Product review (1 stars): Based on active ingredients, this product is outrageously expensive
This costs about $300 per ounce of active ingredient. That puts it between number 5 and 6 on a list of 10 most expensive liquids, right between Chanel No. 5 and horseshoe crab blood. If you buy Essick brand, you can get it for $23 per ounce of active ingredient or better.
