As for sida acuta this is all I know. The roots contain Ephedrine. So it will depend on what part of the plant you have.
I am very easily stimulated by some herbs and drugs. I could not take Sida Acuta. But, remember we are all different and will react differently to each herb.
The best thing is to try it early in the day to see if it affects you.
As for Houttuynia, I had no difficulty with it. But, here again..... someone else might.
This is why we test each herb individually to see if they affect us. Trying 2 herbs together is not recommended because then you will not know which one caused a reaction, if you should get a reaction.
