You should really ask your doctor who prescribed you these medications. Most people here are not qualified and licenced medical doctors. We might give you some information that you could have found yourself using an internet search engine, but that should not be taken as medical advice.
Since the plants you are interested in are not illegal anywhere, there is no reason not to ask your doctor about contraindications. Even for scheduled substances, you should be able to trust your doctor to give you sincere advice and not call the cops on you. If you cannot trust your doctor for that, find another doctor!
