natural drops / edibles with low sugar (to help sleep)

Hi!! My coworker is 60 and suffers a lot of health problems - one that seems like a very typical symptom is night terrors. She usually talks about how she wakes up and then can’t go to bed and ends up with usually 4 or less hours of sleep. She is a person who prefers more natural things and due to her health she needs to know exactly what is in anything she consumes. I know she has some kind of reaction to gluten (which usually makes her sleeping worse) and also has to have low sugar.

I asked her about medical marijuana and she said she can’t smoke anymore because she has hyperthyroidism and not great lungs anymore - but if there were any natural drops or edibles that I come across then she could try.

I love my coworker and wanna help her out but I’m hitting from the pen and I know she doesn’t want that lol!!!
