I have propolis. I tried it recently but it didn't do much. I already take so much stuff that it went on the 'can't justify the extra expense' list. But I'm keeping it handy for infections etc.It is extremely important for so many things and you better keep your copper low anyway cause it's not like it is particularly good for you.
Zinc will also help keep your skin oil in check and your skin will be much stronger and if you cut yourself it heals faster.
Check out propolis next which is what bees use to fend off bacteria and fungus but go for the non alcohol one, the black propolis.
