Detoxification foot pads
Detoxification foot pads are adhesive foot pads or patches that manufacturers claim can dramatically improve health when placed on feet during sleep. Some of these pads may contain ingredients like "distilled bamboo vinegar" that allegedly pull toxins from the body. Some have claimed that these products are not effective, because the skin is only semi-permeable and is not able to conduct toxins out of the body. However, several studies conducted with the sap sheet range of products from Japanese company Kenrico have demonstrated their effectiveness in boosting mental and physical health, as well as removing heavy metals.
On January 3, 2008, the FDA released an urgent warning regarding the potential dangers of many imported pharmaceutical substances including several brands of detox foot patches. This was due largely to many low quality and potentially dangerous detox pads sold through manufacturers in Korea and China, while patented skin patches from Japanese manufacturers using natural ingredients like nattokinase and sporopollenin have been demonstrated in clinical studies as being effective in heavy metal detoxification. Different products from different companies have varying levels of quality, safety and effectiveness.
In April, in response to questions from the Associated Press, an FDA spokeswoman said regarding the agency's investigation of the claims made for Kinoki foot pads that "basically, when we open up a case it means that the violation might be in terms of the Food, Drug and Cosmetics Act, such as when (product makers) make false, misleading claims."
In August 2008, National Public Radio commissioned a laboratory test to look for heavy metals in used pads, which Kinoki claims are extracted from the body. The test found none. NPR also discovered that the pads change from white to grey when they are exposed to moisture, including sweat (not necessarily because they are absorbing other substances).
