I Am Presently Taking Prednisone .4 Mg, Hydroxychloroquine 400mg, Lisinopril

I am presently taking prednisone .4 mg, hydroxychloroquine 400mg, lisinopril (even though I have no blood pressure issues - to keep the protein level down in my urine), and lastly levothyroxine. I just started taking a herbal medicine (Deep Sleep) for insomnia which has valerian, passionflower, chamomile, lemon balm, oak and orange peel. Does lemon balm interact with any of these drugs?
