If you have never had Mullein whilst you have been congested you are really missing out. Mullein is great at helping ease sinuses and helping coughs be more productive in bringing up the chest and throat gunk when you're sick. I have had a bottle of liquid for some time now and it has been alright, but using the dropper for measurements has become a pain, that's why the capsule format has really exploded. These capsules, like every other capsule allows for easier dosing. Taking two capsules is way easier than dip and squeeze half a dozen times.
