I came across a substance awhile ago, that was transparent as far as i could tell. The substance had a lubricant feel to it and was tasteless as far as i remember. When the substance dried onto skin, formed sort of a gluey crusty thin layer that washed away with water easily.

Directly after consuming causes sleepiness, after waking up I deficated black tar like feces. BUT I felt amazing, as if the substance sucked all the toxins out of my body. Almost like it was an antidote. If anyone could please help me at all, point me in any kind of direction.
