Around 1735 chemical manufacturing which was largely sulphur derived ceased, which is how chemicals are made, this meant that largely a lot of chemicals used to make products went from having sulphur as a byproduct to none sulphur derived normally heavy metals…
Largely the species known as human race, has a dependancy on sulphur in it diet to provision natural course of healing and maintenance and in the right component which is dimethyl sulfone (MSM) is much very much like things you see in star trek like devices that cause the body to heal a wound or provide unstinting health; largely if this compound was included in manufacture requirements of food and drink as a % of sulphur on the ingredients printout the health industry would largely be anything up to 80% smaller and a large piece of placebo pharmaceutical basis of medicine like it is at the moment closed, to just mainly emergency services and the society we live in world wide would have little or lacking of the ill health, partly cause the need for sulphur in the diet from previous chemical manufacturing is a required dietary supplement.
MSM is largely sold for joint and pain relief in health food stores, but the link I have provided will allow you to order a food additive that you just sprinkle on your food or put in your tea and coffee as a spoonful each time. This compound is very much like the health surgical rays in star trek but a chemical variety you use as a dietary supplement, largely the pharmacology of today society is partly there as a designation too ill health, this is know in the medical industry and I am not the only one you can quote on the need for sulphur to be in all food and drink world-wide.
It is the same active component of those hippy videos you watch on youtube as pink sulphur salt, that is know even as a mix in a spray bottle with water as not to sting in application too cure cataracts and eye sight issues like what Perran Costi has when you have loss of sight, you are never to young to start sulphur treatment it is a deficiency in human society that largely leads to the complex health issues later in life.
Even when used as a pill packing component rather than chalk it can at times have health benefits of making the active component of the pill subjective and overall solution.
