I have been eating a lot of spinach and broccoli, for maintaining good health, as well as taking 1600 mg. of Valerian pills, at night, to help me sleep. with my having bad insomnia . My stools have been greenish the past few days, and I am worried. Will my taking the Valerian or the green vegetables I am eating contribute to my having these green stools? I am very concerned about this problem.
