I'm not sure if they have herbal supplements on it. I only glance at it when I first started. It's a possibility that they had it cause I think it had like mouthwash on it. If you use the app click on help desk and select guides and documents. They have a list of different topics including a medication guide. I just don't drink or do drugs and all my test do fine. I know some people be like you can't use soy sauce, vanilla extract, perfume or bug repellent spray lol I used all these and never had a problem.
