I use passion flower leaves as a tea for anxiety. Don't steep longer than 4 minutes or it because undrinkably bitter. Don't disturb the teaball or water at all either, you want to keep that nasty bitter stuff contained, then remove it.
If I'm having a $%!*y day 2 big mugs makes me quite calm again.
I will sometimes use a facemask of a partly dissolved aspirin (no coating, put a few drops of water over/around it and wait 10 minutes, it turns to a course powder) and honey. Its messy, but its good to deal with acne. Calms it down. You can use this as a face scrub too. As a mask, don't use it more than twice a week or you'll build up a resistance. Aspirin (acetylsalic acid) is in a lot of acne products btw.
Taking zinc is also good for acne, it reduces sebum production and boosts your immune system. But be careful how much you take, it can make you throw up even if you have the ideal compound, zinc citrate. I was taking huge amounts for a while, and my face "dried up" noticeably, but now I just take 25mg a day for maintenance, as big amount for a long time will also interfere with you levels of iron, copper, calcium and especially magnesium, which is at the bottom of the absorption totem pole.
