Do I have to shake the Spit-less Mouthwash before use?

Why is it a yellowish color? Why does it feel gritty?

The Monk fruit powder in the Spit-less Mouthwash sometimes settles a little bit and that’s why it should be shaken. It is kind of a yellowish color because all vegetable & olive oil‘s are a yellow color and when used with the Monk fruit, it enhances the yellow color. The Mouth product should be shaken four-five seconds before use.
