Re: Hey HV do you know this herb?Seems a bit pricey.

Technically this is not an herb, no more than oil or shale are herbs anymore.

I have never worked with this, but I have been thinking about getting some for a while after seeing some of the information on the humic and fulvic acids, which are also extremely expensive.  I have seen this in my Ayurvedic catalogs but have never paid attention to the price since I am not going to work with it at the moment.
