There are things you can do for yourself to detox, relax, and just enjoy a luxurious bath.
I am not a doctor. I am not prescribing any of these which are just suggestions and info I have found from different sources. Please do your own research. These are just natural ideas to use. I have used them all myself for baths and for other things such as salt water rinse for the mouth and soda can be added to the rinse as well.

I have used this brand of Mineral Bath Soaks for years. It is one that I am not sensitive to. Sometimes I will mix them in one bath. I really like the Cold & Allergy Mineral Bath Soak. Walmart used to carry all three.

Epson Salt has been used over the ages.

Soda Baths are good to detox heavy metals.
The following soaks are to help you cleanse. They will help to detoxify petrochemicals, pesticides, radiation and synthetic compounds from your body.
Hydrogen Peroxide Soak: (to Detoxify pesticides and other chemical compounds. This works more gently then Clorex.) Ad one (1) 16oz bottle of 3% Hydrogen Peroxide to a full tub of water. Soak for 30 minutes. Muscle test how many soaks are needed.
Clorex Soak: (to Detoxify pesticides and other chemical compounds. Add 1/2 Cup of Regular Brand Clorex Bleach to a full tub of water.
NO OTHER BRAND OF BLEACH WILL WORK AND MAY BE HARMFUL. (I don’t know why, however every source I have used this for says the same things)
Salt and Soda Soak: (To detox Radiation
To cleanse fruits and vegetables use 2 Tablespoons of Clorex to 2 Gallons of water. Soak for 10 minutes. Rinse well. This works at a homeopathic level. I have found they stay fresher longer when I do this.
I also use a Clearing Board from DynaPro International to clear my food.
