I don't think Mountain Rose Herbs sells tinctures.  At least when I did a search within their website I couldn't find any.

Did you actually see tinctures for sale on that website?

Edit:  I just found where they have made videos on YouTube showing how to make a tincture.  This is an incredible find for     those of us who want to learn.  Thanks for asking this question, it made me go on a search LOL.

Edit Again:  Just wanted to say that Uny macerates the mixture in the VitaMix after 3 days then puts it all back in the jar. In this video they don't do that, but I'd go with Uny's way.

This is my last Edit I promise LOL.  I did go back and look and found the tinctures, I don't know why they didn't come up when I put "tinctures" in their search box.  Anyway, I haven't used MR tinctures but they just can't be any better than Uny's so I'm sticking with hers plus I'm going to do some of my own eventually.

I have not tried their products, so I have no idea of their quality, but I did find something interesting I didn't think of on the company page:

"Eclectic chooses to utilize alcohol for their extracts that is made with certified organic grapes. The advantages of organic alcohol over conventional grain alcohol are; Grape alcohol is hypo-allergenic. Studies have shown that corn alcohol passes the allergens of corn to the spirit that is derived from corn. By using grape alcohol Eclectic is able to bypass any corn allergy problems which may be aggravating the health condition."
 
"Corn is also one of the most sprayed crops in the US. Each year millions of pounds herbicide and pesticides are sprayed on corn crops. We feel by using certified organic grapes for our alcohol we are offering the consumer a truly organic product as well as an environmentally sound product."

Valid points or sales gimmick?
