There are a whole bunch of threads about this is the drug testing forum, but to answer your question anyways,

Most of the herbal cleansing drinks and so forth do nothing to actually rid the system of THC. The only way to get rid of THC in the body is through time and abstinence.

The drinks however, are usually chocked full of diuretics, B vitamins, and creatine.
The diuretics of coarse, cause you to piss a lot.
The B vitamins color your urine yellowish, so that the sample doesn't look dilluted.
The creatine is there so when (if) they test the creatine levels for dillution, it won't come up as such. (a note about creaine. I've read many times over that what they actually test for is creatinine, which is a metabolite of creatine, and supposedly the body takes 24 hours to metabolize creatine, hence forth making the creatine in the drinks essentially useless.)
They then have you fill the bottle multiple times with water, on top of telling you to drink plenty of water the day of the test and to urinate frequently before hand.
It's pretty much just dilluting your urine and draining your wallet.

SWIY could pretty much get the same effects as the drinks, by buying bulk creatine, B vitamins, and whatever SWIY favorite diuretic happens to be. (everyone has one!)
