Indigo Drops gets its name from "wild indigo", an adaptogenic plant with an affinity for the upper part of the body, especially the respiratory system. Indigo Drops is a potent antiviral and lymph stimulating formula.

It was developed in response to needs for effective lymphatic relief where the cause of the congestion is presumed to be an underlying infection, often chronic and undiagnosed. It works best when combined with one of Ingrid's lymph stimulating teas.
