Yes I suspect Liver Care does contain mercury. When I take it I get very discernible symptoms of mercury (such as feelings of fear) as I am particularly sensitive to mercury.
I must say, however, that it is excellent at opening up and clearing the liver though. But not worth the heavy metals.
Consider their AMLA or TRIPHALA products - it is of a dark silver grey color. Why is that so? The amla fruit itself is light green, and triphala products from other companies are of a light color, not dark. Could it be that Himalaya engages in Rasa Shastra, an Ayurvedic practice of deliberately adding heavy metals?
