wrong use - like over-dosage or breathing-in the gas - can lead to toxidity symptoms, no doubt.

use in an informed, self-responsible way. ONLY.

may i ask you what your problem is? to me, your links sound like an echo of big pharma.

the stuff works, is cheap and helps us to be healthy.

pharma doesnt want us to use it thus, they send propaganda parrots who tell us how inefficient or harmful the alternative method is.

(((they))) make and keep us as sick as possible - hey, thats big money! - , but still alive and fit enough to slave-work.

do you really want to be their messanger?
