Coffee and tea are not only OK in moderation, but good for you. Both an organic fresh ground coffee and a green tea are high in antioxidants and other phytochemicals. Yes caffeine is an alkaloid stimulant and related to cocaine(full disclosure here), but in moderation should not be a problem. Everyone has a different tolerance for how much they can ingest. Too much is when you feel "jittery". It would take a ridiculous number of cups of coffee or tea to overdose! OK so I know the real question is how caffeine effects the Aura, Soul, Chakras, Astral Body. My Opinion is that as it only helps to release a little extra brain chemical that wakes you up, that already exists in the brain and already is doing that anyway, it is not a problem. It is not mind altering like LSD,Heroin,Cocaine, etc.
