HONOLULU (KHNL) -- Feeling a bit achy? Do you suffer from insomnia or fatigue? A popular product advertised on television, claims to be the "ancient Japanese secret to perfect health."
Could the Kinoki Cleansing Detox Foot Pads, help you feel better?
They claim to work, while you sleep, by absorbing impurities.
So we had to try them out. I wore them on my feet for a bunch of nights.
An unused foot pad is plain white. After one night of use, the foot pad turned a greenish, grayish color.
But I didn't feel any different.
My colleague, videojournalist Sisto Domingo, also tried the foot pads.
"I didn't feel any real difference. Whatever slight difference I felt, I think it was psychological," he said.
So, we asked a physician, specializing in environmental medicine, does it work?
"For detoxing heavy metals and poison, probably not," said Curtis Takemoto-Gentile.
He says labs have tested used, Kinoki foot pads. Mercury or other main toxins, could not be found. But why do they change colors after you wear them? This doctor says the answer, lies in the ingredients of the foot pads.
"And one of the ingredients was bamboo vinegar, and it's supposed to be fermented for 9 years. And I think it's a combination of that and green tea and moisture and heat from the sole of the foot," he said.
