Chi Detox Foot Patches (10). Chi Detox Patches help to detox your body while you sleep.. We all carry toxins around in our body. They accumulate as we live: nasties like environmental poisons, chemicals we breathe in or ingest, waste products from foods all get stored in our body tissue. Chi Detox Patches are a unique, non-invasive way to help detox the whole body. Each patch contains a unique formula of highly purified powder extract of a blend of herbs and minerals used in Chinese Medicine. They target the reflex points under our feet, which have 62 acupuncture points.. Simply apply them at night. When you remove the patches in the morning, you can see the changes: their colour will show you that they have absorbed sweat from your feet over night.
