Anyone doing steam baths for detox?

Greetings!

I am looking for ideas on what to put in my steam machine water as a means to detox. A friend of mine who is Chinese says her acupuncturist used some detox herbs in the steam as one of the methods to cure her mom from advanced breast cancer.

The only one that I've done is put some essential oil of rosemary to enhance circulation during my steam bath.

Any suggestions?

Thanks,
