class and experiment there, you would be able to see if things work or not, and how adding spices from your kitchen affects the diseases. Chicken soup for a cold? Think harder... um...
