Yes, just pouring it on but no don't rinse it off, just pat dry but first wash your face with a gentle cleanser (Nurtibiotic is what I use and it is a nice cleanser, not greasy, not creamy, nice and foamy but extremely gentle and leaves no film, I am sure you could find something just as good as this if you can't find this brand)from the organic store with no chemicals in it, so clean your skin with fairly warm water to get the pores open, rinse well, and then have your cup ready with the herbs in them and pour over your face but close your eyes! LOL then after about 30 seconds pat dry gently do not rub because that weakens the skin giving them more strength to invade and that is what probably causes inflammation which is typical of acne sufferers, wanting to scrub and almost always it gets worse. Then it probably gets angry from being disrupted from running it's cycle & burrows deeper. I am not certain on this all but it makes sense to me. And if you think about how acne is always described as "cyclic" up times and down times and it is probalby just the cycle of the invader (?).
I do think they are onto something on this forum that could actually eradicate a host of other issues people are suffering from...lol..seriously though if we look at some of the posts that are being shared about parasites causing sooo many things, this is probably just the tip of the iceberg we are all discussing and discovering. And yes, I believe clothing carries a whole lot of them..I recall one year I was really ill and everytime I would try something on at the store and pulled it over my head my face would turn bright red and get welts and bumps on my neck, chest and face...I had NO clue what it was other than I chalked it up as a chemical in the fabric so I quit trying on clothes and would wash them first before wearing them but now I have found that drying sweaters and jackets things like that and then putting essential oils on a cloth and running them all over the garment works and I never get that red inflammed bumps like I was getting bit all over!! what a world in which we live...lol.
