After Zentherapy bodywork, we tell all clients (and practitioners) that they need to take a detox bath to help eliminate the toxins that have been released during the work. The detox bath consists of 1/3 cup of sea salt, 1/3 cup of epsom salt and 1/3 cup of baking soda into the bath water. ~OR~ One cup of apple cider vineagar poured into the bath.
The best option, we're always told, is to just jump into the ocean if it is nearby. I just read something in The Aromatherapy Companion that seems to make the same point about how sea water is ideal for detoxing:
Thalassotherapy is water therapy with the addition of elements from the sea, mainly seawater and algae. The theories of thalassotherapy are based on the premise that there exists a physiological similarity between the ocean and blood plasma. Our blood does contain certain minerals, notably potassium, sodium, and chlorine, in the same proportions as seawater. It is believed that by warming seawater to body temperature, negative ions are activated; these penetrate the body, bringing the vital elements of the sea to our every organ. The remineralizing benefits of thalassotherapy are considered to be especially effective in restoring elasticity to sagging skin due to aging or sudden weight loss, or following a pregnancy.
The author (Victoria Edwards) recommends adding 2 to 4 ounces (60 to 120 ml) of algae powder to a bath. She says this should help restore healthy skin texture, blood circulation, reduce cellulite and water retention, and soothe sore muscles.
