Is it possible to use sedative herbs when using Concor?

Good morning, I was on a visit to a cardiologist with the problem of extra contractions. All tests came out normal and I was given Concor 1.25 mg. Because I suffer from anxiety for various reasons, I also got herbs from a herbalist. The mixture is liquid and contains St. John's wort, passiflore, lemon balm and bark of the Jamaican tree. The mixture contains alcohol. I forgot to ask the doctor if I could use it to calm down.
