To the herbivore, Indole is mildly toxic — if not for the bacterial flora of the intestinal tract. For non-ruminants (such as humans), who have difficulty with Indole, its main effect appears to be intestinal, as it causes bloating and constipation.
Milk intolerance can be somewhat alleviated by neutralization to Indole. However, complete neutralization to milk sometimes requires several phenolics. Energique® has reported the effective use of Indole for allergic rhinitis and chronic fatigue, as is the case with many phenolics.
Energique‘s Indole Phenolic™ contains Indole 6x, 12x, 30x, 12c, 30c and distilled water. 20% ethanol.
