It is relatively simple in the sense that you don't need a lot of setup other the equipment itself. # How to extract Caffeine from Tea (Classic DCM Method) Source: [https://www.youtube.com/watch?v=RIbff5iD0GQ&ab\_channel=NileRed](https://www.youtube.com/watch?v=RIbff5iD0GQ&ab_channel=NileRed) Note: Uses dichloromethane method (DCM) to extract caffeine. The setup is a bit more involved and requires attention to equipment use. The video shows the process step by step, but it uses 6 tea bags which is not something you would normally use for consumption. In addition, the yield extracted might be small. But disposal is of concern since DMC is carcinogenic. # The Extraction of Caffeine from Tea Leaves All Parts Source: [https://www.youtube.com/watch?v=8Z\_Ei1ITJpA&ab\_channel=BristolChemLabS](https://www.youtube.com/watch?v=8Z_Ei1ITJpA&ab_channel=BristolChemLabS) Note: Goes over each process and gives an overview of the equipment needed.
