[Stoves] blood analysis as heath impact certification for "clean" stoves

[B.C. Romero Orellana]

concerning to point 3 the temazcal has a different disign and porpuse en
Mexico and Guatemala. In the area that we worked is use as a bath not
related with any ceremony as is done in Mexico.

In the picture you can see the disign. People use 2 or 3 timer each week.

here is one version of deaths in spanish.
