I am one of the guys who put this on. You can look them up on the web like on Google by typing in Detox Foot Patches.
There are several brands and range in price from $1 a patch to $3 a patch. Zidiz Intl was the cheapest although I have had several brands and I wonder if the more expensive ones are a bit more potent. They all work but some seem a bit better than others.

I also can buy one brand in the local health food store here in California.

The theory is you put this tea bag looking item over
Accupuncture points and they are supposed to draw toxins out of your body. The other fellow who posted used them directly on this scrotum also. I did too after he did and I got much relief. The info says they need to be applied for about 30 to 60 days until things are pure. I have used for maybe 5 weeks now and on my feet basically nothing happens. But on my scrotum, it still really gets goopy by morning. But I was hurting really badly and in two nights I am feeling much better.

I will tell you they really, really have helped me. I will also tell you I do not believe anything like this can work.... But I feel better, my family say I am better, my boss noticed a big difference, and numerous people at church say I look better. So even tho I do not believe it... I do believe it I guess.

The reasoning the companies have is: your kidney /liver/ lymph do not remove all toxins. Some are heavy and sink to your feet or lodge in other areas. This is supposed to clean out your body's cleaning system.
