burbur pinella and parsley - a question

I'm taking burbur and pinella, which I take together. I now want to add parsley - so, please, could those of you who take these let me know - is it OK to add the parsley to the burbur and pinella and take them all in one go, or do I need to take the parsley separately. Thank you!

Many thanks for your help. That's great. Much appreciated.
