How do I add Medications back onto my watch after accidentally deleting it?

When I set up my new Apple watch, I accidentally deleted Medication from my apps - it's a part of the Health app, so I can't find a way to add it back. It's not a standalone app in the App Store. I also have set up medication reminders that I really need and I don't always have my phone (which is reminding me as it's supposed to) but always have my watch.
