Thank you! No, you need to remove in the insoluble fiber, which requires a juicer. A blender doesn't remove anything. Although if you have a nut milk bag, you can squeeze your blended stuff through that. It's time consuming and a pain in the arse though so I don't recommend it. Juicers are much easier.
Smoothies are obviously still amazing for overall health but they won't help you with mucoid plaque.
