I've been taking Noni for a few weeks and have concluded it contains
strong stimulant properties. As someone who watches his BP and
heart rate several times a week, it also appears to cause a rise in
both these numbers! Its effects are similar to taking a few shots
of espresso, although my caffeine days are behind me. My Noni
experiment is coming to an end, as I do not like the side effects.

It seems some of the reasons people take Noni is for energy and
weight loss. The stimulant effect probably explains why it works
for this. It also probably explains why people with other health
problems feel "better" in general.
