Bringing the Cedar Enzyme Bath
to the United States

Japanese Cedar Enzyme Bath

Osmosis founder Michael Stusser opened the first Cedar Enzyme Bath in this country in 1985. He discovered the bath in Japan, where he had been studying traditional landscape gardening and Zen. His first plunge into the Cedar Enzyme Bath was a life-changing healing and spiritual event that convinced him that it was his mission to bring it back to the US. Soon after returning from Japan he built a prototype 400-square-foot facility in a Sebastopol backyard out of recycled wood from a chicken coop. 

The Cedar Enzyme Bath is the outgrowth of a centuries-old Japanese tradition

 A Big Hit

Word caught on quickly when the bath was written up in the Sunday section of the SF Chronicle in 1987. Since then the popularity of the Cedar Enzyme Bath and Osmosis has grown steadily.

A Home in Freestone

Osmosis moved to its current location in Freestone in 1989, where Stusser and a dedicated staff have enhanced and expanded the facilities and services ever since. The most recent addition is the Meditation Garden, a four-year project dedicated in June of 2003.
