Query: Tastes bitter & doesn't work

This product took about a week to arrive which is fairly slow, but it was well packaged.The herbs don't seem to really work for my hyperthyroid condition, which is a shame, because the bottle is pretty expensive.The tincture smells quite strong & tastes very bitter.I wouldn't recommend it; I'm going to stick with taking ThyroSoothe, which is more expensive but it actually works for my symptoms.
