I personally take them internally every day. In the morning I take Digestzen, DDR Prime, Frankincense, and Turmeric. At night I take the same thing, except I switch out the Frankincense for Copaiba. And, of course, I drink Lemon in my water all the time. Great way to detox while getting your daily water requirement.
